Chapter 6 Configuring WLANsWireless Device Access
WLAN Overview
WLAN Overview
The Cisco UWN Solution can control up to 16 WLANs for lightweight access points. Each WLAN has
a separate WLAN ID (1 through 16), a separate WLAN SSID (WLAN name), and can be assigned unique
security policies.
Lightweight access points broadcast all active Cisco UWN Solution WLAN SSIDs and enforce the
policies that you define for each WLAN.
Note Cisco recommends that you assign one set of VLANs for WLANs and a different set of VLANs for
management interfaces to ensure that controllers properly route VLAN traffic.

Displaying, Creating, Disabling, and Deleting WLANs
On the controller CLI, enter these commands to display, create, disable, and delete WLANs:
• Enter show wlan summary to display existing WLANs and whether they are enabled or disabled.
Note that each WLAN is assigned a WLAN ID from 1 to 16.
• Enter config wlan create wlan-id wlan-name to create a new WLAN. For wlan-id, enter an ID from
1 to 16. For wlan-name, enter an SSID of up to 31 alphanumeric characters.
