1. No matter what basis is used to uniquely identify end nodes and assign these nodes VLAN
membership, packets cannot cross VLAN without a network device performing a routing
function between the VLAN.
2. The Managed Switch supports IEEE 802.1Q VLAN. The port untagging function can be used
to remove the 802.1 tag from packet headers to maintain compatibility with devices that are
tag-unaware.
3. The Managed Switch's default is to assign all ports to a single 802.1Q VLAN named
DEFAULT_VLAN. As new VLAN is created, the member ports assigned to the new VLAN will
be removed from the DEFAULT_ VLAN port member list. The DEFAULT_VLAN has a VID =
1.
This section has the following items:
 Management VLAN Configures the management VLAN.
 Create VLAN Creates thn VLAN group.
 Interface Settings Configures mode and PVID on the VLAN port.
 Port to VLAN Configures the VLAN membership.

 Protocol VLAN Group
Setting
Configures the protocol VLAN group.
 Protocol VLAN Port
Setting
Configures the protocol VLAN port setting.
 GVRP Setting Configures GVRP global setting.
 GVRP Port Setting Configurs GVRP port setting.
 GVRP VLAN Display the GVRP VLAN database.
 GVRP Statistics Display the GVRP port statistics.
4.5.2 IEEE 802.1Q VLAN
In large networks, routers are used to isolate broadcast traffic for each subnet into separate domains. This Managed
Switch provides a similar service at Layer 2 by using VLANs to organize any group of network nodes into separate
broadcast domains. VLANs confine broadcast traffic to the originating group, and can eliminate broadcast storms in
large networks. This also provides a more secure and cleaner network environment.
An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the network, but communicate as though
they belong to the same physical segment.
