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 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.
Brocade Mobility RFS4000 and Brocade Mobility RFS6000 controllers support a maximum of 32
WLANs. The Brocade Mobility RFS7000 model wireless controller supports up to 256 WLANs. An
access point supports a maximum of 16 WLANs.

Example
rfs7000-37FABE(config)#wlan 1
rfs7000-37FABE(config-wlan-1)#
rfs7000-37FABE(config)#wlan containing wlan1

wlan
<WLAN-NAME> Configures a new WLAN
•
<WLAN-NAME> – Optional. Specify the WLAN name.
The WLAN name could be a logical representation of its coverage area (for example, engineering, marketing
etc.).The name cannot exceed 32 characters.
containing
<WLAN-NAME> Optional. Configures an existing WLAN’s settings
•
<WLAN-NAME> – Specify a sub-string in the WLAN name. Use this parameter to filter a WLAN. This
option allows you to select and enter the configuration mode of one or more WLANs.
