Usage Guidelines

Usage Scenario

AC1 is the active AC and AC2 is the standby AC. When the link between AC1 and an AP fails, AC2 takes the active role.

When the link between AC1 and the AP recovers, the AP detects that AC1 priority is higher than AC2 and instructs AC1 and AC2 to perform revertive switching. AC1 then becomes the active AC again.

Precautions

  • The undo wlan ac protect restore disable command must be used before an AP goes online and dual-link backup is implemented. In this way, the AC delivers the revertive switching configuration to the AP when the AP goes online.
  • If global revertive switching is disabled, traffic of an AP cannot be switched back to AC1 when the link between AC1 and the AP restores.
  • The command takes effect after an AP restart.

Example

# Disable global revertive switching.
