Usage guidelines
A MAC address entry includes a destination MAC address, an outgoing interface, and a VLAN ID.
If you do not specify any parameters, the command displays all MAC address entries.
This command displays dynamic MAC address entries for an aggregate interface only when the
aggregate interface has a minimum of one Selected member port.
Multiport unicast MAC address entries have no impact on the MAC address learning. When
receiving a frame whose source MAC address matches a multiport unicast entry, the device can still
learn the MAC address of the frame and generate a dynamic entry. However, the generated dynamic
entry has lower priority. The device prefers to use the multiport unicast entry to forward frames
destined for the MAC address in the entry.
