switch vlan

This command assigns ports as members of a Virtual LAN (VLAN). The

ports can be any of the LAN switch ports. The ports can be the WAN port or

any of the LAN switch ports. Switching is confined to the members of

VLANs.

Packets can be transmitted tagged with the VLAN ID for VLAN trunking or

untagged as follow:

z Tagged ports transmit tagged packets. A port can belong to multiple

VLANs as tagged.

z Untagged ports transmit untagged packets. A port can belong to only

one VLAN as untagged.

Untagged packets delivered to an untagged port are internally tagged with

the VLAN ID to which the port belongs; this enables those packets to be

switched.

Tagged packets arriving at a port, including a VLAN identifier different than

the one of the port, are dropped.

IEEE 802.1p packets are considered untagged packets.

Syntax config switch vlan <vid> name <name> p1|p2|p3|p4 [*|u|t]

Parameters vid Enter the VLAN identification number. Valid

range is 1-4094.

name <name> Enter a name or description of the VLAN. Up to

32 characters are allowed.

p1|p2|p3|p4 *|u|t Enter the VLAN state of the port. * is not

member, U is member and untagged, T is

member and tagged.

Example The following example assigns port 1 to VLAN 3 as an untagged port.
