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.
