Setting the Primary or Secondary Wireless Controllers for Availability

1. From the top menu, click Controller. The Wireless Controller Configuration screen displays.
2. In the left pane, click Administration > Availability.
   

   
3. To enable availability, select the Paired option.
4. Do one of the following:
   • For a primary controller, in the Wireless IP Address box, type the IP address of the data interface of the secondary controller. This IP address must be on a routable subnet between the two controllers.
   • For a secondary controller, in the Wireless IP Address box, type the IP address of the Management port or data interface of the primary controller.
5. Set this controller as the primary or secondary connection point:
   • To set this controller as the primary connection point, select the Current Wireless is primary connect point checkbox.
   • To set this controller as the secondary connection point, clear the Current Wireless is primary connect point checkbox.

     If the Current Wireless is primary connect point checkbox is selected, the specified controller sends a connection request. If the Current Wireless is primary connect point checkbox is cleared, the specified controller waits for a connection request. Confirm that one controller has this checkbox selected, and the second controller has this checkbox cleared, since improper configuration of this option will result in incorrect network configuration.

6. On both the primary and secondary controllers, type the Detect link failure value.
   

   Note

   Ensure that the Detect link failure value on both the controllers is identical.
7. On both the primary and secondary controllers, select the Synchronize GuestPortal Guest Users option to synchronize GuestPortal guest accounts between the controllers.
8. From the top menu, click AP.
9. In the left pane, click Global Settings > AP Registration. To set the security mode for the controller, select one of the following options:
   • Allow all wireless APs to connect — If the controller does not recognize the serial number, it sends a default configuration to the AP. Or, if the controller recognizes the serial number, it sends the specific configuration (port and binding key) set for that AP.
   • Allow only approved wireless APs to connect — If the controller does not recognize the serial number, the APs will be in pending mode and the administrator must manually approve them. Or, if the controller recognizes the serial number, it sends the configuration for that AP.
   

   Note

   During the initial setup of the network, it is recommended that you select the Allow all Wireless APs to connect option. This option is the most efficient way to get a large number of APs registered with the controller. Once the initial setup is complete, it is recommended that you reset the security mode to the Allow only approved Wireless APs to connect option. This option ensures that no unapproved APs are allowed to connect. For more information, see Configuring Wireless AP Properties.
10. To save your changes, click Save.
    

    Note

    When two controllers have been paired as described above, each controller's registered APs will appear as foreign on the other controller in the list of available APs when configuring a VNS topology.
11. Verify that availability is configured correctly.
