Defining VLAN Port Assignments

Enabling/Disabling the VLAN Administrative Status

To enable or disable the administrative status for an existing VLAN, enter vlan followed by an existing
VLAN ID and either enable or disable.
-> vlan 755 disable
-> vlan 255 enable
When the administrative status for a VLAN is disabled, VLAN port assignments are retained but traffic is
not forwarded on these ports. If any rules were defined for the VLAN, they are also retained and continue
to classify mobile port traffic. See

Modifying the VLAN Description

To change the description for a VLAN, enter vlan followed by an existing VLAN ID and the keyword
name followed by the new description (up to 32 characters). For example, the following command
changes the description for VLAN 455 to "Marketing IP Network":
-> vlan 455 name "Marketing IP Network"
Note that quotation marks are required if the description consists of multiple words separated by spaces. If
the description consists of only one word or words are separated by another character, such as a hyphen,
then quotes are not required. For example,
-> vlan 455 name Marketing-IP-Network
Defining VLAN Port Assignments
Alcatel switches support static and dynamic assignment of physical switch ports to a VLAN. Regardless of
how a port is assigned to a VLAN, once the assignment occurs, a VLAN port association (VPA) is created
and tracked by VLAN management software on each switch. To view current VLAN port assignments in
the switch configuration, use the
Methods for statically assigning ports to VLANs include the following:

the switch to bridge traffic for multiple VLANs over one physical port connection. (See

Configuring ports as members of a link aggregate that is assigned to a configured default VLAN. (See

Dynamic assignment applies only to mobile ports. When traffic is received on a mobile port, the packets
are classified using one of the following methods to automatically determine VLAN assignment (see
