Configuring an
Auto-AP Profile for
Automatic MAP
Configuration
You can use an Auto-AP profile to deploy unconfigured Distributed
MAPs. A Distributed MAP that does not have a configuration on a WX
switch can receive its configuration from the Auto-AP profile instead.
The Auto-AP profile assigns a Distributed MAP number and name to the
MAP, from among the unused valid MAP numbers available on the
switch. The Auto-AP profile also configures the MAP with the MAP and
radio parameter settings in the profile. The MAP and radio parameter
settings in the Auto-AP profile are configurable. (See “Configuring an
Auto-AP Profile” on page 220.)
The Auto-AP profile does not control SSIDs, encryption parameters, or
any other parameters managed by service profiles. You still need to
configure a service profile separately for each SSID.
A WX switch can have one Auto-AP profile.
How an Unconfigured MAP Finds a WX To Configure It
The boot process for a Distributed MAP that does not have a
configuration on a WX switch is similar to the process for configured
Distributed MAPs. After the MAP starts up, it uses DHCP to configure its
IP connection with the network. The MAP then uses the IP connection to
contact a WX switch.
The WX switch contacted by the MAP determines the best switch to use
for configuring the MAP, and sends the MAP the IP address of that
switch. The best switch to use for configuring the MAP is the switch that
has an Auto-AP profile with a high bias setting. If more than one WX has
an Auto-AP profile with a high bias setting, the switch that has the
greatest capacity to add new unconfigured MAPs is selected.
A WX with the capacity to add new unconfigured Distributed MAP is the
lesser of the following:
„
Maximum number of MAPs that can be configured on the WX, minus
the number that are configured
„
Maximum number of MAPs that can be active on the WX, minus the
number that are active
