MAC address table configuration commands
The MAC address table can contain only Layer 2 Ethernet ports and Layer 2 aggregate interfaces.
This document covers only the configuration of unicast MAC address table entries, including static,
dynamic, and blackhole MAC address table entries.
display mac-address
Description
Use the display mac-address command to display information about the MAC address table.
If you execute this command without specifying any parameters, it displays information of all MAC
address entries on the device, including unicast MAC address entries and static multicast MAC address
entries.
If you execute this command using only the vlan parameter or the count parameter, or only these two
parameters, it displays information of unicast MAC address entries and static multicast MAC address
entries.
Related commands: mac-address (system view), mac-address (interface view), and mac-address timer.
