FortiWLC – VLAN Pooling

VLAN Pooling

To reduce big broadcast or risking a chance of running out of address space, you can now enable VLAN pooling in an ESS profile.

VLAN pooling essentially allows administrators to create a named alias using a subset of VLANs thereby creating a pool of address. By enabling VLAN pool, you can now associate a client/device to a specific VLAN. This allows you to effectively manage your network by monitoring appropriate or specific VLANs pools.

  • You can associate up to 16 VLANs to a pool.
  • You can create a maximum of 64 VLAN Pools.
  • You can specify the maximum number of clients that can be associated to a VLAN.
  • The client/device behaviour does not change after it is associates to a VLAN in a pool. If a VLAN is removed from a VLAN pool, clients/devices connected to the VLAN will continue to be associated to the VLAN. However, if the clients disconnect and reconnect the VLAN will change.
