Master Cisco Wireless LAN Controller

When you are adding Cisco 1000 Series lightweight access points to a 

 network, it is convenient to have all Cisco 1000 Series lightweight access points 

associate with one Master Cisco Wireless LAN Controller on the same subnet. That way, the operator 
does not have to log into multiple Cisco Wireless LAN Controllers to find out which Cisco Wireless LAN 
Controller newly-added Cisco 1000 Series lightweight access points associated with.
One Cisco Wireless LAN Controller in each subnet can be assigned as the Master Cisco Wireless LAN 
Controller while adding Cisco 1000 Series lightweight access points. As long as a Master Cisco Wireless 
LAN Controller is active on the same subnet, all new Cisco 1000 Series lightweight access points 
without a 

 assigned automatically 

attempt to associate with the Master Cisco Wireless LAN Controller. This process is described in 

.

The operator can monitor the Master Cisco Wireless LAN Controller using the 

 or the 

 GUI, and watch as Cisco 1000 Series lightweight access points associate 

with the Master Cisco Wireless LAN Controller. The operator can then verify Cisco 1000 Series light-
weight access point configuration and assign a 

 to the Cisco 1000 Series lightweight access point, and reboot the Cisco 1000 Series light-

weight access point so it reassociates with its Primary, Secondary, or Tertiary Cisco Wireless LAN 
Controller.

Primary, Secondary, and Tertiary Cisco 

Wireless LAN Controller

 networks, Cisco 1000 Series lightweight access 

points can associate with any Cisco Wireless LAN Controller on the same subnet. To ensure that each 
Cisco 1000 Series lightweight access point associates with a particular Cisco Wireless LAN Controller, 
the operator can assign Primary, Secondary, and Tertiary Cisco Wireless LAN Controllers to the Cisco 
1000 Series lightweight access point.
When a Cisco 1000 Series lightweight access point is added to a network, it looks for its Primary, 
Secondary, and Tertiary Cisco Wireless LAN Controllers first, then a 

, then the least-loaded Cisco Wireless LAN Controller with available Cisco 1000 Series light-

weight access point ports. Refer to 

information.

 Cisco 1000 Series lightweight access points without a 

 assigned always search for a Master Cisco 

Wireless LAN Controller first upon reboot. After adding Cisco 1000 Series lightweight 
access points through the Master Cisco Wireless LAN Controller, assign Primary, 
Secondary, and Tertiary Cisco Wireless LAN Controllers to each Cisco 1000 Series 
lightweight access point. 
Cisco WLAN Solution recommends that you disable the Master setting on all Cisco 
Wireless LAN Controllers after initial configuration. 
Because the Master Cisco Wireless LAN Controller is normally not used in a deployed 
network, the Master Cisco Wireless LAN Controller setting is automatically disabled 
upon reboot or OS code upgrade.
