Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with Carrier Sense multiple
access with Collision Detection (CSMA/CD) protocol, and greatly reduced
unnecessary transmission.
This revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port (Full-duplex), which essentially doubled the
bandwidth. Second, by reducing the collision domain to a single switch-port,
which eliminated the need for carrier sensing. Third, by using the
store-and-forward technology’s approach of inspecting each packet to
intercept corrupt or redundant data, switching eliminated unnecessary
transmission that slow the network. By employing address-learning, it
replaced the inefficient receiving port.
Auto-negotiation regulates the speed and duplex operation of each port,
based on the capability of both devices. Flow-control allows transmission
from a 100Mbps node to a 10Mbps node without loss of data.
Auto-negotiation and flow-control may require disablement for some
networking operations that involve legacy equipment. Disabling the
auto-negotiation is accomplished by adjusting the speed or duplex operation
of a port.
Ethernet Switching Technology supplies higher performance at costs lower
than other solutions. Wider bandwidth, no congestion, and the reduction in
network traffic is why the use of an Ethernet switch is replacing expensive
routers and inefficient hubs as the best network solution.

62
5.4.2.2 Advanced
Miscellaneous Settings
MAC Address Age-out Time: Type the number of seconds that an inactive MAC
address remains in the switch's address table. The valid range is 300~765
seconds. Default is 300 seconds.
Max bridge transit delay bound control: Limit the packets queuing time in switch.
If enabled, the packets queued exceeded will be dropped. This valid values are
1sec, 2 sec, 4 sec and off. Default is 1 second.
Broadcast Storm Filter: To configure the broadcast storm control, enable it and
set the upper threshold for individual ports. The threshold is the percentage of the
port's total bandwidth used by broadcast traffic. When broadcast traffic for a port
rises above the threshold you set, broadcast storm control becomes active. The
valid threshold values are 5%, 10%, 15%, 20%, 25% and off.
63
Priority Queue Service settings:
First Come First Service: The sequence of packets sent is dependent on the
arrival order.
All High before Low: The high priority packets sent before low priority packets.
Weighted Round Robin: Select the preference given to packets in the switch's
high-priority queue.
These options represent the number of high priority packets sent before one low
priority packet is sent. For example, 2 High:1 Low means that the switch sends 2
high priority packets before sending 1 low priority packet.
Enable Delay Bound: Limit the low priority packets queuing time in switch.
Default Max Delay Time is 255ms.
If the low priority packet stays in the switch exceeds the Maximum Delay Time, it
will be sent. The valid range is 1~255 ms.
NOTE: Make sure of “Max bridge transit delay bound control” is enabled before
enabling Delay Bound, because the Enable Delay Bound must work under the
“Max bridge transit delay bound control is enabled” situation.
QoS Policy: High Priority Levels: 0~7 priority level can map to high or low queue.
When the VLAN Tag number of a frame is mapping the priority level of the port, this
frame can have a high priority. (This QoS Policy is for the global Switch, not for any
single port)
Protocol Enable Setting:
Enable Spanning Tree Protocol: Default recommended to enable STP
Enable Internet Group Multicast Protocol: enable IGMP protocol
IGMP Query Mode: Recognize different Query from client or server to decide
which Queries will be the first priority, there are three modes to follow:
1. Auto Mode: Choose the indicated Switch, which has the smallest IP address
will be set for the IGMP Query.
2. Enable Mode: Enable one of Switch to be the IGMP Query.
3. Disable Mode: Disable the other CWFE8TX8MS to be the IGMP Query.
64
VLAN Operation Mode:
No VLAN
802.1Q(Tag VLAN) without GVRP VLAN mode
802.1Q(Tag VLAN) with GVRP VLAN mode (Default)
Port Based
Also, the three topologies shown below illustrate how the IGMP Query works
within a network:
1. This topology has to be set for when the switch’s IP address is smaller than
other switch in the subnet.
65
2. This topology has to be set for when the switch’s IP address is not smaller than
other switch in subnet.
Note: This switch supports IGMP protocol, but IGMP function has to be in enable
mode, and the switch has to be the Query.
3. This topology must be set for when the switch’s IP address is not the smallest in
the subnet. If in Auto mode, the network will cause a multi-cast storm from the
client IGMP report, the topology shown below is necessary.
Note: Suggest VOD server set with the switch that has smallest IP address.
66
4. All switches must be in Disable mode when VOD server is set up for IGMP
Query.
GVRP (GARP [Generic Attribute Registration Protocol] VLAN Registration
Protocol)
GVRP allows automatic VLAN configuration between the switch and nodes. If the
switch is connected to a device with GVRP enabled, you can send a GVRP request
using the VID of a VLAN defined on the switch and the switch will automatically
add that device to the existing VLAN.
5.4.3 Console Port Information
1. Console is a standard UART interface to communicate with Serial Port.
User can use windows HyperTerminal program to link the switch. Connect
To->Configure
Baud rate (bits/sec): 9600

5.4.5 Trunking
Trunking provides a standardized means for exchanging information between
Partner Systems on a link to allow their Link Aggregation Control instances to
reach agreement on the identity of the Link Aggregation Group to which the link
belongs, move the link to that Link Aggregation Group, and enable its transmission
and reception functions in an orderly manner. In conclusion, Link aggregation lets
you group up to eight consecutive ports into a single dedicated connection. This
68
feature can expand bandwidth to a device on the network. LACP operation
requires full-duplex mode, more detailed information, refer to IEEE 802.3ad.
5.4.5.1 Aggregator setting
System Priority: A value used to identify the active LACP. The switch with the
lowest value has the highest priority and is selected as the active LACP.
1.Group ID: you can create a link aggregation across two or more ports, choose
the "group id" and click "Get".
2.LACP: If enabled, the group is the LACP static trunking group. If disabled, the
group is the local static trunking group.
All ports support LACP dynamic trunking group. If connecting to the device that
also supports LACP, the LACP dynamic trunking group will be created
automatically.
3. Work ports: The max number of ports that can be aggregated at the same time.
If LACP static trunking group, the exceed ports are on standby and able to
aggregate if the work ports fail. If it is the local static trunking group, the number
must be the same as group ports.
4. Select the ports to join the trunking group
5. If LACP enabled, you can configure LACP Active/Passive status in each port.
6. Select Apply.
69
5.4.5.2 Aggregator Information
When you are setting the LACP aggregator, you can see related information
here.
5.4.5.3 State Activity
Active (select): The port automatically sends LACP protocol packets.
Passive (no select): The port does not automatically sends LACP protocol packets,
and responds only if it receives LACP protocol packets from the opposite device.
1. A link having either two active LACP ports or one active port can perform
dynamic LACP trunking.
A link has two passive LACP ports and will not perform dynamic LACP trunking
because both ports are waiting for the LACP protocol packet from the opposite
device.
2. If you are the active LACP’s actor, when you are selected as the trunking port,
the active status will be created automatically.
70
71
5.4.6 Filter Database
5.4.6.1 IGMP Snooping
The CWFE8TX8MS supports IP multicast, you can enable IGMP protocol on the
web management’s switch setting advanced page, then display the IGMP
snooping information in this page, you can view different multicast groups, VID and
member ports here. IP multicast addresses range from 224.0.0.0 through
239.255.255.255.
The Internet Group Management Protocol (IGMP) is an internal protocol of the
Internet Protocol (IP) suite.
72
IP manages multicast traffic by using the CWFE8TX8MS, routers, and hosts that
support IGMP. Enabling IGMP allows the ports to detect IGMP queries and report
packets and manage IP multicast traffic through the switch. IGMP has three
fundamental types of messages as displayed below:
Message
Description
Query
A message sent from the querier (IGMP router or switch) asking for a
response from each host belonging to the multicast group.
Report
A message sent by a host to the querier to indicate that the host wants to be
or is a member of a given group indicated in the report message.
Leave
Group
A message sent by a host to the querier to indicate that the host has quit to
be a member of a specific multicast group.
5.4.6.2 Static MAC Address
When you add a static MAC address, it remains in the switch's address table,
regardless of whether the device is physically connected to the switch. This saves
the switch from having to re-learn a device's MAC address when the disconnected
or powered-off device is active on the network again.
73
1. To add a static MAC address
2. From the main menu, select administrator, then click Filter Database.
3. Click Static MAC Addresses. In the MAC address box, enter the MAC address
to and from which the port should permanently forward traffic, regardless of the
device's network activity.
4. In the Port Number box, select a port number.
5. If tag-based (IEEE 802.1Q) VLANs are set up on the switch, static addresses are
associated with individual VLANs. Type the VID (tag-based VLANs) to associate
with the MAC address.
6. Click add
5.4.6.3 Port Security
A port in security mode will be “locked” without permission of address learning.
Only the incoming packets with SMAC already existing in the address table can be
forwarded normally. User can disable the port from learning any new MAC
addresses, then use the static MAC addresses screen to define a list of MAC
addresses that can use the secure port. Enter the settings, then select Submit to
apply the changes on this page.
74
5.4.6.4 MAC Filtering
5.4.7 VLAN configuration
A virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain.
It allows you to isolate network traffic so only members of the VLAN receive traffic
from the same VLAN members. Basically, creating a VLAN from a switch is
logically equivalent of reconnecting a group of network devices to another Layer 2
switch. However, all the network devices are still physically plugged into the same
switch.
The CWFE8TX8MS supports port-based and protocol-base VLAN in the web
management page. In the default configuration, VLAN support is enabled and all
ports on the switch belong to default VLAN, and the VID is 1.
NOTE: The default VLAN cannot be deleted.
75
Support Port-based VLANs (IEEE 802.1Q VLAN)
Port-based tagging rule VLAN is an IEEE 802.1Q specification standard. Therefore,
it is possible to create a VLAN across devices from different switch venders. IEEE
802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. This tag
contains a VLAN Identifier (VID) that indicates the VLAN numbers.
Support Protocol-based VLAN
In order for an end station to send packets to different VLANs, it has to be either
capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware
bridge that is capable of classifying and tagging the packet with different VLAN ID
based on not only the default PVID but also other information about the packet,
such as the protocol.
76
5.4.7.1 Basic
Create a VLAN and add tagged member ports to it.
1. From the main menu, click administrator -- VLAN configuration.
2. Click Add
3. Type a name for the new VLAN.
4. Type a VID (between 2-4094). The default is 1.
5. From the available ports box, select the ports to add to the switch and select
Add.
6. Select Apply
5.4.7.2 Port VID
Configure port VID settings
From the main Tag-based (IEEE 802.1Q) VLAN page, click Port VID Settings.
Port VID (PVID)
Sets the Port VLAN ID that will be assigned to untagged traffic on a given port. For
example, if port 9's default PVID is 100, all untagged packets on port 9 will belong
to VLAN 100. The default setting for all ports is VID 1.
77
This feature is useful for accommodating devices that you want to participate in
the VLAN but that do not support tagging. Only one untagged VLAN is allowed per
port.
Ingress Filtering
Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the
port belongs to that VLAN. The CWFE8TX8MS has two ingress filtering rules as
follows:
Ingress Filtering Rule 1: Forward only packets with VID matching this port's
configured VID.
Ingress Filtering Rule 2: Drop Untagged Frame.
78
5.4.8 Spanning Tree
The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D) for
avoiding loops in switched networks. When STP enabled, it ensures that only one
path at a time is active between any two nodes on the network.
You can enable Spanning-Tree Protocol on the web management’s switch setting
advanced item. Select enable Spanning-Tree protocol. ComNet recommends that
you enable STP on all CWFE8TX8MS switches to ensure a single active path on
the network.
1. You can view spanning tree information about the Root Bridge on the
following screen.
79
2. You can view spanning tree status about the switch on the following
screen.
Parameter
Description
Priority
A value used to identify the root bridge. The bridge with the lowest value
has the highest priority and is selected as the root. Enter a number 1
through 65535.
Max Age
The number of seconds a bridge waits without receiving Spanning-Tree
Protocol configuration messages before attempting a reconfiguration.
Enter a number 6 through 40.
Hello Time

The lowest number has the highest priority.
If you change the value, reboot the switch.
Path Cost
Specifies the path cost of the port that the switch uses to
determine which ports are the forwarding ports.
The lowest number is the forwarding port, the range is 1-65535 and
default value base on IEEE802.1D
10Mb/s = 50-600 100Mb/s = 10-60
If you change the value, reboot the switch.
81
5.4.9 Port Mirror
The Port Mirror is a method for monitoring traffic in switched networks. Traffic
through ports can be monitored by one specific port. That is, the traffic that goes
in or out of monitored ports will be duplicated into the mirror port.
Roving Analysis State: Enable or disable the port mirror function.
Mirror Ports: The ports you want to mirror. All mirror port traffic will be copied to a
mirror port. You can select max 8 monitor ports in the switch. If you want to disable
the function, you must set monitor port to none.
Monitor Rx: Monitored receive frames from the port.
Monitor Tx: Monitored send frames from the port.
82
5.4.10 SNMP
Any Network Management running the simple Network Management Protocol
(SNMP) can manage the switch, provided the Management Information Base (MIB)
is installed correctly on the management station. The SNMP is a protocol that
governs the transfer of information between management and agent. The
CWFE8TX8MS supports SNMP V1.
1. Use this page to define the management stations as trap managers and to enter
SNMP community strings. The user can also define a name, location, and
contact person for the switch. Fill in the system options data, then select Apply
to update the changes on this page

Problem Solving
This section is intended to help you solve the most common problems on the
CWFE8TX8MS managed Ethernet switch.
Incorrect connections
Faulty or loose cables
Look for loose or obviously faulty connections. If they appear to be connected,
make sure the connections are snug. If that does not correct the problem, try
a different cable.
Non-standard cables
Non-standard and incorrect wired cables may cause numerous network
collisions and other network problems, and can seriously impair network
performance. A category 5 cable tester is a recommended tool for every
100Base-T network installation.
Improper Network Topologies
It is important to make sure that you have a valid network topology. Common
topology faults include excessive cable length and too many repeaters (hubs)
between end nodes. In addition, you should make sure that your network
topology contains no data path loops. Between any two ends nodes, there
should be only one active cabling path at any time. Data path loops will cause
broadcast storms that will severely impact your network performance.
89
Diagnostic LED Indicators
The switch can be easily monitored through panel indicators to assist in
identifying problems, which describes common problems you may encounter
and where you can find possible solutions.
If the power indicator does not turn on when the power cord is plugged in, you
may have a problem with power outlet, or power cord. However, if the switch
powers off after running for a period of time, check for loose power
connections, power losses or surges at the power outlet. If you still cannot
resolve the problem, contact your local dealer for assistance.
Cables
RJ45 ports: Use unshielded twisted-pair (UTP) or shield twisted-pair ( STP )
cable for RJ45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps
connections or 100Ω Category 5 cable for 100Mbps connections. Also be
sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
