About WLANs in a Cisco Mobility Express Network
You can create and manage Wireless Local Area Networks (WLANs) through the WLAN Configuration window. Choose Wireless Settings > WLANs.
The total number of active WLANs is displayed at the top of the WLAN Configuration window along with a list of all the WLANs currently configured on the primary AP's controller. This list displays the following details for each WLAN:
-
Whether the WLAN is enabled or disabled.
-
Name of the WLAN.
-
Security Policy on WLAN.
-
Radio Policy on WLAN.
Guidelines and Limitations for Setting Up WLANs
-
You can associate up to 16 WLANs with the Cisco Mobility Express controller. Cisco recommends a maximum of 4 WLANs. The controller assigns all the configured WLANs to all the connected APs.
-
Each WLAN has a unique WLAN ID, a unique profile name, and an SSID.
-
The WLAN name and SSID can have up to 32 characters.
-
Each connected AP advertises only the WLANs that are in an Enabled state. The APs do not advertise disabled WLANs.
-
The controller uses different attributes to differentiate between WLANs with the same SSID.
-
Peer-to-peer blocking does not apply to multicast traffic.
-
You cannot map a WLAN to VLAN0, and you cannot map VLANs 1002 to 1006.
-
Dual-stack clients with static IPv4 addresses are not supported.
-
When creating WLANs with the same SSID, create a unique profile name for each WLAN.
-
Starting from Release 8.10.142.0, new SSID and WLAN profile names can have up to four leading spaces. If there are more than four leading spaces in an SSID or WLAN profile name, an error message is displayed. If you upgrade to this release, the existing SSID and WLAN profile names that contain more than four leading spaces are not impacted.
Note
In a Cisco Mobility Express deployment, if you download the Day 0 configuration file through PnP on an AP, leading spaces in SSID names are not checked because of an XML limitation. However, if you convert the AP from another mode to the Mobility Express mode, leading spaces are checked during SSID creation.
