2.5.7.2. 802.1Q VLAN

This page, user can create Tag-based VLAN, and enable or disable GVRP protocol.

There are 256 VLAN groups to provide configure. Enable 802.1Q VLAN, the all ports on the switch

belong to default VLAN, VID is 1. The default VLAN can’t be deleted.

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, the switch will automatically add that device to the existing VLAN.

Basic

Create a VLAN and add tagged member ports to it.

1.

From the main menu, click Administrator

Æ

VLAN configuration, click Add then you will see the

page as follow.

2.

Type a name for the new VLAN.

3.

Type a VID (between 2-4094). The default is 1.

4. Choose the protocol type.

We support

802.1v

with the implementation of Port-and-Protocol-based VLAN classification.

User can combine the field “

Protocol Vlan

” and the field of the

port number

to form a new

VLAN group.

NOTE:

IEEE 802.1v provides user to classify the packet through untagged port. There are two possible

strategies of the 802.1v supporting: Port-based VLAN and Port-and-Protocol-based VLAN. We

can support both Port-based VLAN and Port-and-Protocol-based VLAN with our product. User

set the VID to mark the packet from untagged port. Then, the packet can be scheduled by the way

of the IEEE 802.1q.

5.

From the Available ports box, select ports to add to the switch and click “Add >>”. If the trunk

groups exist, you can see it in here (ex: TRK1, TRK2…), and you can configure it is the member

of the VLAN or not.

6.

Click Next. Then you can view the page as follow

Uses this page to set the outgoing frames are VLAN-Tagged frames or no. Then click Apply.

Tag:

outgoing frames with VLAN-Tagged.

Untag:

outgoing frames without VLAN-Tagged.

Port VID

Configure port VID settings

From the main Tag-based (IEEE 802.1Q) VLAN page, click Port VID Settings.

Port VID (PVID)

Set the port VLAN ID that will be assigned to untagged traffic on a given port. This feature is useful

for accommodating devices that you want to participate in the VLAN but that don’t support tagging.

24+2G

switch each port allows user to set one PVID, the range is 1~255, default PVID is 1. The

PVID must as same as the VLAN ID that the port belong to VLAN group, or the untagged traffic will

be dropped.

Ingress Filtering

Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the port belongs to that

VLAN.

24+2G

switch has two ingress filtering rule as follows:

Ingress Filtering Rule 1:

A forward only packet with VID matching this port’s configured VID.

Ingress Filtering Rule 2:

Drop Untagged Frame.

2.5.8. Spanning Tree

The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in

switched networks. Enable STP to ensure that only one path at a time is active between any two nodes

on the network.

You can enable Spanning-Tree Protocol on web management’s switch setting advanced item, select

enable Spanning-Tree protocol. We are recommended that you enable STP on all switches ensures a

single active path on the network.

1.

You can view spanning tree information about the Root Bridge. Such as follow screen.

2.

You can view spanning tree status about the switch. Such as follow screen.
