- If so, go to Step 2.
- If not, go to Step 4.
- Run the traffic-optimize broadcast-suppression enable command in the system profile to enable the rate limit for broadcast packets and IGMP multicast packets on the AP. Check whether the alarm persists.
- If so, go to Step 3.
- If not, go to Step 4.
- Collect alarm, log, and configuration information, and contact technical support personnel.
- End.
