802.1Q VLAN Configuration
This chapter describes the Enterasys C3 system’s capabilities to implement 802.1Q virtual LANs
(VLANs).
VLAN Configuration Summary
Virtual LANs allow the network administrator to partition network traffic into logical groups and
control the flow of that traffic through the network. Once the traffic and, in effect, the users
creating the traffic, are assigned to a VLAN, then broadcast and multicast traffic is contained
within the VLAN and users can be allowed or denied access to any of the network’s resources.
Also, some or all of the ports on the device can be configured as GVRP ports, which enable frames
received with a particular VLAN ID and protocol to be transmitted on a limited number of ports.
This keeps the traffic associated with a particular VLAN and protocol isolated from the other parts
of the network.
Port String Syntax Used in the CLI
For information on how to designate VLANs and port numbers in the CLI syntax, refer to “Port
String Syntax Used in the CLI” on page 11-1.

configuration is located on the Enterasys Networks web site:

Note: The device can support up to 1024 802.1Q VLANs. The allowable range for VLAN IDs is 1
to 4094. As a default, all ports on the device are assigned to VLAN ID 1, untagged.
