Clearing MAC Address Flapping Records

Clearing MAC Address Flapping Records


  • Cleared MAC address flapping records cannot be restored.
  • When MAC address flapping occurs in a VLAN or BD and the loop is not eliminated, if the interface is added to or removed from an Eth-Trunk, the values of Original-Port and Move-Ports in MAC address flapping records remain unchanged. After the loop is eliminated, delete MAC address flapping entries and perform detection again. This prevents the incorrect source and flapped interfaces from being detected, loop location, and punishment action (Error-Down state or storm control) from being delivered to the incorrect flapped interface.


  • Run the reset mac-address flapping record [ all ] command in the user view to clear MAC address flapping records.
