User's Manual

The Even VLAN pool assignment type is only supported in tunnel and dtunnel modes. It is not supported in split or
bridge modes. It is not allowed for VLAN pools 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 VLAN pool
assignment type.

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 VLAN pool assignments.
The Even VLAN Pool assignment type maintains a dynamic latest usage level of each VLAN ID in the pool.
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 dtunnel modes. It is not supported in split or bridge modes and
it is not allowed for VLAN pools that are configured directly under a virtual AP. It can only be used under
named VLANs.
