The mac-address flapping detection exclude vlan command excludes a VLAN from MAC address flapping detection.
The undo mac-address flapping detection exclude vlan command restores MAC address flapping detection for a VLAN.
By default, the system performs MAC address flapping detection in all VLANs.
mac-address flapping detection exclude vlan { vlan-id1 [ to vlan-id2 ] } &<1-10>
undo mac-address flapping detection exclude vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }

vlan-id1 [ to vlan-id2 ] |
Specifies the ID of a VLAN where MAC address flapping detection is not required.
vlan-id2 must be greater than vlan-id1. You can specify a maximum of 10 VLANs. |
|
|
all |
Indicates that all VLANs are excluded from MAC address flapping detection. |

Usage Scenario
By default, the system performs MAC address flapping detection in all VLANs. When a switch connected to a load balancing server with dual network adapters, the server's MAC address may be learned by two interfaces on the switch. This is a normal situation where MAC address flapping detection is not required.
You can run the mac-address flapping detection exclude vlan command to exclude a VLAN from MAC address flapping detection. If MAC address flapping occurs in this VLAN, the system does not send a trap message or record this event.
Precautions
If you run the mac-address flapping detection exclude vlan command multiple times, multiple VLANs are excluded from MAC address flapping detection.
