Configuring AC Roles (Traditional Method 1)

Configuring AC Roles (Traditional Method 1)

Context

N+1 backup uses one standby AC to back up multiple active ACs. An AP determines AC roles based on AC priorities. It selects the AC with a higher priority as the active AC and the AC with a lower priority as the standby AC. The AP sets up a connection with the AC of the specified IP address.

An AP can discover only two ACs. Therefore, you only need to configure a global priority for each AC, so that the AP can determine the active and standby ACs by comparing their global priorities.

Procedure

  • Configure the active AC.

    Perform the following configurations on the active AC:

    1. Run system-view

      The system view is displayed.

    2. Run wlan

      The WLAN view is displayed.

    3. Run ac protect protect-ac ip-address

      The standby AC's IP address is configured in the WLAN view.

      By default, no standby AC IP address is configured in the WLAN view.

    4. Run ac protect priority priority

      The global priority of the active AC is configured in the WLAN view.

      By default, the AC priority in the WLAN view is 0.

      NOTE:

      The global priority of the standby AC must be lower than that of the active AC.

      A smaller priority value indicates a higher priority.

  • Configure the standby AC.

    Perform the following configurations on the standby AC:

    1. Run system-view

      The system view is displayed.

    2. Run wlan

      The WLAN view is displayed.

    3. Run ac protect priority priority

      The global priority of the standby AC is configured.

      By default, the AC priority in the WLAN view is 0.

      NOTE:

      The global priority of the standby AC must be lower than that of the active AC.

      A smaller priority value indicates a higher priority.

    4. Run ap-system-profile name profile-name

      An AP system profile is created and the AP system profile view is displayed.

      By default, the system provides the AP system profile default.

    5. Run protect-ac ip-address ip-address

      The active AC's IP address is configured in the AP system profile view.

      By default, no standby AC's IP address is configured in the AP system profile view.

      If multiple APs have the same active AC, configure the active AC's IP address for the APs on the standby AC in the AP system profile, and bind the AP system profile to an AP group.

    6. Run quit

      Return to the WLAN view.

    7. The AP system profile is bound to an AP group.

      • Binding an AP system profile to an AP group.
        1. Run the ap-group name group-name command to enter the AP group view.
        2. Run the ap-system-profile profile-name command to bind the AP system profile to the AP group.

          By default, the AP system profile default is bound to an AP group.

      • Binding an AP system profile to an AP.
        1. Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
        2. Run the ap-system-profile profile-name command to bind the AP system profile to the AP.

          By default, no AP system profile is bound to an AP.
