Mac-hopping exist.(VlanId=[VlanId], Vsi=[vsi_name], BDId=[BD_ID], the port list of Mac-hopping = [PortName1], [PortName2], [PortName3], [PortName4], the peer list of Mac-hopping = [PeerList], DetectMac = [DetectMac], trustport = [TrustPortName], trustpeer = [TrustPeerInfo])
MAC flapping-based loop detection is enabled by default. An alarm is generated when MAC flapping reaches the configured alarm threshold.
In VS mode, this trap is supported only by the admin VS.

1.After a Layer 2 loop appears, broadcast storm occurs on this loop. A large number of broadcast packets are continuously sent to the CPUs of Layer 3 devices on the Layer 2 loop. As a result, the control planes of boards on Layer 3 devices are overloaded and fail to process protocol packets properly.
2.After MAC flapping is enabled, some interfaces will be blocked.
1.Check that the source interface corresponding to the transited MAC address is correctly configured.
2.Check that the source interface corresponding to the transited MAC address is correctly connected.
3.Enable MAC flapping to block the corresponding source interface.
4.Collect alarm information, log information and configuration information, and then contact technical support personnel.
