VLAN pooling allows you to associate “equivalent” VLANs to any given service profiles. This feature improves network scalability and reduces broadcast domains across VLANs. This article describes how to configure and apply vlan-pooling in WLC.

VLAN pooling allows you to associate “equivalent” VLANs to any given service profiles. This feature improves network scalability and reduces broadcast domains across VLANs.

VLAN Pools can be applied to the following attributes:

• Users
• User Groups
• MAC Users
• MAC User Groups
• Service Profiles

To configure a VLAN pool, use the following commands:

set vlan-pool pool-name vlan vlan-name

For example, to add the VLANs red and blue to the VLAN pool colors, use the following commands:

WLC# set vlan-pool colors vlan red
success: change accepted.
WLC# set vlan-pool colors vlan blue
success: change accepted.

To remove the VLAN red from the VLAN pool, colors, use the following command:

WLC# clear vlan-pool colors vlan red
success: change accepted.
The VLAN pool is automatically deleted when the last VLAN is deleted from it. You may delete the entire
VLAN pool using the following command:
WLC# clear vlan-pool colors
success: change accepted.

To add the VLAN pool to a MAC user, use the following command:

WLC# set mac-user username attr vlan-name

To remove the VLAN pool attribute from a MAC user, use the following command:

WLC# clear mac-user username attr vlan-name

To add the VLAN pool to a MAC usergroup, use the following command:

WLC# set mac-usergroup name attr vlan-name

To remove the VLAN pool attribute from a MAC usergroup, use the following command:

WLC# clear mac-usergroup name attr vlan-name

To add the VLAN pool to a service profile that affects users on a specific SSID, use the following command:

WLC# set service-profile profile-name attr vlan-name

To remove the VLAN pool from the service profile, use the following command:

WLC# clear service-profile profile-name attr vlan-name

To display information about vlan pools, use the following command.

WLC# show vlan-pool [pool-name]
