5. In the Primary Gateway Address field, enter the IP address or fully-qualified domain name (FQDN) of the primary gateway server.
6. In the Secondary Gateway Address field, enter the IP address or fully-qualified domain name (FQDN) of the secondary gateway server.
   NOTE

   If the controller is unable to reach the primary gateway server, the controller automatically attempts to reach the secondary gateway address at the IP address specified by you.
7. For Gateway Path MTU, set the maximum transmission unit (MTU) for the gateway path.
   Select one of the following options:

   • Auto: This is the default option.
   • Manual: The transmission range is from 850 through 1500 bytes.
8. In the ICMP Keep Alive Period field, enter the time interval in seconds.
   NOTE

   Time interval is the time taken by the APs to send a keepalive message to an active third party WLAN gateway. The range is from 1 through 180 seconds. The default value is 10 seconds.
9. In the ICMP Keep Alive Retry field, enter the number of keepalive attempts.
   NOTE

   Keepalive attempts are the number of attempts that the APs wait for a response from the active third party WLAN gateway before failing over to the standby WLAN gateway. The range is from 2 through 10 attempts. The default value is 5 attempts.
10. Under Force Disassociate Client, enable Disassociate client when AP fails over to another tunnel if you want to disassociate the client when AP fails over to another tunnel.
    NOTE

    You must select this option if you have enabled AAA Affinity while configuring the zone.
