The Even named VLAN assignment type is only supported in tunnel and decrypt-tunnel modes. It is not supported in
split or bridge modes. It is not allowed for named VLANs that are configured directly under a virtual AP (VAP). It must
only be used under named VLANs. L2 Mobility is not compatible with the existing implementation of the Even named
VLAN assignment type.
6. In the List of VLAN IDs field, enter the VLAN IDs you want to add to this pool. If you know the ID, enter
each ID separated by a comma. You can also click the drop-down list to view the IDs, then select a VLANID
to add it to the pool.
VLAN pooling should not be used with static IP addresses.
7. You must add a VLAN ID to create a named VLAN.
8. When you finish adding all the IDs, click Add. The VLAN name along with assignment type and VLAN IDs
appears on the VLAN Pool window.
9. Click Apply.
10.At the top of the window, click Save Configuration.
Distinguishing Between Even and Hash Assignment Types
The VLAN assignment type determines how the controller handles a VLAN assignment.
The Hash assignment type means that the VLAN assignment is based on the station MAC address. The Even
assignment type is based on an even distribution of named VLANassignments.
The Even named VLANassignment type maintains a dynamic latest usage level of each VLAN ID in the named
VLAN. Therefore, as users age out, the number of available addresses increases. This leads to a more even
distribution of addresses.
The Even type is only supported in tunnel and decrypt-tunnel modes. It is not supported in split or bridge
modes and it is not allowed for named VLANthat are configured directly under a virtual AP. It can only be used
under named VLANs.
If a named VLANis given an Even assignment and is assigned to user roles, user rules, VSA, or server derivation
rules, then while applying VLAN derivation for the client “on run time,” the Even assignment is ignored and the
Hash assignment is applied with a message displaying this change.
L2 Mobility is not compatible with the existing implementation of the Even named VLANassignment type.
