and a decimal point is not allowed. The value 0 means auto-logout timer is
disabled. Default: 0

-15-

3.2.2 Ports Configuration

Parameter description:
Mode Set the speed and duplex of the port. Speed/Duplex is comprised of the combina-

tion of speed mode, 10/100/1000Mbps, and duplex mode, full duplex and half
duplex. In Auto Speed mode, no default value. In Forced mode, default value
depends on your setting.

Flow Control There are two modes to choose in flow control, including Enable and Disable. If

flow control is set Enable, both parties can send PAUSE frame to the transmit­ting device(s) if the receiving port is too busy to handle. When it is set Disable,
there will be no flow control in the port. It drops the packet if too much to
handle. Default: Enable

-16-

3.2.3 VLAN Mode Configuration

The switch supports Port-based VLAN and 802.1Q Tag-based VLAN. Support 24 active VLANs and
VLAN ID 1~4094.

Parameter description:
VLAN Mode Disable - Stop VLAN function on the switch. In this mode, no VLAN is applied

to the switch. This is the default setting.
Port-based - Port-based VLAN is defined by port. No filtering criterion applies

in port-based VLAN. The only criterion is the physical port you connect to.
Tag-based - Tag-based VLAN identifies its member by VID. This is quite

different from port-based VLAN. Each tag-based VLAN you built up must be
assigned VLAN name and VLAN ID. Valid VLAN ID is 1-4094.

Metro Mode - The Metro Mode is a quick configuration VLAN environment
method on Port-based VLAN. It will create 22 or 23 Port-based VLAN groups.

Up-link Port This function is enabled only when metro mode is chosen in VLAN mode.

23 - Except Port 23, each port of the switch cannot transmit packets with each
other. Each port groups a VLAN with Port 23, thus, total 23 groups consisting of
2 members are formed.

24 - Except Port 24, each port of the switch cannot transmit packets with each
other. Each port groups a VLAN with Port 24, thus, total 23 groups consisting of
2 members are formed.

23&24 - Except Port 23 and Port 24, each port of the switch cannot transmit
packets with each other. Each port groups a VLAN with Port 23 and Port 24,
thus, total 22 groups consisting of 3 members are formed.

This switch can support up to maximal 24 port-based VLAN groups or 24 Tag VLAN groups.

Management Interface:
State It works when the tag-based mode is chosen. When this function is enabled, only the

tagged packets with this VID can manage the switch.

VID Valid range 1~4094.

-17-

3.2.4 VLAN Group Configuration

It shows the existed information of VLAN Groups List and maintains them, i.e. modify and delete one
of them. You can easily create and delete a VLAN group by pressing <Add Group> and <Delete
Group> function buttons, or click the Group ID directly to edit it.

Parameter description:
ID (Group ID) When you want to edit a VLAN group, you must select the Group ID field.

Then, you will enter Tag-based VLAN Group Setting or Port-based VLAN
Group Setting page, which depends on your VLAN mode selection.

Description The description defined by administrator is associated with a VLAN group.
VID VLAN identifier. Each tag-based VLAN group has a unique VID. It appears

only in tag-based mode.

Member This is used to enable or disable if a port is a member of the new added VLAN,

[Enable] means it is a member of the VLAN. Just tick the check box (t) beside
the port x to enable it.

<Add Group> Create a new port-based VLAN or tag-based VLAN, which depends on the

VLAN mode you choose in VLAN mode function.

Add a Port-based VLAN group

-18-

Add a Tag-based VLAN group

<Delete Group> Just tick the check box (t) beside the ID, then press the <Delete Group> button

to delete the group.

Delete a Port-based VLAN group

Delete a Tag-based VLAN group

-19-

3.2.5 PVID Configuration

This configuration is applied to Tag-based VLAN mode only.

Parameter description:

Port 1-24 Port number.
PVID This PVID range will be 1-4094. Before you set a number x as PVID, you have to

create a Tag-based VLAN group with VID x.

Rule 1 Forward only packets with VID matching this port configured VID. You can apply

Rule 1 as a way to a given port to filter unwanted traffic.

Rule 2 Drop untagged frame. You can configure a given port to accept all frames (Tagged and

Untagged) or just receive tagged frame.
Note: If Rule 1 is enabled and port 1, for example, receives an untagged packet, the

switch will apply the PVID of port 1 to tag this packet, the packet then will be for­warded. But if the PVID of port 1 is not 100, the packet will be dropped.

Tag This is an egress rule of the port. Here you can choose untag or tag. Tag means the

outgoing packets must carry VLAN tag header, just click the check box. Untag means
the outgoing packets carry no VLAN tag header.

Untag State If you checked this function for a Tag out port, the packet form this port may be tag

out. But, the packet would be untag out if the VID of its tag is the same as the value of
Untag VID while Untag VID state is Enable.

Untag VID Valid range is 0~4094.

-20-

3.2.6 Aggregation Configuration

The Aggregation (Port Trunking) Configuration is used to configure the settings of Link Aggregation.
You can bundle more than one port with the same speed, full duplex and the same MAC to be a single
logical port, thus the logical port aggregates the bandwidth of these ports.

Parameter description:

Normal Set up the ports that do not join any aggregation trunking group.
Group 1~8 Group the ports you choose together. Up to 12 ports can be selected for each group.

Note:

Check the following to avoid errors in configuration - When configuring the link aggregation
function, you should check that whether the aggregated ports are in full-duplex mode as well as
their speed is the same or not. The aggregated ports are in the same VLAN group.

-21-

3.2.7 Mirror Configuration

Mirror Configuration is to monitor the traffic of the network. For example, we assume that Port A and
Port B are Sniffer Port and Source Port respectively, thus, the traffic passed by Port B will be copied
to Port A for monitoring.

Parameter description:
Sniffer Mode Used for the activation or deactivation of Port Mirror function, the switch port

mirror supported Ingress traffic only. Default is disable.

Sniffer Port Set up the port for monitoring. Valid port is Port 1~24 and default is Port 1.
Source Port Set up the ports for being monitored. Just tick the check box (t) under the port x

and valid port is Port 1~24.

Note:

When configuring the mirror function, you should avoid setting a port to be a sniffer port and
aggregated port at the same time. It will cause something wrong.

-22-

3.2.8 Quality of Service Configuration

Function description:
Default Class Some packets which did not belong to the selected QoS classifica-

tion method would be classified as Default Class.

[VLAN Tag Priority] In VLAN-tagged packet, there are 3 bits belonging to priority.

According to these 3 bits, we could arrange 8 traffics -0 0 0, 0 0 1, 0
1 0, 0 1 0, 1 0 0, 1 0 1, 1 1 0, 1 1 1. We can set High priority or Low
priority for each traffic class.

[IP ToS Classification] In a received IP packet, TOS field is used to classify the priority

class to which the packet belongs.

[

IP TCP/UDP Port Classification] In a received TCP or UDP packet, the software Port number

associated with the packet is checked and classified for the priority
class. Eight Port numbers can be configured. This option also
supports simple L4 configuration for some popular applications.

[IP Deffserv Classification] In a received IP packet, DiffServ field is used to classify the priority

class to which the packet belongs.

Click one of the QoS classification methods for the switch and click <Apply> to confirm the selection.
Then, click [Configure] for further detailed configuration for the selected classification method.

3.2.8.4 IP Diffserv Classification

IP Diffserve Classification method uses 6-bit field of DSCP in an IP packet to classify the priority class
of the received IP packet. Each DSCP (Diffserv value) can be configured a priority class.

Parameter description:

Diffserv: Display 64 (0~63) DSCP items.
Class: Class assigned to the DSCP

High - High Priority

3.2.9 Bandwidth Management

Bandwidth Management function is used to set up the limit of Ingress and Egress bandwidth for each
port.

Note:

Each port of the switch owns 16KB packet buffer. The packet buffer size will be reduced when
the bandwidth rate limitation is enabled, which may cause that jumbo frame cannot be forwarded.
Avoid enabling jumbo frame and bandwidth rating functions at the same time.

Ingress Rate Limiting parameter description:
Port Number: Choose the port that you would like this function to work on it. Valid range

of the port is 1~24. Multiple port selection is allowed. [All] means all ports
(Port 1 ~ 24).

All T raffic: Set up the limit of Ingress bandwidth for the selected ports. Incoming

traffic will be discarded if the rate exceeds the value you set up in Data
Rate field. Pause frames are also generated if flow control is enabled. The
format of the packet limits to Unicast, broadcast and multicast.

Data Rate (Mbps): Valid range is 0~1000.

Broadcast & Multicasat: Set up the limit of Ingress bandwidth for the port you choose. Incoming

traffic will be discarded if the rate exceeds the value you set up in Data
Rate field. The format of the packet only limits to broadcast and multicast.

Data Rate (Mbps): Valid range is 0~1000.
Egress Rate Limiting parameter description:

All T raffic: Set up the limit of Egress bandwidth for the port you choose. Packet

transmission will be delayed if the rate exceeds the value you set up in
Data Rate field. Traffic may be lost if egress buffers run full. The format
of the packet limits to Unicast, broadcast and multicast.

Data Rate (Mbps): Valid range is 0~1000.
