Configure and Troubleshoot AP Groups

In large WLAN deployments, you might want to reduce the number of users connecting on each VLAN or to control what WLANs are advertised by APs based on the AP location. This is achieved by grouping APs into AP groups.

The AP group configuration allows you to override the default WLAN to a dynamic interface, as well as to select what specific WLANs are enabled on each AP that belongs to the group. The WLAN selection allows you to restrict the WLANs advertised on each AP, but it is crucial when more than 16 WLANs are configured on the WLC.

Although the WLC can handle up to 512 WLANs (except the 2100 Series WLCs that support only up to 16 WLANs), up to 16 can be published to each AP. The default AP group will include the WLANs with IDs 1 to 16, but if you need to advertise an SSID with a higher WLAN ID, you have to configure an AP group and include the needed WLANs.
