(4402-a) >config network ap-priority enable Then specify the priority of an AP by entering this CLI command. You can use CLI to configure this as well.Ĭonfig advanced backup-controller primary Ĭonfig advanced backup-controller secondary Ĭonfig advanced timers ap-fast-heartbeat ” command. You can configure this through “Wireless -> All AP -> Global Configuration” section as shown in the below.You enable/disable Fast Heartbeat for local/H-REAP from the same page. Should you want to set a global primary backup and or secondary backup controller for all the APs joined to a particular controller. Here is an example of where I have configured primary,secondary, tertiary controller information for an AP named “1252-c” (4402-a) >config ap primary-base 4402-a 1252-c 10.10.20.100 You can configure the same via WLC CLI using following 3 commands.Ĭonfig ap primary-base Ĭonfig ap secondary-base Ĭonfig ap tertiary-base You can configure your wireless network so that the backup controller recognize a join request from a higher priority AP and if necessary disassociates a lower priority AP as a means to provide an available port for higher fail over priority AP.īelow show the Primary, Secondary, Tertiary controller settings for a AP.(In High Availabilty tab of AP configuration) If the AP is not able to join any of the configured controllers, it try to join any controller with Master Controller setting configured, or if no Master Controller, then the least loaded controller in the Mobility Group.ĪP Failover priority can be used to determine who will register for a controller if there is a contention. Should the primary controller go down, the AP tries to register with the secondary controller. With the controller name configured on APs, the APs always try to register the primary controller first. If you want to have more control over how the APs move between controllers on your network, you can configure the APs with Primary, Secondary & Tertiary controller names. Once fully configured, Appriority works by suspending and resuming applications as you switch among them. If many controllers in the mobility group, it can be difficult to determine what controller the APs will join should their current controller fail. Appriority is an easy-to-use tool for OS X that simply makes the app you're working in go faster by allowing you to optimize the CPU load on your computer. Assuming one of the controller has the capacity to accept the AP, the AP should join the least loaded controller it can find. Stampboards had many members mail a bunch of letters with 1 stamps, and just as many with 1.50 to same address, and in the main the delivery time was the same. Should the controllers that an AP is currently registered with go down, the AP will send discoveries to any and all controllers in the mobility group. When an AP is fully joined to a controller, the AP learns of all the controllers configured in that mobility group.
