Any view 

mac-address: Displays MAC address entries in a specified MAC address, in the format of H-H-H. 

static: Displays static MAC address entries. Similar to blackhole MAC address entries, these entries do 

not age but you can add or remove them. 

dynamic: Displays dynamic MAC address entries. Aging time is set for these entries. 

blackhole: Displays blackhole MAC address entries. These entries do not age but you can add or 

remove them. Packets whose destination MAC addresses or source MAC addresses match destination 

blackhole MAC address entries are dropped. 

interface-type interface-number: Displays MAC address learning status of the specified interface. 

interface-type interface-number specifies an interface by its type and number. 

vlan-id: Displays MAC address entries of the specified VLAN, where vlan-id is in the range 1 to 4094. 

count: Displays the number of MAC address entries specified by related parameters in the command. 

When this keyword is used, the command displays only the number of specified MAC address entries, 

rather than related information about these MAC address entries. 

statistics: Displays statistics of the MAC address entries maintained by the switch. 

unit unit-id: Displays information about the MAC address forwarding table of the specified unit in the 

fabric. 

Use the display mac-address command to display information about MAC address entries in the MAC 

address table, including: MAC address, VLAN and port corresponding to the MAC address, the type 

(static or dynamic) of a MAC address entry, whether a MAC address is within the aging time and so on. 

If you specify a unit ID with unit unit-id, the information about the MAC address entries on the specified 

device in the fabric will be displayed.
