Static Virtual LANs (VLANs)

Configuring VLANs

For example, to reconfigure the switch to allow 10 VLANs:

Note that you can execute these three steps at another time.

Changing the Primary VLAN. In the default VLAN configuration, the port- based default VLAN (DEFAULT_VLAN) is the Primary VLAN. However, you can reassign the Primary VLAN to any port-based, static VLAN on the switch. (For more on the Primary VLAN, refer to “The Primary VLAN” on page 2-45.)To identify the current Primary VLAN and list the available VLANs and their respective VIDs, use show vlans.

Syntax: primary-vlan< vid ascii-name-string >

Reassigns the Primary VLAN function. Re-assignment must be to an existing, port-based, static VLAN. (The switch will not reassign the Primary VLAN function to a protocol VLAN.) If you re-assign the Primary VLAN to a non-default VLAN, you cannot later delete that VLAN from the switch until you again re-assign the Primary VLAN to another port-based, static VLAN.

For example, if you wanted to reassign the Primary VLAN to VLAN 22 and rename the VLAN with “22-Primary” and display the result:

Reassigns the

Primary VLAN to

VLAN 22.

Renames VLAN 22 to “22-Primary”.
