A WLAN is a data-communications system that flexibly extends the functionality of a wired LAN. A WLAN links two or more computers or devices using spread-spectrum or OFDM (Orthogonal Frequency Division Multiplexing) modulation based technology. WLANs do not require lining up devices for line-of-sight transmission, and are thus, desirable for wireless networking. Roaming users can be handed off from one access point to another, like a cellular phone system. WLANs can therefore be configured around the needs of specific user groups, even when they are not in physical proximity.
WLANs can provide an abundance of services, including data communications (allowing mobile devices to access applications), e-mail, file, and print services or even specialty applications (such as guest access control and asset tracking).
Each WLAN configuration contains encryption, authentication and QoS policies and conditions for user connections. Connected access point radios transmit periodic beacons for each BSS. A beacon advertises the SSID, security requirements, supported data rates of the wireless network to enable clients to locate and connect to the WLAN.
WLANs are mapped to radios on each access point. A WLAN can be advertised from a single access point radio or can span multiple access points and radios. WLAN configurations can be defined to provide service to specific areas of a site. For example, a guest access WLAN may only be mapped to a 2.4 GHz radio in a lobby or conference room providing limited coverage, while a data WLAN is mapped to all 2.4 GHz and 5.0 GHz radios at the branch site to provide complete coverage.
wlan {<WLAN-NAME>|containing <WLAN-NAME>}
wlan {<WLAN-NAME>|containing <WLAN-NAME>}
| wlan <WLAN-NAME> | Configures a new WLAN
Note: The WLAN name
could be a logical representation of its coverage area (for example,
engineering, marketing etc.). The name cannot exceed 32
characters.

The following example shows how to use the ‘containing‘ keyword to enter the configuration mode of an existing WLAN:
nx9500-6C8809(config)#wlan containing wlan1 nx9500-6C8809(config-wlan-{'containing': 'wlan1'})#
| no | Removes an existing WLAN from the system |
