Configuring the Wireless AP

Tunnels can be configured to come up on demand but this is a poor choice for
wireless, since tunnel setup can take roughly 5-20 seconds and present a problem
for authentication.
VLAN Pools
A VLAN pool is a set of VLANs. Using a pool allows a client associating to an AP
to be assigned to one of the VLANs in the pool rather than to a particular VLAN.
This is useful in special networking situations. For example, a large hotel uses
four Internet access gateways to capture Wi-Fi users. Each gateway uses one
VLAN. On the hotel’s APs, we create a VLAN pool with the four gateway
VLANs. When a client connects to an AP, it is assigned to one of the VLANs in the
pool. This distributes users approximately evenly among the gateways, roughly
balancing their loads.
Each client device is assigned to a pool VLAN with a computation based on the
lower digits of its MAC address, so that the device will always be assigned to the
same VLAN. This ensures that a client roaming from one AP to the next will be
handled properly. Note that the VLAN assigned is also based on the VLANs in
the pool, so that if changes are made to the pool, the client device may be assigned
to a different VLAN.
You may specify a VLAN pool rather than a particular VLAN for SSIDs or for
user groups. See
“Procedure for Managing SSIDs” on page 277
.
You may create up to 16 VLAN pools, and each may contain up to the maximum
number of VLANS that may be created on the AP. If a user has a VLAN assigned
via RADIUS authentication, then this VLAN will be used rather than one from the
VLAN pool. If a user has a VLAN assigned via a
, then this VLAN will be
used rather than one from the VLAN pool.
To set up a VLAN pool, see the next section.
