v. Port Management

Page 15

(a) Destination port: Theoretically it’s possible to set more than one

destination port in a network. Actually the port mirroring function will

lower the network throughput, and therefore it’s recommended to

set ”only one” destination port in a network.

(b) Source port: the traffic source that will be copied to the destination port.

 Disable: means this function is disabled.  Rx: means copy the incoming packets of the selected source port to

the selected destination port.

 Tx: means copy the outgoing packets of the selected source port to

the selected destination port.

 Tx & Rx: means the combination of Tx and Rx.

Take the following configuration as an example. (a) Destination Port: Port 9 ~Port 12 (b) Source port: Port 1 ~ Port 4 (c) Mirrored method: Rx This means all packets received at port 1 ~port 4 will be copied to port 9, port 10, port 11 and port 12. Care should be taken that the more source ports and destination ports is set, the lower network throughput is available for normal traffic.

* Bandwidth Control

This page allows the setting of the bandwidth for each port. The Tx rate and Rx rate can be filled with the number ranging from 1 to 255. This number should be multiplied by the selected bandwidth resolution to get the actual bandwidth.

Page 16

In the “Low” mode, the Tx/Rx bandwidth resolution is 32Kbps for port 1~ port 26. In the “High” mode, the Tx/Rx bandwidth resolution is 256Kbps for port 1 ~ port 24, and 2048Kbps for port 25, port 26.

(a) Low bandwidth for TX

Example 1: The TX number of the port1~4 is set to 10, 20, 30, 40 respectively, and Speed base is set to “Low”. The real bandwidth comes from the formula of 32Kbps*10, 32Kbps*20, 32Kbps*30 and 32Kbps*40 respectively. After the “Update” button is executed, the real bandwidth will show up in TX fields.

(b) High bandwidth for TX

Example 2: The TX number of the port1~4 is set to 10, 20, 30, 40

respectively, and Speed base is set to “High”. The real bandwidth

comes from the formula of 256Kbps*10, 256Kbps*20, 256Kbps*30 and 256Kbps*40 respectively. After the “Update” button is executed, the real bandwidth will show up in TX fields.

Example 3: The RX bandwidth number of the port 5~ port 8 is set to 50, 60, 70, 80 respectively, and Speed base is set to “Low”. The real bandwidth comes from the formula of 32Kbps*50, 32Kbps*60,

Page 17

32Kbps*70 and 32Kbps*80 respectively. After the “Update” button is executed, the real bandwidth will show up in RX fields.

(d) High bandwidth for RX

Example 4: The RX bandwidth number of the port 5~ port 8 is set to 50, 60, 70, 80 respectively, and Speed base is set to “High”.

The real bandwidth comes from the formula of 256Kbps*50, 256Kbps*60, 256Kbps*70 and 256Kbps*80 respectively. After the “Update” button is executed, the real bandwidth will show up in RX fields.

The limitation of the bandwidth control  The actual bandwidth should be less than link speed of the port.

100Mbps link speed for port 25 and port 26, the bandwidth setting should be less than 48 if the bandwidth is set to “High”. 10Mbps link speed for port 25 and port 26, the bandwidth setting should be less than 4 if the bandwidth base is set to “High”. 10Mbps link speed for port 1 ~ port 24, the bandwidth setting should be less than 39 if the bandwidth base is set to “High”.

 Setting the bandwidth to “0” will make the switch running at the “Full

Speed”.

* Broadcast Storm Control

The broadcast storm control is used to block the excessive broadcast packets received during the specified time unit. The valid number ranges from 1 to 63.

The broadcast packet is only checked at the selected port and the number of broadcast packets is counted in every time unit. There are 3 options for the selection of the time unit, as the figure shown above. Once the broadcast storm protection is enabled, the excessive broadcast packet will be discarded. For those broadcast packets incoming from the un-selected port, the switch treats it as the normal traffic.

Page 18

* VLAN mode

The smart switch supports two VLAN modes, tag based and port based. Only one VLAN mode can be enabled at one time.

When the tag based VLAN is selected, the administrator can define the handling method of a VLAN tag to the specified port, including “Add Tag”, “don’t care” or “Remove Tag”. Add tag/Don’t Care/Remove tag definitions are as follows. “Add Tag” means the outgoing packet should contain a 802.1Q tag.

 The 802.1Q tag will be inserted to the outgoing packet of the

selected port if the packet received at the source port does not contain 802.1Q tag.

 The original 802.1Q tag will be kept if the source port received a

packet with 802.1Q tag. “Don’t care” means the outgoing packet of the selected port keep the original packet format of the source port. “Remove Tag” means the outgoing packet should not contain a 802.1Q tag.

 The 802.1Q tag of the outgoing packet of the selected port will be

removed if the incoming packet received at the source packet

contains 802.1Q tag.

 The packet format of the source port will be kept if the packet does

not contain the 802.1Q tag. Note: In tag based VLAN mode, adding tag on the port which is used to

configure this switch is not allowed, because some NICs cannot recognize

802.1Q tag.

Example:

Port 1: The 802.1Q tag of every packet outgoing from this port will be removed. Port 4: The 802.1Q tag of every packet outgoing from this port should be included. Other ports: keep every outgoing packet intact.

vi. VLAN Setting

Page 19

* VLAN Member Setting

Port based VLAN

This web page is designed based on the VLAN member of each port. The following examples illustrate how to configure VLAN in this mode. The Table is configuring the port-based VLAN member of each port. When the port received the packets allows only forwarded to the VLAN member of this port. The function for each button shown on this page is displayed below.

Field

Description

 Select the port number which you want to read VLAN

member of this port.

 Press “Read” button

Update

 Select the VLAN member which you want to update.  Press “Update”

LoadDefault

 Press this button to load default VLAN setting.

Example:

(a) Port 1 received packets can only forwarded to port 2, port 3 and port 4. (b) Port 2 received packets, can only forwarded to port 1, port 3, port 4 and port 5. (c) Port 3 received packets, can only forwarded to port 1 and port 2.

Page 20

Tag based VLAN on Port

This web page allows the administrator configure to Tag-based VLAN member of VID table of 32-entry and Port VID(PVID) source index of each Port.

When a tagged packet is received, the Switch compares the tag in the packet with the one defined in the VID table. The setting will be reflected at VLAN MEMBER window.

When an un-tagged packet is received, the Switch searches for the PVID source index. This PVID will be inserted to the received packet and then it will be forwarded to the destination port according to the VLAN membership corresponding to this PVID. The setting will be reflected at Port VID Map window. The function for each button shown on this page is expressed below.

Field

Description

Add a VLAN

Enter a VID, select the VLAN member and click the VID source

port and then enter a group name. Finally press “Add” button to

send this command. The VLAN will be added to the list.

Delete a VLAN

Select a VID and press “Delete” to remove a VLAN.

Modify a VLAN

Select a VID which you want to modify. After the web page shows up, select the VLAN member and VID source port and then press “Update”.

Page 21

Add a VLAN Group

Step 1: Enter VID. The following example shows VID=45 Step 2: Select VLAN member

Step 3: Select the source port corresponds to this VID. You can select more than one port for a VID. Step 4: Press “Add” to add a VLAN group.

Modify a VLAN Group

Step 1: Select/De-select the VLAN ID Step 2: Select/De-select VID source corresponding to this VID

Step 3: Press “Update”

* Multi-to-1 Setting

Multi-to-1 VLAN is used in CPE side of Ethernet-to-the-Home and is

exclusive to VLAN setting on ”VLAN member setting“. In the other words,

once multi-to-1 is set, the previous VLAN setting will be overridden. The “disable port” means the port which will be excluded in this setting. All ports excluded in this setting are treated as the same VLAN group. In the following example, port 3, port 4, port 6, port 7, port 8 and port 9 are excluded in this VLAN Furthermore these ports are treated as the member of other VLAN. All ports which are not specified in this table only communicate with port 1.

Page 22

* Non-Association Port Setting

Create port isolation. When marking 1~9 checkboxes with your mouse, the inter-transmission between port 1~9 will not be permitted but to only connect port 10 which is not marked with its checkbox.

Counter Category

This page provides port counter for each port. There are 4 groups of statistics in total. These 4 categories cannot work simultaneously. Once you change the counter category, the counter will be cleared automatically.

Field

Description

Transmit Packet & Receive Packet

This category shows both the received packet count (excluding the incorrect packet) and the transmitted packet count.

vii. Per Port Counter

Page 23

Collision Count & Transmit Packet

This category shows the packets outgoing from the switch and the count of collision.

Drop Packet & Receive Packet

This category shows the number of received valid packet and the number of dropped packet.

CRC error Packet & Receive Packet

This category shows the received correct packet and received CRC error.

Refresh

Press “Refresh” button will aggregate the number

of the counter for all ports.

Clear

Press “Clear” button will clear all counters.

* Priority Mode

This page allows the administrator to set the scheduling mode for the TX packets at each port.

Field

Description

First-In-First-Out (FIFO)

All output packet are queued to one queue, first comes first out.

All-High-before-Low (Strict priority)

All packets will be assigned to either high priority queue or low priority queue. The low priority packet will not be forwarded until the high priority queue is empty.

Weight-Round-Robin (WRR)

There are 2 priority queues for Weighted-and-round-robin (WRR) mode. When this mode is selected, the traffic will be forwarded according to the number set in each queue. The queue ID has nothing to do with the priority.

Example: If High, Low queue are set to 5, 3, then the traffic at the specific port will go out in the following sequence. 5 packets stored in High queue, 3 packets stored in Low queue, 5 packets stored in High queue, 3 packets stored in Low queue ……

viii. QoS setting

Page 24

* Class of Service Configuration

There are 4 types of CoS for this setting; ie, TCP/UDP port number, IP TOS/DS, 802.1p priority tag and physical port. The administrator can select more than one item for each port.

Please note that if more than one type of CoS is selected, the switch will arrange the packet to the assigned queue according the following priority: TCP/UDP port number the first, IP ToS/DS the second, 802.1p priority tag the third and physical port the last. This means TCP/UDP port number will override other CoS setting.

For 802.1p priority tag, the following table is used to map the 802.1p field to the priory queue.

For IP TOS/DS priority, there are 7 kinds of TOS field can be assigned to High or Low queues. i.e; 6’b101110, 6’b001010, 6’b010010, 6’b011010, 6’b100010, 6’b110000 and 6’b111000.

* Class of Service

The administrator can select the protocol that will be forwarded as the specified mode. There are 3 administrator-defined UDP/TCP port groups and many well-known TCP/UDP ports. The administrator-defined port number may be a range or a specific number, depending on the mask.

The operating theory for all 4 CoS types can be illustrated by the following figure and table. TCP/UDP CoS, IP TOS/DS, 802.1p are global setting for all ports and has no relation with the physical port.

Example: (a) Priority Mode: WRR. High weight=4; Low weight=2 (b) TCP/UDP CoS: P2 FTP =>High queue; P5 SMTP => Low queue

Priory Field

Priority Queue

(d) 802.1p: P2 802.1p = 6(High queue); P5 802.1p =1(Low queue) (e) Physical port: P5=High queue; P2=Low queue

According to the rule described above, the CoS will be executed in the following sequence.

TCP/UDP > TOS/DS > 802.1p > Physical

P 5

P 2

TOS/DS= 6'b010010

802.1p priority = 6

Page 26

2 packets coming from P2; 4 packets coming from P5; 2 packets coming from P2; ……….

If TCP/UDP CoS is disabled, the switch will check TOS/DS CoS.

4 packet coming from P2; 2 packets coming from P5; 4 packets coming from P2; ……..

If TOS/DS CoS is disabled, the switch will check the 802.1p field.

2 packet coming from P2; 4 packets coming from P5; 2 packet coming from P2; ……………..

If only physical port CoS is enabled, the switch only check the physical port CoS.

* MAC Address Binding

This function provides a method for the administrator to specify the relationship between the physical port and the MAC address. Only the packet with specified source MAC address can communicate with other port.

By specifying the MAC address to each port, the network administrator can prevent the unauthorized administrator from accessing the switch. Each port can bind up to 3 MAC addresses.

ix. Security

Page 27

To activate the port binding function, you should enter the correct MAC

address, select the port number, and set the port binding to “Enable” and then press “Update”.

Note: Setting the multicast address to these fields is not allowed. A warning message will show up if you do so.

* TCP/UDP Filter

By selecting the TCP/UDP port, the network administrator can optionally block some specific applications. There are two kinds of protocol filter functions. The ”positive” function makes the switch forward the selected protocol and drop other protocols.

The ”negative” function makes the switch drop the selected protocol and forward other protocols. The protocol is checked at the secure WAN port. And it should be set at the server side.

The figure shown below illustrates how this function is applied to the real environment.

Example: (a) Enable TCP/UDP Filter function. (b) Select “positive” rule. (c) Set port 5 as secure WAN port and select FTP and TELNET as the

filtering protocol.

(d) Place the server of the selected protocol at the secure WAN port.

Hello Time, Max Age and Forwarding Delay

These fields control how this device handles BPDU. The relationship of these fields is listed below.

Note: 2*(Forward Delay-1) >= Max Age, Max Age >= 2*(Hello Time+1)

* STP Port Settings

This web page provides an interface for the administrator to set the STP/RSTP port configuration.

Page 30

Field

Description

Port No.

To configure the parameters of RSTP/STP port, the administrator should select a physical port number, assign a priory number, enter the RPC and then press “Submit” button.

Priority (0~240)

Priority field defines the priority of the RSTP/STP port. The lower the number is, the higher possibility it will become a root port. There is a default value for each port.

RFC (0~200000000)

RPC stands for “Root Path Cost”. The higher the cost is, the lower possibility it become a root path. In the general case, the physical port with the higher bandwidth will be assigned a lower cost.

* Loopback Detection Settings

This web page provides loopback detection function. When loopback detection function is enabled and a port received its own BPDU, the detection agent drops the loopback BPDU and places the interface in discarding mode. This loopback status can be released automatically, if auto wake up function is enabled.

This page is used to set trunk group for load balance and cable link auto-backup. There are 2 methods to set a trunk; i.e. Static and LACP. The meaning of each field shown in the following table is explained as following.

The smart switch supports three trunk groups, which can set port 1 ~ port 8, port25 and port 26, and trunk 1 consists of port 1 ~ port 4, trunk 2 consists of port 5 ~ port 8, trunk 3 consists of port 25, port 26. Trunk hash algorithm can be selected according to 2 different methods.

Link Aggregation

Algorithm

Description

Among the trunk member ports, the packet will be distributed based on the source MAC address.

DA XOR SA

Among the trunk member ports, the packet will be distributed based on the XOR calculation result of the source MAC address and the destination MAC address.

Field

Description

Member

There are three configurable trunk groups. “--“ means the trunk has not been built on the corresponding port. “A” means trunk has been built on the corresponding port.

State

Administrator can enable/disable the function of this trunk.

Type

 Static: Static setting by manual.  LACP: Setting by ACP.

Operation Key

Assign an operation key for this device

Time out

 Short Time Out: Re-configure LACP trunk every 1 second.  Long Time Out: Re-configure LACP trunk every 30 second.

Activity

You should set at least one side of each trunk to “Active” state. If both sides of a trunk are all set to “Passive”, LACP trunk will never

be built up.

* Relay Agent Configuration

This web page allows the administrator to enable/disable DHCP Relay Agent function. In addition, option 82 message is selectable by setting.

Field

Description

DHCP Relay State

Allow the administrator to enable/disable Relay Agent function.

DHCP Relay Hops Count Limit

Specify the maximum number of Relay Agent traveling from DHCP agent to DHCP server.

DHCP Relay Option 82 State

The pre-condition for enabling/disabling this function is that

DHCP Relay State is set to “enable”. Once the Relay State is

set to “enable”, the administrator can enable/disable Option

82, depending on whether the Option 82 information is required.

xii. DHCP Relay Agent

Page 33

* Server IP List

The IP address of DHCP server, which can be relayed by this Relay Agent, should be specified on this web page.

* VLAN to Server IP Map

This web page defines the relationship between the VLAN group and the serve IP address.

Note: One server should belong to only one VLAN ID. If you set the same

server IP address to different VLAN ID, the warning message will show up, as the figure shown below. You can set more than one server IP address in a VLAN ID.

This function provides the administrator with a method to backup/recovery the switch configuration. The administrator can save configuration file to a specified file.

If the administrator wants to recover the original configuration, which is saved at the specified path, just enter the password and then press the “Upload” button. Finally the backup configuration of the switch will be recovered.

The switch will check whether or not the uploaded file is correct. If the content of the uploaded file is incorrect, the switch will show a warning message.

Miscellaneous setting is used to configure Output Queue Aging Time, VLAN Striding, IGMP Snooping and VLAN Uplink.

xiv. Miscellaneous Settings

Page 35

* Output Queue Aging Time

This function is used to avoid the poor utilization of the switch. When a packet is stored in a switch for a long time, the time slot defined by the protocol will expire and this packet becomes useless. To prevent these useless packets from wasting the bandwidth, this switch provides an option to enable the queue aging function. Once enabled, the switch will monitor the aging timer for each packet before it is sent out. The packet which stays inside a queue for a long time will be discarded.

* VLAN Striding

By selecting this function, the switch will forward uni-cast packets to the destination port, no matter whether destination port is in the same VLAN.

* IGMP Snooping

When this function is enabled, the switch will execute IGMP snooping version 1 and version 2 without the intervention of CPU. The IGMP report packets are automatically handled by the switch. When the user enable “Leave packet will be forwarded to IGMP router ports” function. If members want to leave this multicast group, the IGMP leave packet will be forwarded to the router ports.

* VLAN Uplink

In VLAN, the user can define the “Uplink port”. This is normally the port that attached to the uplink router. This feature is similar to the “Router port”.

After that is set, any frame transferred to the other VLAN member is forwarded only out the uplink port.

For example:

Step 1: set port 1, 2 and 3 are the same VLAN; set port 4, 5 and 6 are the

same VLAN.

Step 2: set port 1 is uplink port of Uplink 1, set port 4 is uplink port of Uplink

2, and press “Update” button.

Step 3: If port 2 want to send uni-case packet to port 5. The packet will be

transferred to the port 1.
