Usage Guidelines

Usage Scenario

In dual-link cold backup scenarios, after an AP becomes Fault on the active AC, switches to the standby AC, and works properly, the active AC generates an AP Fault alarm. If AP Fault alarms are not needed in this case, you can run the ac protect alarm-restrain enable command to enable AP Fault alarm suppression.

After AP Fault alarm suppression is enabled, the active and standby ACs generate AP Fault alarms only when both ACs detect that an AP becomes faulty on them.

Precautions

The active and standby ACs notify each other of the AP status by exchanging packets. If communication between the ACs fails, AP Fault alarm suppression cannot take effect.

AP Fault alarm suppression can only suppress the AP Fault alarms caused by heartbeat timeout. If an AP is deleted or restarted using the undo ap or ap-reset command, the alarms cannot be suppressed.

Example

# Enable AP Fault alarm suppression.
