What Should I Do When Finding a MAC Address Flapping Alarm on Huawei S5700 Switch?

If MAC Address Flapping Alarm is reported only once on your Huawei S5700 Switch, ignore it.

If the alarm is reported multiple times, find the first and second interfaces where the MAC Address is learned. Shut down the second interface on Switch like S5720-36C-EI-28S-AC to locate the loop. Then adjust the networking to remove the loop.
