Verifying Session Availability

To have session availability, you must ensure the following:

  • The primary and secondary wireless controllers are properly configured in ‘availability‘ mode. For more information, see Availability.
  • The fast failover feature is properly configured. For more information, see Configuring Fast Failover and Enabling Session Availability.
    Note

    Note

    If you haven‘t configured the fast failover feature, the Enable Session Availability checkbox is not displayed.
  • Time on all the network elements — both the wireless controllers in availability pair, APs, DHCP (Dynamic Host Configuration Protocol) and RADIUS servers etc.— is synchronized. For more information, see Configuring Network Time.
  • Both the wireless controllers in fast failover mode must be running the most recent wireless controller software release.
  • If you are using Bridge Traffic Locally at Controller topology, you must select None from the DHCP Option drop-down menu.
  • The Bridge Traffic Locally at Controller must be mapped to the same VLAN on both the primary and secondary wireless controllers.

    To Verify the Session Availability Feature Is Configured Correctly:

  3. Check the statement at the top of the screen.

    If the statement reads Availability link is up, the availability feature is configured correctly. If the statement reads Availability link is down, check the configuration error in logs. For more information on logs, see the Extreme Networks ExtremeWireless Maintenance Guide.
