WLAN Overview
WLAN Overview
The Cisco UWN Solution can control up to 512 WLANs for lightweight access points. Each WLAN has
a separate WLAN ID (1 through 512), a separate profile name, and a WLAN SSID and can be assigned
unique security policies. The controller publishes up to 16 WLANs to each connected access point, but
you can create up to 512 WLANs on the controller and then selectively publish these WLANs (using
access point groups) to different access points to better manage your wireless network.
Cisco 2106, 2112, and 2125 controllers support only up to 16 WLANs.
Note
You can associate up to 16 WLANs with each access point group and assign specific access points to
each group. Each access point advertises only the enabled WLANs that belong to its access point group.
The access point does not advertise disabled WLANs in its access point group or WLANs that belong to
another group. Refer to the
on access point groups.
Controller software releases prior to 5.2 support up to only 16 WLANs. Cisco does not support
Note
downgrading the controller from software release 5.2 to a previous release as inconsistencies might
occur for WLANs and wired guest LANs. As a result, you would need to reconfigure your WLAN,
mobility anchor, and wired LAN configurations.
Cisco recommends that you assign one set of VLANs for WLANs and a different set of VLANs for
Note
management interfaces to ensure that controllers properly route VLAN traffic.
