Query MAC address flapping records on S series switch

When loops occur on S series switches (except S1700), MAC address flapping often occurs. You can check whether MAC address flapping occurs on a switch to determine whether a loop occurs on the switch. Methods to check MAC address flapping vary depending on the system version.
1. In versions earlier than V200R001 on S series switches:
Run the display trapbuffer command. If the command output displays MAC move detected, MAC address flapping occurred on the switch.
2. E series switches and S series switches running V200R001 and later versions:
- Run the display trapbuffer command. If the command output displays MAC move detected, MAC address flapping occurred on the switch.
- Run the display mac-address flapping record command. If information is displayed, MAC address flapping occurred on the switch.
