Cause 4: The AS restarted.

Run the display as { all | name as-name | mac-address mac-address | vpn-instance information } command to check whether the AS is online.
- If so, the alarm handling ends.
- If not, go to step 2.
Check whether the AS is manually forced offline.
- If so, the alarm handling ends.
- If not, go to step 3.
Check whether the AS is powered off or restarted.
- If so, find out the cause.
  - Check whether the AS voltage is unstable. If so, add voltage regulators or adjust power supply.
  - If the AS connects to the parent across a network, the AS may restart because of attacks. To check whether attacks occur, log in to the AS and run the display as access configuration command. If the Current connected access controller field displays a different IP address than the currently used parent IP address, an attack from third-party devices occurs. To defend this attack, configure the DHCP snooping function on the intermediate device.
- If not, go to step 4.
Check whether the link between the AS and parent fails, for example, check whether the link is Down. If the link between the AS and parent is normal while the trap still exists.
- If so, collect alarm information and configuration information, and then contact technical support personnel.
- If not, the alarm handling ends.
