Configuring AC Roles (New Method)

Configuring AC Roles (New Method)

Context

Traditionally, N+1 backup is configured by specifying IP addresses of the active and standby ACs on each other and configuring AC priorities. The active and standby ACs are then determined based on the priority. To simplify configuration logic, the new configuration method allows you to specify the same primary and backup ACs for APs on the active and standby ACs. The active AC is specified as the primary AC, and the standby AC as the backup AC.

More than two ACs may exist on the N+1 backup network. Each AP has only one active AC and one standby AC planned. You only need to create the same AP system profile on the active and standby ACs, and specify active and standby ACs as the primary and backup ACs respectively in the AP system profile.

You are advised to create different AP system profiles on different active ACs. Otherwise, the standby AC cannot identify AP system profile configurations, causing incorrect configurations.

The following configurations must be performed on both the active and standby ACs.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run wlan

    The WLAN view is displayed.

  3. Run ap-system-profile name profile-name

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

  4. Run primary-access ip-address ip-address

    A primary AC IP address is configured.

    By default, no primary AC IP address is configured.

  5. Run backup-access ip-address ip-address

    A backup AC IP address is configured.

    By default, no backup AC IP address is configured.

  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.

  8. Run quit

    Return to the WLAN view.

  9. Run ap-reset { all | ap-name ap-name | ap-mac ap-mac | ap-id ap-id | ap-group ap-group | ap-type { type type-name | type-id type-id } }

    APs are restarted to make the dual-link backup configurations take effect.

    NOTE:
    • If the dual-link backup function is disabled, running the ac protect enable command restarts online APs. After the APs are restarted, the dual-link backup function takes effect.

    • If the dual-link backup function is enabled, running the ac protect enable command does not restart online APs. You need to run the ap-reset { all | ap-name ap-name | ap-mac ap-mac | ap-id ap-id | ap-group ap-group | ap-type { type type-name | type-id type-id } } command to restart the APs and make the dual-link backup function take effect. You can also manually restart the APs to make the dual-link backup function take effect.

    • If an AP goes online after dual-link backup is configured, you do not need to restart the AP.
