2. Query the temperature inside the MA5600. It is found that the temperature even reaches 48°C,
and the fan block alarm is generated.
3. Pull out the fan tray. It is found that the fan responsible for slots 13 and 14 has stopped

n:
Alarm name: fan block alarm
Parameters:
Alarm description: fan block alarm
Alarm cause: Some subjects block the fan.
Troubleshooting suggestion: Check the fan.
The temperature inside the device is too high, the fan block alarm is generated, and the ADSL
service boards in slots 13 and 14 cannot provide the internet service. After the analysis, it is
estimated that one of the six fans in the fan box of the MA5600 fails, and this faulty fan is
responsible for the heat dissipation of the ADSL boards in slots 13 and 14.
The prerequisite for generating the fan block alarm is the hardware failure of the fan.
According to the fault analysis, it is determined that the fan fails. After the fan is removed and
s:
checked, we confirm that the hardware fault of the fan exists. That is, the fan responsible for the
heat dissipation of the slots 13 and 14 fails.
After a new fan is installed, in half an hour, query the temperature of the device. It is found that
the temperature falls, and thus the ADSL service boards in slots 13 and 14 no longer
automatically restart and the service ports are not dead locked.
The high temperature of the device usually results from the failure of the fan in the device. When
the fan fails, query the alarm and replace the fan in time to avoid burning the service board or the
backplane.

Cause Analysis:
Troubleshooting Cases Quality Level:
Type :
The traffic suppression is used to suppress the traffic of the broadcast, unknown unicast, and
iption:
unknown multicast packets in the inbound direction of the port. For the broadcast and unknown
unicast, the suppression is implemented according to the number of the packets. For the
unknown multicast, the suppression is implemented according to the traffic of the packets. This
command is mainly used to avoid the effect on the system and the network after a large number
of such packets are broadcasted.
The broadcast packets refer to the packets whose destination MAC addresses are all Fs, such as
ARP packets, PADI packets in PPPoE protocol, and DHCP discover packets in DHCP protocol.
Many protocols send the handshake packets through broadcast.
The unknown unicast packets refer to the packets whose destination MAC addresses are unicast
MAC addresses. In the LAN switch chip of the control board, however, no forwarding entry
related to the destination MAC addresses is created, so the LAN switch chip does not know to
which port the packet is forwarded. In this case, the MA5600 broadcasts the packets in the
VLAN where the port that sends the packets is located. If too many unknown unicast packets
(for example, caused by the malicious attack) are broadcasted, the congestion occurs or even the
ongoing service is interrupted. Therefore, the traffic suppress command is used to suppress the
unknown unicast packets.
The unknown multicast packets refer to the packets whose destination MAC addresses are
multicast MAC addresses (the highest bit of such MAC address is 01, such as the MAC address
of IGMP packets and some BPDU packets). In the LAN switch chip of the control board,
however, no forwarding entry related to the destination address is created, so the LAN switch
does not know to which port the packets are forwarded.

transmitted or discarded. For details, refer to "Introduction to the Traffic-suppress Command" in
this document.
Handling Proces
Implementation principles:
s:
Broadcast and unknown unicast packets: The traffic is suppressed according to the number of the
packets. After the port on which the broadcast suppression and the unknown unicast suppression
are configured receives the broadcast and unknown unicast packets, the chip counts the number
of the packets. At a certain interval, if the count reaches the preset threshold, the chip discards
the broadcast and unknown unicast packets that the port later receives until the next interval
starts. When the next interval starts, the counts of the broadcast and unknown unicast packets
received by the port are cleared.
Unknown multicast packets: The chip does not support the traffic suppression by the number of
the packets, so the traffic can be suppressed only according to the bandwidth in the ACL mode.
In this case, the bandwidth that equals to the number of the packets transmitted to the host
multiplied by 512 bytes (the average length of a packet is 512 bytes in calculation) is set in the
chip.

modems on the same port work in the normal state.
The 678 error is displayed through the dialup on the PC.
n:
After the cutover, the sub-port is re-planned only on the MA5200G. That is, VLANs are
transparently transmitted on the S7802. Therefore, it is possible that the fault is caused in the
following conditions:
1. On the MA5200G, the configuration of the inner VLAN of the QinQ VLAN is incorrect, or
the range of the inner VLAN is small.
2. The network planning of the S7802 is incorrect.
1. Check the data of the MA5200G. It is found that the data is correct.

It is found that the 678 error is displayed because the S7802 learns the MAC address of the PC
connected to the modem of the A company, and the MAC address corresponds to VLAN 19.
3. Check the condition that the MA5600 learns the MAC address of the PC. The condition is the
same as that displayed in step 2. After PVC 8/46 carrying the E8-2 service is deleted on the

the cutover, the E8-2 services with the VLAN 19 tag of different MA5600 devices are
terminated on different ports of the BAS; after the cutover, the E8-2 services with the VLAN 19
tag of all the MA5600 devices are terminated on the same port of the BAS within one broadcast
domain. On any port of any MA5600, after the modem of the A company receives the PADI
packets with the VLAN 19 tag from other MA5600 devices, the PVC automatic search function
is enabled, and it is determined that the PVC of the modem of the A company is PVC 8/46. The
modem of the A company is a single-PVC modem, so when the PVC is determined to be PVC
8/46, other PVCs (including PVC 0/35 for Internet access through dialup) are deactivated by the
modem. In this case, the 678 error occurs when the user connected to the modem of the A
company goes online through dialup.
5. There are four ways to solve the problem:
1) Replace the single-PVC modem of the A company with the multi-PVC modem.
2) Delete PVC 8/46 on the DSLAM device. The modems that do not provide the E8-2 services
are in the bridge mode, so only PVC 0/35 is needed for the dialup.
3). Enable the port isolation on the S7802 to prevent the broadcast.
4). Re-plan the data, and ensure that the E8-2 management VLAN 19 of each DSLAM device is
labeled with the service VLAN to prevent the broadcast.

Dual PVCs (0.35) and dual services (Internet access and IPTV) are configured on the ADSL port of
the MA5600. On the S6506 and BAS, the corresponding data is configured. The Internet access
service and IPTV service adopt the dialup mode, using two types of accounts respectively.
When the common modem providing a single Ethernet port is used, sometimes error 691 is

2. When the modem providing four Ethernet ports is used, the service is always normal. Therefore,
it can be determined that the BAS is properly connected to the RADIUS server.
3. When error 691 for the subscriber connection is displayed, it is found that PVC (0,35) cannot be
pinged but PVC (8,81) can by running the atm-ping command. Therefore, it can be determined that
the connection between the modem and the MA5600 adopt PVC (8,81) but the account is that for
the common Internet access service. Thus, error 697 is generated.
By default, these two PVCs (0,35) and (8,81) are configured on a common modem, which chooses
a PVC at random when the MA5600 is configured with multiple services. Test shows that the fault
cannot be rectified if PVC (8,81) is deleted. Delete the IPTV service configured on the MA5600
ADSL port. It is found that the fault is rectified.
Among the four Ethernet ports of the modem, by default, the first two use PVC (0,3 5), used for the
Internet access service, and the last two use PVC (8,81), used for the IPTV service. No additional
PVC exists, so no fault occurs in the case of the four-port modem.
Furthermore, we can set the common modem to work in the auto-dialup mode (VPI 0 and VCI 35 is
used) to avoid such a fault.

terminal management.
2. The PPPoE dial-up service is enabled on the BRAS for the four VLANs.
3. The user account is bound to VLAN 10 on the RADIUS server.
When non-multi-PVC users dial up, sometimes the 691 error occurs, and sometimes the 678
error occurs. When the modem of the user is powered off and reset, the user can dial up
successfully sometimes; when the board on the device is reset, the user can also dial up

1. When the user dials the numbers, the PADI packet is sent from the user side. After the PADI
packet arrives at the ADSL service board, the packet is broadcast to the four PVCs. After the
BRAS receives the PADI packet, the BRAS processes the packet and responds with the PADO
packet because the PPPoE dial-up service is enabled for the VLANs of the four PVCs. Then,
based on the line conditions, latency, and the time required for the processing on the BRAS, the
modem adapts to only the PVC whose PADO packet is received first by the modem. Then, the
modem does not adapt to other PVCs, because the modem is a single-PVC modem.In the

networking of this case, assume that the PADO packet of PVC 0/33 is received first by the
modem, the modem adapts to PVC 0/33 and does not adapt to other PVCs any more.When the
PC of the user sends the PADR packet, only PVC 0/33 is available now. After the PPP packet
exchange, the user authentication packet is sent to the RADIUS server. On the RADIUS server,
the user account is already bound to VLAN 10, and now the user authentication packet sent
through PVC 0/33 carries VLAN ID 20, the 691 error occurs consequently.
2. If the dial-up service is not enabled for the four VLANs but is enabled for only VLAN 10
instead on the BRAS, the BRAS does not respond to the packets sent through the other three
PVCs, and responds with the PADO packet to the packet sent through the correct PVC only.
Therefore, in normal conditions, the user can dial up successfully. If the 678 error occurs in such
a case, check which PVC is currently effective on the modem. If PVC 0/32 (carrying the dial-up
service) is currently not effective, it is natural that the 678 error occurs, because the dial-up
service is not enabled for other PVCs on the BRAS. Before the user dials up, a certain PVC has
received a packet (a broadcast packet or protocol packet from the network) sent from the
DSLAM port. As a result, a link is set up between the modem and this PVC, and the modem
does not negotiate with other PVCs. Hence, the 678 error occurs.
Handling Proces
The solutions to such problems are:
s:
1. On the single-PVC modem, configure only one PVC and delete the other PVCs. For
multi-PVC users, configure the multi-PVC service on the multi-PVC modem.
2. The DSLAM of certain versions supports the deactivating of the PVC. Upgrade the DSLAM
to such a version and deactivate the PVCs that are currently not used.
3. Replace the single-PVC modem with a multi-PVC modem.
Suggestions and
Summary:
The problems discussed in this case occur in the ONE HOME service of China Telecom. In
many areas, the multi-PVC service is configured for users whose modems currently do not
support the multi-PVC service. Because of the implementation mechanism of certain single-PVC
modems, the problems occur. The problems do not relate to the device quality.

1. View the configurations. The loop detection function is enabled.
s:
2. Deactivate all the ports manually one by one to locate the faulty port, because the new
MA5600 does not have many users.
3. After port 0/0/4 is deactivated, the S8505 does not report the loop alarm and the user reports
that the dialing is normal. Therefore, the loop exists on port 0/0/4.
4. Check on site. It is found that the user connects two ADSL lines (the corresponding ports are
0/0/4 and 0/0/5 respectively) to the hub to increase the bandwidth. Thus, the loop occurs.
5. According to the designed loop detection mechanism of the MA5600, the PC connected to the
modem can capture the loop detection packet (see the attachment) whose destination address is
0180-c200-0011. When the PC is connected to the modem of a certain type that is connected to
port 0/0/4 and port 0/0/5, the PC cannot capture the loop detection packet whose destination
address is 0180-c200-0011. Therefore, the packet is discarded by the modem.
5. After the modem to which port 0/0/4 and port 0/0/5 are connected is replaced by the MT800,
the PC can capture the loop detection packet whose destination MAC address is
0180-c200-0011. 6. Use the MT800 and set up the loop network again (that is, both cables are
connected to the hub). In this case, the MA5600 reports a loop alarm and deactivates the port.

7. The modem of a certain type (no manufacturer is indicated) cannot transparently transmit the
loop detection packet transmitted by the MA5600 with the destination address 0180-c200-0011.
Thus, the loop detection function fails.
Suggestions and
Summary:
Currently, the loop detection function of the MA5600 V300R002 can be implemented only if the
modem of the user transparently transmits the BPDU packet that is used for the loop detection. If
the modem of the user does not transparently transmit the BPDU packet that is used for the loop
detection, the loop detection function cannot be implemented. The modems in the existing
network are various. Most of the modems, however, do not support the transparent transmission.
Therefore, the loop detection function cannot be implemented in the existing network.
The loop detection function of the MA5600 V300R003C05 is optimized. The loop detection
function is implemented through a private packet, and the protocol type can be set. If a port
receives the loop detection packet transmitted by the MA5600, the MA5600 deactivates this
ADSL port that receives the packet based on the information of the ADSL port in the packet.
Thus, the loop network on the user side can be prevented.

are normal. In addition, the user can watch the unscrambled channels.
Alarm Informatio
Cause Analysis:
Run the debug IGMP packet command on the MA5600 and it is found that the MA5600 can
n:
receive the report messages from the multicast groups with the IP addresses 226.1.1.1 and
226.1.3.10. The MA5600, however, prompts that the programs do not exist.
The possible causes of dark screen when end users watch live channels are as follows:
1. The hardware of the STB terminal is faulty or the STB is not configured properly..
2. The home gateway is not configured properly or the physical connection of the home gateway
is improper.
3. The DSLAM is configured improperly. For example, the multicast programs where dark
screen occurs are not configured, or the IGMP bandwidthCAC command is executed.
4. The upper-layer multicast router is faulty, which causes that the multicast stream is not added
to the terminal.
5. A certain head-end system of the IPTV, such as the CA system, encoder, or middleware, is
faulty.
Handling Proces
According to onsite tests, the fault is not caused by the user-side network or improper
s:
configuration of the DSLAM. It is confirmed that the subsystems at the head-end of the IPTV
work normally. In addition, the multicast stream is issued when the user demands programs,
which is confirmed by the port traffic information queried on the DSLAM. Hence, the fault is
not caused by the upper-layer multicast router. Through the analysis of the symptoms and scope
of the fault, it is found that the fault is caused by the CA system at the head-end of the IPTV.
This is also proved by the fact that the terminal end can watch unscrambled channels.
The CA system is a product of a third-party manufacturer. The manufacturer explains that the
fault occurs because the encryption key of the CA card in the STB expires. Usually, the
head-end CA system transmits the group and global EEM streams to the CA system periodically
to update the encryption key of the CA card. The group and global EEM streams are transmitted
through multicast addresses 226.1.1.1 and 226.1.3.10. The validity period of the CA card is
preset when it is delivered from the factory. If the CA card fails to receive any updated EMM
streams during the validity period of the encryption key, dark screen occurs when IPTV users
watch scrambled live channels under the MA5600 after the encryption key expires.
According to onsite tests, the encryption key of the CA card fails to be updated mainly because
of the following causes:
1. The MA5600 is not configured with the multicast programs that issue the EMM streams.
Hence, the STB cannot receive the EMM streams to update the encryption key of the CA card.
Run the debug IGMP packet command on the MA5600 and it is found that the MA5600 can
receive the report messages from the multicast groups with the IP addresses 226.1.1.1 and
226.1.3.10. The MA5600, however, prompts that the programs do not exist.
2. The STB of certain versions is configured with an incorrect update address when it is
installed. Hence, the version of the STB fails to be updated. In this case, the STB does not
request the DSLAM to issue the EMM streams. That is, the STB does not transmit the report
message.
3. The fault is caused by personal behaviors of the end user. For example, the user does not
watch TV for a long time. The STB is in the shutdown state, and thus the encryption key of the
CA card fails to be updated. In this case, the user needs to wait for 90 minutes at most after
starting the terminal so that the encryption key can be updated.
Suggestions and
Summary:
This fault cannot be recognized easily, and thus is not recognized during earlier PAT and FUT
tests. The IPTV is a complicated system that contains a number of products. Hence, we need to
learn the service flow of the entire IPTV system profoundly. In this case, the MA5600 fails to be
configured with the multicast programs that issue the EMM streams because the access network
engineers do not know the CA system and engineers from different product lines lack
communication with each other. The EMM streams are not common media program streams.
Hence, the terminal user can watch live channels normally even if the precedingly mentioned
multicast programs are not configured on the DSLAM.
In the case of long period for the first update of the encryption key after it expires, the
third-party manufacturer optimizes the parameters of the CA system according to the
requirement of Huawei. Currently, the update of the encryption key of the CA card in the STB
terminal requires less than 20 seconds.

Therefore, it can be determined that the data configuration of this MA5600 is correct.
3. Check the configuration of the convergence switch. It is found that the port of the MA5600 is
configured with "broadcast-suppression 1", which indicates that when the broadcast packets
occupy more than 1% of the total port bandwidth, the excessive broadcast packets will be
discarded. During the peak hours, the bandwidth occupied by various broadcast packets
(including the normal ARP request packets, PADI packets and the packets transmitted by the PC
after being infected with viruses) exceeds 1% of the total bandwidth. As a result, the PADI
packets transmitted by the new dialup subscribers are discarded, which results in the dialup
failure. Disable the broadcast suppression on the port of the convergence switch, and it is found
that the fault is rectified.

many eqipment. And finally I checked the line condition
at the port. At some ports the supported Upstream Channel
SNR Margin was 16.5 dB and downstream Channel SNR Margin was 23 dB
but configured Upstream Channel SNR Margin is 31 dB and
downstream Channel SNR Margin is 46 dB (As per Configuration).
Due to this mismatch the problem was arised.
This SNR Margin check was applicable for all versions.

The problem was arised due to faulty physical line.
The available physical line didn't support the

of new physical line were matched with our requirements.
To check the SNR margin i use this command
"display line operation port port_no."
Suggestions and
Summary:
This will be very useful when we are implementing any
service on any port. Before providing any service to a
customer ( on any particular port ), we should check the

solve the problem. Why?
Alarm Informatio
Cause Analysis:
Null
n:
BandwidthCAC---multicast bandwidth check, when it is set to disable, the bandwidth check is not
performed. Be default, it is set to enable on the MA5600.
The multicast bandwidth check is classified into the check on the uplink port bandwidth and the
check on the user side bandwidth. Simply speaking, when the bandwidthCAC function is enabled,
check the uplink port bandwidth: compare the bandwidth allocated to the uplink port with the
bandwidth to be used by the uplink port program. If the former bandwidth is larger, you can order
the program. Otherwise, you cannot order the program.
Check the user side bandwidth: Compare the bandwidth allocated to the user with the bandwidth to
be used by the user. If the former bandwidth is larger, you can order the program. Otherwise, you
cannot order the program.
The bandwidth allocated to the uplink port is the product of the uplink port bandwidth and the
percentage of the bandwidth allocated to the multicast.
The bandwidth to be used by the uplink port program is the bandwidth sum of the programs bound
to the uplink port.
The bandwidth allocated to the user is the product of the downstream rate of the user port and the
percentage of the bandwidth allocated to the multicast user.
The bandwidth to be used by the user is the bandwidth sum of all the programs ordered by the user.
This is the reason that you can solve the problem by modifying the program bandwidth.
Handling Proces
igmp bandwidthCAC { enable | disable }
s:
This command is used to enable or disable the multicast Connection Admission Control (CAC) of
the uplink port and the user port, which is called the bandwidth management function. When you
need to restrict the bandwidth on the uplink port and the user port for the multicast program, you
can run this command to enable this function. After the bandwidth management function is enabled,
the bandwidth restriction on the uplink port takes effect immediately. The bandwidth restriction on
the user port takes effect when you order the program the next time. After the multicast CAC
function is disabled, the multicast bandwidth management is not performed for the uplink port and
the user port. The system does not guarantee the bandwidth of the multicast program.
When the CAC function is enabled:
1. Check the maximum multicast bandwidth that is allowed by the service port for passing.
2. Query the bandwidth of the program that is being played by the service port. 3. If the band width
of the required program is larger than the remaining allowed bandwidth of the service port, you
cannot order the program. Otherwise, you can order the program.

of the required program is larger than the remaining allowed bandwidth of the service port, you can
order the program. If the allowed bandwidth of the service port is insufficient, the packet loss
occurs. In this case, the multicast service is unstable.
Suggestions and
Summary:
The program bandwidth is statically configured when the multicast program is added. For the actual
IPTV service application, the program rate of the multicast source of the carrier should be
invariable. When configuring the multicast program on the MA5600, ensure that the program
bandwidth is configured the same as the bit rate of the program source of this program. In this way,
the bandwidth check can be effective.
The main purpose of the bandwidth check is to check and ensure that the total bandwidth occupied
by the program of the uplink port/user port does not exceed the rate actually supported by the uplink
port/user port (otherwise, the packet loss occurs). If you can ensure on the networking that the total
bandwidth occupied by the program of the uplink port/user port does not exceed the rate actually
supported by the uplink port/user port, you can disable the bandwidth check.

How does the MA5600 support the anti DoS attack function?
Null
n:
Null
A:
s:
The anti Dos attack in the MA5600 is a function that the system detects whether the DoS attack
occurs with the physical port as a granularity for xDSL boards.
The principle:
After the security anti-dos enable command is executed to enable the anti Dos attack function
successfully, the system limits the rate of sending the packets to the CPU of each service board
to 20 pps.
Meanwhile, the packets sent to the CPU of each service board are detected once every five
seconds, and the detection is performed four times consecutively. Every time the rate detected
exceeds 20 pps, it is regarded that the DoS attack occurs.
Then, the port sending the packets is added to the DoS blacklist, and an alarm is generated.
The MA5600 system does not change the status of the port added to the blacklist, but prohibits
the port from sending the packets to the CPU of the service board. Other service packets,
however, can be forwarded (the forwarding is performed by each service board). Meanwhile, the
system starts a timer with the duration of 180s. When the timer times out, which means that

within 180s, no DoS attack occurs (To CPU packet <= 20pps), the port will be removed from the
blacklist and the restriction will be released. In addition, a recovery alarm is generated.
Suggestions and
Summary:
(1) The system can prevent the subscribers from implementing the DoS attack by using various
types of control packet, including the PPPoE discover, DHCP, ARP, ICMP, IGMP, PPP LCP
and BPDU packets.
(2) The system supports up to 1024 items in the DoS attack blacklist.
(3) When the DoS attack occurs, the system will generate an alarm within 20s.
(4) For MA5600V300R003/V300R002, the anti DoS attack function is enabled in the same way.
(5) The system generates an alarm when a DoS attack occurs or disappears.

Fault phenomenon: The customer complains that the port can be activated but the connected
hotspot access service fails.
Alarm Informatio
Cause Analysis:
Null
n:
The problem of activation success but access failure involves the entire shelf. In addition, it is
confirmed that multiple sites have the similar problems. The involved service is single (hotspot).
At the time, the customer tries to enable anti-MACspoofing, which causes the special service
disconnection. Therefore, the hardware or system fault is excluded. The possible cause is that the
terminal device is incompatible with the system configuration.
Handling Proces
1. After a query, it is found that the port is in activated status and passes atm-ping. It indicates
s:
that the channel between the CPE and the board is smooth.
2. Query the MAC address learnt by the port. It is found that no MAC address is obtained. The
wireless AP problem is excluded.
3. After the MACspoofing is disabled, the service is in the normal state. The port can learn the
MAC address. The problem focuses on why the CPE cannot send the packets with the MAC
address in the normal state.
4. It is found that other IPoA users configured with the static IP addresses are not affected.
According to query, the MAC addresses can be obtained but are assigned by the system MAC
address pool.
5. Add the MAC address of the modem manually to the system. The problem is solved.
6. It is confirmed that the problem is caused by the terminal modem, which is configured with
the static IP address. In this case, there is no DHCP/ARP interaction, and the authentication
mode is not PPPoE/A. Therefore, the MA5600 cannot obtain the IP address.
Suggestions and
Summary:
After anti-MACspoofing is enabled, the mechanism for the MA5600 to learn the MAC addresses
changes, which is that passively wait for the port to interconnect the modem and the MAC
address is intercepted from the PPPoE/A,DHCP/ARP packets. The problems occ ur in this case
mostly because the port cannot obtain the MAC address. The disable MACspoofing MAC
function is obtained by the service board negotiating with the modem through the inAtmArp
protocol. Therefore, this problem does not occur. In addition, the services to which the system
uses the MAC pool to assign the MAC address type of the port are not affected, such as IPoA
services.

Alarm Informatio
Cause Analysis:
Handling Proces
Suggestions and
Summary:
Null
n:
The modem can be activated but a large area of the entire shelf fails to go online or goes online
very slowly. The main possible causes are as follows:
1. The backplane or the service board cannot communicate with the control board (upstream) in the
normal state.
2. The profile configuration is incorrect and the line has interference.
3. A virus occurs in the MAC or IP address spoofing.
4. The upstream daughter board, fiber line, or interconnection switch of the MA5600 is faulty.
Complaint process: The customer receives occasional complaints against the failure to go online.
s:
After a checking, it is found that the port is in the normal state and the modem can be activated for a
successful access. The complaints, however, persist. After the port is performed with migration
(replacing the slot), the complaints persist. After a week, the number of complaints increases. The
customer requires Huawei to assist in the investigation. The initial complaints against the port
activation failure cause great trouble to identify the problem. Subsequently, it is confirmed that the
port can be activated successfully. The problem is identified as follows:
1. After the service runs on the existing network for a while, no hardware alarm is reported. The
problem lies in the entire shelf. Multiple service boards are replaced. The hardware problem is
excluded.
2. The line profile configuration complies with the line profile configuration in other sites of the
existing network by trying the interleaved mode. Then, the problem is not solved. The loopback and
the afe atm-ping are in the normal state.
3. Enable the anti IP address spoofing and anti MAC address spoofing functions for the host, and
there is no record in the security blacklist.
4. Consult the upstream peer switch, and there is no ecrc error or other error code record. The
PPPoE authentication and access are smoothly successful.
5. Connect the PC and the modem to the MA5600. The DHCP, DNS, and PPPoE packets are
captured completely. The web site cannot be opened. After the optical module is replaced, the fault
persists. After the customer replaces the interconnected switch port, the fault still persists. Use the
special fiber detector to find that the RX is normal and the error code rate of the TX lower layer is
relatively high. After the fiber is replaced, the problem is solved.
For the existing network problem, you need to identify the affected range of the single port, multiple
ports, board, cross-boards, and entire shelf, and then identify the problem from software to
hardware. If the protocol is in the normal state, identify the problem at the lower layer. For example,
the fiber error code may not be displayed by capturing the ethereal packets.

A:
s:
The heat generated by the 64-channel service board is more than that of the 32-channel service
board, so the power of the fan tray for the 32-channel service board cannot meet the requirements
on the heat dissipation of the 64-channel service board. If the 64-channel service board is installed
in the slot for the 32-channel service board, the 64-channel service board may be faulty. Therefore,
the 32-channel service board is not slot compatible with the 64-channel service board.

How to connect and configure the humidify sensor in the H304ESC?
None
n:
None
A:
s:
As for hardware connection, the H304ESC provides many JTD interfaces and JTA interface.
Where, the JTD interface is used for connecting the digital parameter sensor, and the JTA interface
is used for connecting the analog parameter sensor.
In general, the humidity sensor is an analog parameter sensor. Therefore, it can be connected to
the JTA2 interface.
As for software configuration, see the Command Reference of the corresponding device. The
following shows an example of the command.

For how to select the analog parameter ID when running this command, see the Command
Reference of the corresponding device. For example, the Command Reference of the MA5600
provides the following description:
0: is the default inner analog parameter fixedly allocated to the temperature sensor by the system
and cannot be modified by the user.
1-4: are allocated to the voltage sensor by default.
1 indicates number 0 -48 V input.
2 indicates the first -48 V input.
3 indicates the second -48 V input.
4 indicates the third -48 V input.
5-8: are user-defined analog parameters for allocating to other extended analog sensors, such as
humidity sensor.
More information:
1. The H303ESC has a built-in humidity sensor. The built-in sensor is located in J5 of the board and
its analog parameter ID is 2. The H303ESC can also be connected to an external humidify sensor
and the connection and configuration methods are the same as what the preceding describes.
Without the built-in humidity sensor, the H304ESC is a simplified H303ESC and must be connected
to an external one.
2. The differences between the H304ESC and the H303ESC are that the LED of the H303ESC is
red and the LED of the H304ESC is green.

The subscriber can get online normally to watch BTV programs and the pictures are

None
n:
After the program is online, the customer’s multicast server sends the IGMP V3 general
s:
query packet in 60 seconds three times. If the multicast server does not receive any
response for these three times, the multicast server considers that the multicast
subscriber is offline, and then disconnects the transmitted multicast stream, causing
service interruption.
In this case, the multicast mode of the MA5600T is IGMP proxy. Because no general
query packet responding to the multicast service is received, it can be determined that
the fault occurs on the MA5600T. To prevent this fault temporarily, we can run a
specified command to periodically send the IGMP report packet to the multicast server.
1. When the multicast service is interrupted, run the display igmp user online all
s:
command to check whether the multicast subscriber is online. It is found that the
subscriber gets offline already.
2. Capture packets on the upstream port. For the captured packets, see the attachment.

general query packet after the program gets online, but the MA5600T does not respond.

In this case, the multicast mode of the MA5600T is IGMP proxy.
3. Because the IGMP version of the MA5600T is IGMP V2, the IGMP V3 general query
packets cannot be identified. Try to rectify this fault by modifying the IGMP version to
IGMP V3. It is found that the fault persists.
4. Through analysis, it is found that this fault can be temporarily prevented by actively
sending general query packets from the MA5600T. Run the following two command:
igmp unsolicited-report interval 30
igmp program add ip 239.255.1.2 bandwidth 15000 unsolicited enable index 1
After these two command are executed, the MA5600 sends the IGMP report packet to
the upper-layer device in each 30 seconds. Thus, this fault can be prevented
temporarily.
Suggestions and
Summary:
Capturing packets on the upstream port and then analyzing them is a basic method of
locating a fault. If we also understand protocols very well, we can locate faults quickly.

Description:
The multicast service is normal, but the picture quality of the program is a little poorer
than that of the competitor and the program has pause point. In addition, the comparison
between the packets captured by the two PCs that are in the place of the two clients
shows that the third fragment of some UDP packets captured by the PC connected to
the MA5600T is discarded. See the attachment for the packet capturing file.
Null
n:
1. The packet capturing file in the feedback from the filed engineer shows that the third
s:
fragment of some UDP packets captured on the client in a certain period is discarded.
Surely, this is the cause of the pause point and what is next is to find out the location in
which this fragment is discarded.
2. Capture packets respectively in three locations of the topology:
①Capture packets on the egress port of Cisco and perform the port mirroring on the
Cisco device. Check the sequence of the packets transmitted from the upper layer
device, analyze the packets (about 10 M) captured from the Cisco router, and find that
the problem of discarded fragment does not occur. Only some multicast UDP packets
with fewer bytes are found , which is not the problem.
②Perform the egress port mirroring on our LSW. Mirror the packets that are transmitted
to the service board to the GIU port and capture packets.
MA5600T(diagnose)%%debugging lswdrv bcm-cli
BCM.0> _Mirror mode=add OutPort=8 ToPort=6
8===>This refers to the egress direction of this GE port on the LSW. The 8 GE port maps
the service board in slot 1
6===>This is to mirror the packet in the egress direction of port 8 to this GE port of the
LSW. The 6GE port maps port 0/20/0 of this uplink board.
Analyze the captured packets (14 M) of the LSW and find that only the fragments of
some two-frame packets are discarded; however, the number of discarded fragments is
very small and this problem may occur only in the case of the multicast server burst.
③Use the PC to capture packets on the modem of our service board and find that the
symptom is the same as that in the feedback. The third fragment of many multicast UDP
packets is discarded. We are sure that the fragment is discarded by either the board or
the modem.

3. Further check the parameters and commands related to the board and find that the
PIR value set for the traffic profile is very small. This may be the root cause of the packet
loss and the poor multicast quality:
//Configure the VCI33 VPI1 multicast service
igmp user add port 0/1/21 adsl 1 33 video 1 33 no-auth quickleave immediate
//The traffic profile of VCI33 VPI1 is rx 9 tx 15

Here, 390/s is the number of frames that pass this GE port in the downstream direction
each second. If each fragment is calculated as 1410 bytes, we can figure out:
390 * 1410 byte = 549900 byte/s > 507904 byte/s. Thus, a large number of packets are
lost.

Q:

How to connect and configure the humidify sensor in the H304ESC?
None
n:
None
A:
s:
As for hardware connection, the H304ESC provides many JTD interfaces and JTA interface.
Where, the JTD interface is used for connecting the digital parameter sensor, and the JTA interface
is used for connecting the analog parameter sensor.
In general, the humidity sensor is an analog parameter sensor. Therefore, it can be connected to
the JTA2 interface.
As for software configuration, see the Command Reference of the corresponding device. The
following shows an example of the command.
huawei(config-if-h304esc-0)#esc analog 6 40 80 0 100 sersor-type :1current unit H name
RoomHumidity
For how to select the analog parameter ID when running this command, see the Command
Reference of the corresponding device. For example, the Command Reference of the MA5600
provides the following description:
0: is the default inner analog parameter fixedly allocated to the temperature sensor by the system
and cannot be modified by the user.
1-4: are allocated to the voltage sensor by default.
1 indicates number 0 -48 V input.
2 indicates the first -48 V input.
3 indicates the second -48 V input.
4 indicates the third -48 V input.
5-8: are user-defined analog parameters for allocating to other extended analog sensors, such as
humidity sensor.
More information:
1. The H303ESC has a built-in humidity sensor. The built-in sensor is located in J5 of the board and
its analog parameter ID is 2. The H303ESC can also be connected to an external humidify sensor
and the connection and configuration methods are the same as what the preceding describes.
Without the built-in humidity sensor, the H304ESC is a simplified H303ESC and must be connected
to an external one.
2. The differences between the H304ESC and the H303ESC are that the LED of the H303ESC is
red and the LED of the H304ESC is green.

1. The 17a and 30a profiles are used in short-haul applications (Generally the distance is
no greater than 300 m). In fact, the 30a profile is rarely used. Currently, the 17a profile is
used in short-haul applications.
2. The 12a, 12b, 8c, and 8d profiles are used in medium-haul applications (generally the
distance is from 300 m to 1 km).
The 8a and 8b profiles are used in long-haul applications (the distance is greater than 1
km). They are compatible with ADSL2 and ADSL2+, and suitable for central offices (The
8a profile can provide a transmit power of 20.5 dBm, the same as in ADSL2+.). The
coverage range can exceed 3 km and is close to the coverage range of ADSL2+.
3. When the distance is greater than 1.5 km, the rate curve of the VDSL2 overlaps with
that of the ADSL2+. In the distance from 1 km to 1.5 km, the rate advantages of the
VDSL2 are not obvious. Therefore, the main coverage range of the VDSL2 is still less
than 1 km.
4. The 12a, 17a, and 30a profiles are especially suitable for short-and-medium-haul
applications, such as FTTN, FTTC, and FTTB. Take the 12aB8-4 as an example. T he
uplink can be at least 10 Mbit/s over a copper cable whose diameter is 0.4 mm within a
distance of 500 m, 5 Mbit/s within a distance of 700 m, and 1 Mbit/s within a distance of 1
km (24 VDSL2 lines with self-crosstalk). The downlink rate can be 30 Mbit/s over a
copper cable whose diameter is 0.4 mm within a distance of 500 m, 20 Mbit/s within a
distance of 700 m, and 18 Mbit/s within a distance of 1 km (24 VDSL2 lines with
self-crosstalk). If the 17a or 30a profile is used, the rate can be 30 Mbit/s or 100 Mbit/s in
the uplink, and 50 Mbit/s or 100 Mbit/s in the downlink within a distance of 300 m.

Cause Analysi
The preceding problem occurs during the actual configuration. For example, the ONT
s:
can go online and the running state is normal after the ONT is added. In this case, the
problem occurs because the actual capability set profile of the ONT is different from the
bound capability set profile or the ONT is faulty.
Handling Proces
1. The parameters in the capability profile set profiles and the device ports of the
s:
MA5680T and the MA5626G are consistent after the onsite comparison. Run the display
ont capability 0 0 command to view the parameters such as the ports and the T-CONTS
of the MA56206G and these parameters are consistent with the parameters of the
MA5680T.
2. View the MA5626G technical manual and find that the MA5626G supports up to 128
GEM ports, but the capability set profile configured on the OLT supports only 32 GEM
ports. Therefore, the parameters of the MA5626G and the OLT are inconsistent and the
matching status is "mismatch".
3. You need not pay attention to the inconsistent parameters because they do not affect
the services.
Suggestions and
Summary:
Although the parameters do not affect the services, the configuration cannot be
delivered to the ONU after the ONU is reset. Run the ont resume resource command. If
the actual ONT capability is inconsistent with the capability set profile bound to the ONT,
exclude the part in the ONT management commands that exceeds the actual hardware
capability based on hardware capability parameters reported by the ONT. In addition,
only the ONT management commands allowed by the ONT hardware capability are
delivered.

Fault symptom: The ringing is normal for the call-in and call-out services of the MA5606T
voice service. The communication, however, is unidirectional. That is, the user can hear
the other party but the other party cannot hear the user. The dialing between the two
internal phones of the MA5606T is normal and the preceding problem does not occur.

2. The processing of the MA5606T or the softswitch is abnormal.
3. The layer 3 route of the bearer network is faulty or certain User Datagram Protocol
(UDP) ports are shielded.
Handling Proces
1. The internal calling is normal. Through the analysis of the captured signaling packets
s:
by running the dbwin command, the signaling exchange between the MA5606T and the
softswitch is normal.
2. Replace the MA5606T with an MA5620G and ensure that all the relevant
configurations are the same. The problem does not occur during the dialing. Therefore,
the softswitch and the bearer network are normal. The problem occurs on the MA5606T.
3. View the configurations of the MA5606T. It is found that the media stream and the
signaling stream pass different gateways. The signaling IP address of the softswitch can
be pinged, but the peer IP address of the Real-Time Protocol (RTP) stream cannot be
pinged. Therefore, the route of the RTP stream is abnormal. Configure a static route for
the media stream on the MA5606T (the next hop is the gateway of the media stream of
the VoIP address pool). Test the communication again, and the problem is solved.
Since the media gateway is configured in the VoIP address pool of the MA5606T and
the communication on the MA5602E with the same configurations is normal, why the
communication is normal only after you configure the static route for the media stream?
Through analysis, the MA5606T (with the MCUA control board) has a media stream
forwarding mode different from that of the MA5620G in the upstream direction. The
media streams of the MA5606T are forwarded through layer 3 and the system routing
table needs to be queried. The media gateway in the VoIP address pool of the MA5606T
can be used only for the turnaround of the RTP stream. This media gateway cannot
function as the actual gateway of the media streams.
Suggestions and
Summary:
In the case of the MA5606T with the MCUA control board, the media gateway in the
VoIP address pool cannot be used as the actual gateway of the media streams.
Therefore, you need to configure the static route or the default route manually to ensure
that the RTP routing is correct.
In the case of the MA5606T with the MCUC control board, you only need to configure
the media gateway in the VoIP address pool. This configuration is the same as the
configuration of the MA5620G.

1. The optical path is faulty. Check the upstream GICF board and switch 6500 of
company C. The ports are set to the 1000 M full-duplex mode forcibly and the optical
port is in the UP state. This indicates that the optical path is normal.
2. The data configuration of the upstream port of the MA5600T is incorrect. Cancel the
link aggregation. The upstream service of a single link is normal. This indicates that the
data configuration of the upstream port of the MA5600T is correct.
3. The configuration of the Link Aggregation Control Protocol (LACP) is incorrect.
Configure aggregation and do not run LACP:

Note: the system at both ends of the LACP static aggregation group link runs LACP, but
the system at both ends of the LACP manual aggregation group link does not run LACP.
Services are normal when LACP is not run. Therefore, it can be determined that the fault
is caused by the LACP interconnection.
4. The configuration of the switch 6500 of company C at the peer end is incorrect.
1. The switch 6500 of company C supports two protocols, that is, Port Aggregation
Control Protocol (PAgP) and LACP, and PAgP is used by default. It is suspected that the
cause of the interconnection failure is that the default PAgP is configured. Check the
configuration with the customer and find that LACP is configured.
2. Run the following commands to configure LACP of the switch 6500 of company C to
be in the active mode:
Router# configure terminal
Router(config)# interface range fastethernet 5/6 -7
Router(config-if)# channel-group 2 mode active
Router(config-if)# end
Check services again and the problem is solved.
Summary: The switch 6500 of company C supports PAgP and LACP. PAgP is patented
by company C and LACP is specified in the IEEE 802.3AD. The default configuration is
PAgP. You can run the set channelprotocol [pagp | lacp] command to change the default
configuration. PAGP uses the standard of company C, but LACP uses the IEEE
standard. Therefore, company C modifies the new SUPERVISOR to support LACP. If
WS-X6K-SUP1A-MSFC or WS-X6K-SUP1A-MSFC2 exists in the show module of switch
6500 of company C, LACP is supported.
LACP of switch 6500 of company C includes two modes:
Passive LACP mode: The port is in the passive state and the active LACP negotiation is
disabled. This mode is used by default.
Active LACP mode: The port is in the active state and the active negotiation is enabled
on this port.
In this case, the customer configures only the LACP mode on the switch 6500 of
company C but does not enable the active negotiation. As a result, the interconnection

between the switch 6500 of company C and MA5600T fails.
Suggestions: When the MA5600T is aggregated upstream to the switch 6500 of
company C, LACP and the active mode must be configured on the switch 6500 of
company C so that the LACP negotiation between the MA5600T and switch 6500 of
company C is enabled. The active negotiation mode is used on Huawei MA5600T by
default.

On the MA5600T of R51, the system configures a T-CONT 0 for each ONT by default
and a fixed 5 Mbit/s bandwidth is used for the OMCI and cannot be changed. For details,
see the FAQ-How to Allocate the Reserved Bandwidth of the MA5680T (ONT) Providing
the GPON Service for the Upstream OMCI.
On the MA5600T of R52 and later versions, the type of T-CONT 0 can be changed to
assured and the minimum bandwidth can be configured to 1 Mbit/s. In the
implementation, each ONT uses T-CONT 0 for the OMCI by default and each T-CONT 0
uses DBA 1 profile, which are applicable to R51 and R52. The DBA 1 profile uses the
fixed 5 Mbit/s bandwidth by default. Therefore, when the MA5600T is upgra ded from
R51 to R52, the configuration does not change and the OMCI uses the fixed 5 Mbit/s
bandwidth by default.
To change the bandwidth and type of T-CONT 0 for the OMCI on the MA5600T of R52,
do as follows:
1. Add a DBA profile, such as profile 10. The type of T-CONT 0 is assured and the
bandwidth of this profile is 1 Mbit/s. Profiles 1-9 are default profiles and cannot be
changed.
2. In the board mode, run the tcont modify-profil command to change the DBA profile
bound to T-CONT 0 to 10. According to the command, this operation is to change the
DBA profiles of ONTs one after another. Therefore, a script must be made to change the
DBA profiles in batches.

ONUs connected to other PON ports of the same GPBC board are normal and the fault
s:
is not caused by the optical path. Therefore, the possible causes of the fault are as
follows:
1. The PON port is faulty.
2. The optical splitter is faulty.
3. The ONU is faulty.
Handling Proces
1. Remove optical fibers that connect optical splitters of the first level to all optical
s:
splitters of the second level and directly connect the ONUs to the optical splitters of the
first level. The ONUs go online normally and are stable.
2. Insert optical fibers that connect optical splitters of the first level to optical splitters of
the second level. After the optical fiber that connects an optical splitter of the first level to
an optical splitter of the second level is inserted, the fault recurs.
3. Check the ONUs connected to the optical splitter of the second level one after
another. After the optical fiber that connects the optical splitter to an ONU is removed,
the fault is rectified.
Suggestions and
Summary:
No exception alarm is generated on such faulty ONU and the fault persists after an ONU
is replaced. Therefore, the fault can be located only by excluding possible causes one
after another.

ALARM NAME : Alarm 2 for MAC layer frame error reach the limit
PARAMETERS : FrameID: 0, SlotID: 1, PortID: 3, ONUID: 0
DESCRIPTION : Alarm 2 for MAC layer frame error reach the limit
CAUSE : MAC layer frame error reach the limit of 1.953125*10E-6
The threshold alarm for the error frames is generated because of the poor qualit y of the
s:
line or the ONT.
1. Query the alarms. It is found that a lot of alarms that the count of the error frames
s:
reaches the threshold are generated on the ONT. Run the display port statistics
command to query the statistics of the port. It is found that the number of the error
packets increases by 200 per second.
After the analysis, it is determined that maybe the problem is caused by the overlarge
optical attenuation or poor ONT quality; however, the distance between the ONT to the
MA5680T is less than 50 meters. Therefore, the line quality should be good.
2. Replace the ONT. It is found that the problem persists.
3. Check the optical path segment by segment. The optical fiber, through primary
splitting, is connected to the suspected ONT from the EPON port. Currently, the EPON
port is connected to only one ONT.

Check the optical splitter. It is found that the fiber in the inbound direction and the fiber in
the outbound direction are both connected to the ingress of the optical splitter.
Connect the fiber in the outbound direction to the egress of the optical splitter. The
problem is solved.
4. The optical splitter has two ingresses, an active one and a standby one. The fibers in
the inbound and outbound directions must be connected to the corresponding ports. The
incorrect connection causes large optical attenuation, thus affecting the service.
Suggestions and
Summary:
When the ONT goes offline frequently, query the alarms and the performance statistics
of the port to find the cause. Then, check the optical path segment by segment to locate
the fault.

s:
A:
s:
The two POTS ports on the ONU (GPON terminal) can be adopted to implement the
VoIP service. The VoIP service is implemented through the built-in IAD of the ONU.
The IAD is an integrated access device specially for the VoIP service. After being
transmitted to the IAD, the analog voice signals are sampled and converted into the
digital signals through the built-in codec chip. Then, the digital signals are transmitted to
the central processing chip for the DSP compression. After the compression, the signals,
in the form of the RTP packets, are transmitted to the IP network.
The IAD, supporting the MGCP protocol, exchanges signaling with the softswitch and
thus implements the VoIP service. The OLT in a GPON network does not process the
VoIP service, but provides the transparent transmission channel.

2. The port of the HG810e is faulty.
Handling Proces
1. Check the ONT profile configured on the MA5680T. The current ONT profile does not

profile providing a GE port. The current ONT profile, however, only provides an FE port.
As a result, after the ONU is powered off, the network port of the PC connected to the
port of the ONU cannot be activated in the auto-negotiation mode, but activated only
after set to the 100 M full-duplex mode forcibly.
2. Run the following command to reconfigure the capability set profile of an ONT
connected to the EPON port and bind the profile to the ONT. That is, the profile matching
the capability attribute of the ONT can be specified.

- Physically checked the SDH and felt very high temperature of SDH and its cards panel.
- Ask transmission engineer to check card health. High temperature alarm found at EFS card and
SDH.
- removed the SDH on transmission engineer instructions and removed the EFS card.
- EFS card was extremly hot. We keep it under room temperature for half an hour and let its temp
erature normalized.
- Also removed the fans plate of SDH and cleaned. Reinstall the fan flate and found that 2 out of t
hree fans started working.
- Installed the EFS card when it cooled to normal temperature and ask Transmission engineer to c
heck EFS card. He reported that card is normal.
- Check the IPMA card and ping the BRAS, BRAS is successfully connected.
- Check the subscribers state, subscribers are using ADSL service smoothly.
- SDH FAN alarms should not be neglected. It can be service effecting, if ignored. Also, it can da
mage the cards as well.
- Temperature alarms of equipments should also not ignored.

Multicast, traffic restriction
Multicast, traffic restriction
two different problems were observed on SIP trunks
1.Call connects and the peer switch sends us SIP acknowedge request, but our switch
do not accept it and the call drops after about ~33 seconds.
2.we send INVITE SDP and offers the codecs in responce the peer switch sends OK
SDP (g711A)but our switch does not sends them ACK rather it sends 6 more INVITE
messages & after 7 conteneous INVITE the session closed and call do not connected.
Null.
Multicast streams are copied on logics. The total traffic of logics and chip 251 is restricted to 1
Gbit/s and 512 (16 x 32) subscribers can be connected to one chip 251.If all 461 subscribers are
connected to one chip 251, the traffic is 2849.4 (5.4 x 461) Mbit/s, which is larger than the traffic
restriction. As a result, packet loss and erratic display occur.
Handling
Process:
Suggestions
and summary:
If the program stream is 5.4 Mbit/s, a maximum of 185 subscribers connected to one chip 251
can watch the program normally. The system supports a maximum of 370 (185 x 2) subscribers
who can watch the program normally. The maximum number of subscribers is (1000/bandwidth
occupied by each program stream) x 2. Reduce the bandwidth of the program stream to 2 Mbit/s
(1000/2 = 500 subscribers) and conduct a test. As a result, the multicast stream can be copied to
all STBs.
The traffic of the UA5000 is restricted. In services with large traffic such as the open multicast,
services may be affected when the traffic exceeds the total traffic restriction. This performance of
the device helps test and troubleshooting in daily maintenance.

In the preceding networking mode, the inband NMS and services fail in the UA5000 office, while
the inband NMS and services are normal in the MA5100 office.
Null.
Possible causes are as follows:
1. The data configuration of the UA5000 is incorrect.
2. The data configuration of the MA5100 is incorrect.
3. The data configuration of the MA5200G is incorrect.
1. Check the data configuration of the UA5000 and MA5100. The data configuration is correct.
Check the data configuration of the MA5200G. The data is the same as that of terminating
MA5100 and UA5000 services.
2. Perform port mirroring on the LAND board of the MA5100, ping the IP address of the
MA5200G from the UA5000, ping the IP address of the UA5000 from the MA5200G, and
capture packets during ping operations.
3. Analyze the capture packets and it is found that the original MAC address in the ICMP packets
sent by the MA5200G is 00-00-00-00-00-00. The UA5000 regards the MAC address as being
illegal, discards the packet, and does not send a response to the MA5200G. Thus, the service
fails.
4. Confirm with MA5200G technical support engineers and know that the MAC address of all 0s
is the MAC address of the VE interface of the MA5200G. Log in to the MA5200G and view
related configuration of the VE interface. You can find that the VE interface is not configured
with the MAC address. Set an MAC address that does not consist of all 0s for the VE interface of
the MA5200G, and then ping the IP addresses of the MA5200G and UA5000. The ping
operations succeed.
5. In the uplink direction, the UA5000 sends the message to the MA5200G through the MA5100,
the inband NMS on the MA5200G adopts IPoEoA service encapsulation mode. Services are
transmitted over PPPoEoA, and the VE interface must be bound to the MA5200G. The difference
between the UA5000 and the MA5100 is that the UA5000 adds MAC address anti-spoofing.
Therefore, the services of the MA5100 are normal while those of the UA5000 fail.
Suggestions
and summary:
When services fail, but data configuration is correct, capturing packets for analysis is the most
effective way to locate the fault.

error 678
The UA5000 version is UA5000IPMBV100R013C03B032SP02, the UA5000 is connected
upstream through the FE port, and the path is IPMB - SDH - OSN3500 - 6650 - MA5200G. This
office is already in service for half a year but the problem that error 678 is prompted during the
dialup of all subscribers occurs at the interval of about one month. Reset the IPMB control board
but the fault persists. After the entire shelf is powered off, the dialup is normal sometimes.
Error 678 is prompted during the dialup of all broadband subscribers.
1. Because the dialup is normal after the entire shelf is powered off and the check at the moment
shows that the IPMB uplink port is normal, the IPMB control board or O2FN daughter board
may be faulty.
2. Because the upper-layer device needs to perform the flexible QinQ processing, the data of the
upper-layer device may have problems.
1. Because the dialup is normal after the entire shelf is powered off and the check at the moment
shows that the IPMB uplink port is normal, the IPMB control board or O2FN daughter board
may be faulty. Replace IPMB and the O2FN daughter board, and the dialup is normal for several
minutes. After IPMB is powered off again, however, error 678 is prompted again during the
dialup. This indicates that the UA5000 is normal.
2. The data of the upper-layer device may have problems. Use a switch to perform the test on site
and the dialup is normal each time. This indicates that the upper layer is normal.
3. Check the networking for IPMB and the switch and it is found that only one cable is replaced.
Then, check the uplink network cable of IPMB and it is found that the wire sequence of the
network cable is incorrect. Replace the cable with another straight through cable and then test the
service, and the service is normal. Then, power off IPMB, test the service, and the service is
normal.
Suggestions
and summary:
The wire sequence at both ends of the straight through cable is
"white-orange-orange-white-green-green-white-blue-blue-white-blown-blown", which does not
comply with the standard of the straight through cable.
Because in this kind of problem, the number of upper-layer devices is large, the problem should
be located one segment by one segment.

ADVICE : No need to proceed"
1. Telnet to affected UA5000. The cpu occupancy in slot 0/3 was sitting at 63% at one instance.
Ping the vlanif IP from NMS has some packet loss. Telnet session got interrupted and need to rest
art.
The packet loss issue is intermittent. The disconnection experienced was due to the packet loss
– there maybe a period of up to 1 minute where the UA5000 will not reply to any pings.
2. There were some transmitted multicast frames and oversized frames on the uplink GE port 0/3
/0 and the frames seem to be rather high.
3. There is also a duplicated mac-address accosiated with slot 3 and slot 6. The duplicated mac-a
ddress is their BRAS mac-address.
4. If the BRAS mac-address has been learnt by the CPE port, this phenomena is not normal. It co
uld cause mac-addresses "drifting" and create network instability.
There are generally two conditions causing BRAS mac-address learnt by user CPE port: (1) Us
er attack. User CPE attempts to send “attacking” packets with the upper-layer BRAS, (2) There e
xists a “ring” or “loop” the customer network.

The host is IPMA. For details on the networking, see the attachment.
Two video terminals, phone 1 and phone 2, are connected to two ADSL terminals respectively,
which are connected to the upstream NE20 router through the APMB board. The services of the
router go upstream to the IP network, to which video terminal phone 3 is connected directly.
Phone 1 and phone 3 can communicate with each other successfully and the video display is
smooth. Phone 2 and phone 3 can also communicate with each other successfully. The
communication between phone 1 and phone 2, however, is abnormal. The screen usually freezes
and erratic display occurs.
Error 678 is prompted during the dialup of all broadband subscribers.
The possible causes may be:
1. The communication between the users of the same board is abnormal.
2. The configuration of IPMA is improper, which causes abnormal communication between the
two users of IPMA.
3. The upstream ports of the users are not consistent.
4. The forwarding of the upper layer NE20 router is abnormal.

and summary:
1. Configure phone 1 and phone 2 on different ADSL service boards respectively and perform
tests. The fault persists.
2. Check the upstream port configuration. It is confirmed that the bandwidth of the upstream port
is sufficient.
3. Perform tests in the lab. The two IPMA users can communicate with each other normally. The
fault in the field cannot be simulated in the lab.
4. Capture packets on the upstream port of IPMA for the normal communication and for the
abnormal communication. It is found that the inbound and outbound packets of IPMA are normal
in the case of normal communication. In the case of abnormal communication, however, the
inbound packets of IPMA are intermittent, which indicates that the forwarding of the NE20 is
abnormal.
5. Upon confirmation with the R&D department, it is found that only one interface is configured
on the NE20 for connecting to IPMA. Under such a configuration, the forwarding efficiency is
abnormal. Different interfaces should be configured for different VLANs for processing different
traffic streams.
6. Modify the configuration on both the NE20 and IPMA and then perform tests. The problem is
solved.
Certain problems that possibly seem to be caused by the UA5000 are actually not caused by the
UA5000. In the case of such problems, the problem should be located by capturing packets on the
upstream port or by performing certain tests. In this way, it can be determined more quickly
whether the problem is caused by the UA5000 or by other devices.

The IPMB board communicates with the upstream MA5680T through the EP1A but the upstream
port on the IPMB is always offline.
NO
The IPMB upstream port can automatically communicate with the EP1A only when the port is an
optical port or when no subboard is configured.
1. Consult the configuration guide. The upstream communication of the IPMB through the EP1A
is self-negotiated. No manual configuration is required.
2. Connect an Ethernet cable directly from the IPMB to the Ethernet port of the EP1A. Both the
EP1A and IPMB ports are normal.
3. A backplane interface fault is suspected. But the same fault occurs to several UA5000 systems
in the field.
4. Consult related engineers. It is found that if an electrical subboard is configured on the IPMB,
the upstream communication goes only through an Ethernet port if in the default mode. The
upstream services cannot go through the backplane interface.

Port 0 is incorrectly configured as an optical port. Run the command
mode 0 GE-Electrical to modify the mode of port 0 to GE electrical. Test the port again.
The port is still not activated.
4. Consult the switch side. The peer end is a 100M electrical port. In the IPM mode, run
the following command:
huawei(config-if-ipm-0/2)#speed
{ portid<U><0,15> }:0
{ 10<K>|100<K>|1000<K> }:100
Command:
speed 0 100
Port 0 is modified to a 100M electrical port. Test the port again. The port is activated.
Suggestions
and summary:
By default, the upstream port of the IPMD board is a GE optical port. In practice, if a 100M
optical port or electrical port is used for upstream communication, the port mode of the IPMD
board must be modified.

In a UA5000R17C02B107 site, captured packets show that the AG does not receive reply
messages from the softswitch when packet loss occurs in the network. As a result, the AG does
not retransmit the lost packets.

A difference exists in this UA5000 version from earlier versions. In addition to TCP and UDP,
the parameter alf/udp is added in this version. In this version, to enable H.248 retransmission,
the alf/udp attribute must be selected, while in other versions, the conventional configuration is
UDP where the retransmission mechanism is also effective.

The default negotiation start version of this UA5000 is V3, while, according to softswitch
engineers, the H.248 negotiation version on the softswitch side is V2. Modify the negotiation

0: negotiate based on profile
1: start negotiation from V1
2: start negotiation from V2
3: start negotiation from V3
The fault is rectified.
In this UA5000 system, MG interface negotiation starts from V3 by default. This parameter
must be modified manually.

An H.248 related problem can be handled by starting with signaling analysis. It is necessary to
have certain knowledge of the H.248 protocol.

However, because of the presence of [0-9].L, where "." indicates unlimited repetition of the
dialing event before ".". The timer after "." is a long timer. According to the H.248
specifications, when the long timer conflicts with the short timer, the long timer prevails. The
long timer is therefore activated.
3. Delete the [0-9].L dialing rule and perform the test again. The short timer is effective.

ss:
interface can register successfully and the system does not have abnormal alarm information.
2. Run the display runstat callInfo command to query the current call information in the system.
It is found the off-hook quantity is 50 and the communication quantity is 5. The put-through rate
is very low.
3. Check and replace the control board and its subboard (H601PVMC0+H602ETCN). The
problem persists.
4. Run the display mgc-overload-control command to check the maximum leak rate. It is found
that the value generated by the upgrade tool is 0.40. Change it to 40. The problem persists.
5. Run the DBWIN command to check the maximum leak rate that takes effect in the system
(case attachment: How to Check the Valid Leak Rate of the UA5000). It is found that the
parameter does not take effect. Reset the H248 interface and test the service again. It is found
that the service is normal.
Suggestions and
Summary:
Maximum leak rate is used to restrict the number of calls initiated per second. In the subsequent
UA5000 R13C05 and R17 versions, this overload control parameter is added. This parameter
may be abnormal if the upgrade tool is faulty.
In the future, the upgrade tool will be updated to thoroughly solve this problem. Currently,
manually change this overload control parameter after using the upgrade tool.

Null
on:
The household alarm system automatically dials the alarm center through the household
s:
telephone line, and transmits related instructions to the alarm center through the DTMF signals.
In this manner, the automatic alarm function is implemented.
After the phone carrier is replaced, the household alarm cannot work in the normal state. First,
we should confirm in which phase the problem occurs: dialing phase, connection phase, or
conversation phase. Then, we can determine which phase is abnormal.
According to the standard document NICC1704 of country Y, the household alarm adopts the
Fast Format Protocol and DTMF signals to transmit messages, which lays a high requirement on
call channel delay. Carrier C, however, is a new carrier that provides the VoIP-based voice
service. The call channel delay from the terminal user to the server on the PSTN network may
be large. The call channel delay is suspected to some extent.
Handling Proce
After the problem recurs on site, use a recording pen to record the voice on the line. After
ss:
analyzing the recorded voice, do as follows:
1) According to the recorded voice, the problem occurs in the conversation phase.
2) Use the Cooledit to view the waveform of the recorded voice, and compare it with the
corresponding standard (see the attachment). It is found that when the problem occurs, the ACK
message (1.4 kHz single audio) sent from the alarm has a large delay. As a result, the server
considers that the ACK message is not received in time and considers the alarm failure.
3) In the MSAN, the adjustable parameters that affect the delay are jitter buffer and packet
disassembly duration. In the current version, jitter buffer is dynamically adjusted according to
the network quality. Changing jitter buffer may not make a difference. The packet assembly
duration, however, is set by the softswitch. Currently, the packet assembly duration is set to 20
ms instead of 10 ms recommended by NICC.
4) Change jitter buffer to 20 ms. It is found that the problem persists. Restore jitter buffer to its
default value and change the packet assembly duration from 20 ms to 10 ms. Then the alarm
works in the normal state. According to the waveform, the protocol is complied with.
5) After tests for several times, it is confirmed that the packet assembly duration is the key factor
that affects the alarm. After the packet assembly duration is changed from 20 ms to 10 ms, the
problem is completely solved.

A UA5000R13C02B032 is deployed under a softswitch. Subscribers often complain that no tone
is displayed upon off hook.
Null
on:
1. The network quality is poor.
s:
2. The softswitch does not send the dial tine event correctly.
3. The AG processes H.248 signaling incorrectly.
Handling Proce
1. Send 1000 ping packet from the AG to the softswitch. No packet is lost and the delay is
ss:
stable.
2. Capture packets on the softswitch and the AG simultaneously and compare the signaling
messages.
Signaling captured on the AG:
When the fault occurs, the AG reports offhook and the softswitch sends a dial tone event as
cg/dtu instead of cg/dt. Because cg/dtu is not an H.248 descriptor. The AG cannot identify it and
therefore does not send the dial tone. Because no response is received from the AG, the
softswitch sends five Modify messages to send the dial tone.
Signaling on the softswitch:
The softswitch sends five Modify message continuously to the AG to send the dial tone after a
subscriber hooks off. The dial tone event is cg/dt. Because the AG does not respond, the
softswitch starts the retransmission mechanism and stops sending messages after sending the
message for five times.
But why signaling captured on the softswitch is different from that captured on the AG. On the
AG side, packets are captured by an Ethereal capturer and the dial tone event captured is cg/dtu.
On the softswitch side, packets are captured by the network management application and the
dial tone event captured is cg/dt. Because of modular design, different modules of the softswitch
system accomplish different functions. The signaling capture on the softswitch is signaling of
the protocol processing module. That this signaling is normal does not mean the signaling sent
from the softswitch is normal.
By tracing the Debug message, the softswitch engineer finds that the HSCI is faulty so that error
packets are delivered. Replace the HSCI board. The fault is rectified.
Detailed signaling and analysis are described in the attachment.
Suggestions and
Summary:
For an inter-product fault (related to the softswitch and the bearer network), it is necessary to
capture packets on both sides simultaneously to find which product is faulty.

Detect ARP attack from MAC 0011-43ba-c24f, VLAN: 993, GigabitEthernet6/2/4 !
Where, 0011-43ba-c24f is the MAC address of the N2000 BMS. It can be judged that the 8505
switch considers the N2000 BMS as an exceptional attack user by mistake (the N2000 BMS
broadcasts a large number of ARP packets to obtain the MAC address of DSLAM device during
the resynchronization with the 8505 switch). In this way, the 8505 switch does not forward the
MAC address of the N2000 BMS, and places it into the black hole instead. As a result, all ARP
packets are discarded by the 8505 switch. In this case, when you ping the 8505 switch from the
N2000 BMS, the packets are lost and eventually the ping operation fails (however, you can ping
through other PCs under the 2403 switch). Therefore, the N2000 BMS fails to control the device
properly. Configure the anti-attach ARP exclude MAC address on the 8505 switch as follows:
anti-attack arp exclude-mac mac-address (the MAC address of the N2000 BMS). Then the
problem is solved.

To solve the problem of the detachment of NEs from the BMS server, you should consider the
problem from the network perspective and capture packets.

INSTALL control items. No control item for port types and lines is detected.
3. Operations can be performed on devices that are added by using the temporary license,
although the existing commercial license does not authorize ADSL ports. But the client keeps
prompting the license error.
4. After the commercial license is used and the device is added, related modules communicate
with the license center and obtain authorization during the data synchronization of the device.
As the license does not authorize the port types and lines, the N2000 BMS deletes the device
automatically, which causes the problem.
5. When the earlier and later licenses exist at the same time, the error of the license file can be
located according to the following two situations:
1> Check whether the current N2000 BMS replaces the N2000 BMS of versions earlier than
V200R009. If yes, it is possible that the license does not authorize the management capacity.
Ensure that the later license is not used any more on the N2000 BMS. Then submit the later
license to the Notes electronic workflow Platform License and upgrade it to the earlier license.
Obtain the LAC from the electronic workflow, download the earlier license from the license
website, and then consolidate the earlier license with the later one that does not authorize the
management capacity of the device.
2> If the existing N2000 BMS is newly installed, contact the marketing representative and
modify the contract to solve the problem.

Cause Analysi
The N2000 BMS of the office integrates the N2000 BMS and the License Server. Through
s:
alarm analysis of the fsck -y, the system fails to be started because the lv_licese volume of the
License Server cannot be mounted.
Two solutions are available for the problem:
1. Stop the control by the Veritas and make the Solaris start itself. This solution is impossible
because you need to de-encapsulate and unmirror the disks.
2. When the system is started, it mounts the volumes in the /etc/vfstab path automatically.
Therefore, comment out the lv_license volume that cannot be loaded successfully, and then the
system can be started successfully.
Handling Proce
To modify /etc/vfstab, comment out the following line:
ss:
/dev/vx/dsk/n2kdg_N2000Primary/lv_license /dev/vx/rdsk/n2kdg_N2000Primary/ lv_license
/opt/license ufs 2 yes logging
Restart the system, and the standby server can enter the multiuser mode. Mount all the volumes
manually, and synchronize the standby server with the active one. In this case, the N2000 BMS
system can recover.

2. The IP addresses of server A and server B are 10.101.2.205/24 and 10.101.2.206/24. Only
one network port works on each server.
3. Run the WatchmanExplorerV1R2_conf.sh script in the /opt/watchman/server/bin directory to
collect fault information. The fault information file is placed in the /tmp directory.
Note: The WatchmanExplorerV1R2_conf.sh is a new tool on the N2000 BMS
V200R011C02C026 for collecting fault information.
Handling Proce
1. After analyzing the fault information file that is generated by the
ss:
WatchmanExplorerV1R2_conf.sh, R&D engineers confirm that the replication process and
configuration on server A and server B are normal.
2. After the Quick Recover function of the Watchman is enabled on site, the replication relation
between the active server and the standby server returns to normal. The problem is solved.

Summary:
The configuration and operation interface of the Watchman on the N2000 BMS
V200R008B02D061 are greatly different from those on the N2000 BMS V200R011C02C026.
Pay attention to the differences when using different BMS versions.

All the Narrowband NEs Fall out of Management After the N2000 BMS Server Is Restarted
ID: SE0000390510
The N2000 BMS server manages both broadband and narrowband services. After the N2000
BMS server is restarted, broadband NEs can be managed normally, but the narrowband NEs
such as the UA5000 fall out of management and their icons are dimmed. These narrowband NEs
cannot be pinged.

server is restarted. You can infer that the N2000 BMS is not connected after it is restarted.
3. The broadband devices are not affected by the restart. Therefore, you can start with the
difference in the management mode of narrowband devices. Through consultation, you know
that the server is configured in the same network segment as the broadband devices, and that the
narrowband devices in another network segment are managed through static routes.
4. The static routes may be lost during the restart of the N2000 BMS. Configure the static routes
again. The N2000 BMS resumes its management of the narrowband NEs.
Suggestions and
Summary:
The N2000 BMS server can manage both the broadband service and the narrowband service in
different network segments. In this case, the default network card on the server is configured
with an IP address that is in the same network segment as the broadband service. To enable the
server to manage the narrowband service, you should configure static routes from the
narrowband NEs to the server. To prevent loss of routes during the restart of the system, add the
static routes to the start items on the server as follows:
1. Write the following route starting script in the rc3 file in the path /etc on the SUN
workstation: route add network address –netmask subnet mask gateway address.
Example: #route add 192.168.10.0 -netmask 255.255.255.0 10.11.201.254
2. On Windows, write the configured routes mentioned above in a batch processing file (*.bat)
and add them to the start items of the system.

The current N2000 BMS is V200R008B02D061SP27 and the server is a SUN FIRE V440 with solaris 8 and sybase 12.0
Customer needs to migrate this BMS on a SUN FIRE V890.
SUN FIRE V890 server does not work with solaris 8 so, it is necessary to install Solaris 10 and Sybase 12.5
To install Solaris 8 on V890 check OS detail infromation in ".volume.inf"
file in the disk because SUN FIRE V890 supports Solaris 8 just if the
detail version is equal or later than Solaris 8 (02/04) and the CPU is
1050, 1200 or 1350 MHz .
The OS detail informatin was checked in the disk and it was found right
it is Solaris 8 (02/04).
The CPU was checked and it is found that this server has a CPU 1500
MHZ so this new CPU does not support Solaris 8.
