By default, the inter-VLAN
MAC address replicating
feature is disabled.
z On a port, the inter-VLAN MAC address replicating feature can be configured only once for a
destination VLAN. If the configuration needs to be modified, you need to remove the existing
configuration first.
z With the inter-VLAN MAC address replicating feature disabled, all the MAC address entries that the
destination VLAN learns from the other VLANs through this function are removed.
z MAC address entries obtained through the inter-VLAN MAC address replicating feature cannot be
removed manually. To remove a MAC address entry of this kind, you need to disable the
inter-VLAN MAC address replicating feature first.
z VLAN 4093 is a special VLAN reserved for the IRF fabric feature. It can not serve as the destination
VLAN of the inter-VLAN MAC address replicating feature to receive MAC address entries from the
other VLANs.
