Parameters

mac-address: Specifies a MAC address in the format of H-H-H. When entering a MAC address, you can

omit the leading zeros in each H section. For example, enter f-e2-1 for 000f-00e2-0001.

vlan vlan-id: Specifies a VLAN by its ID in the range of 1 to 4094.

dynamic: Displays dynamic MAC address entries.

static: Displays static MAC address entries.

interface interface-type interface-number: Specifies an interface by its type and number.

blackhole: Displays blackhole MAC address entries.

count: Displays the total number of MAC address entries that match all entry attributes you specify in the

command. For example, you can use the display mac-address vlan 20 dynamic count command to

display the total number of dynamic entries for VLAN 20. If you do not specify an entry attribute, the

command displays the total number of entries in the MAC address table. If you do not specify this

keyword, the command displays detailed information about the specified MAC address entries.

Usage guidelines

A MAC address entry includes a destination MAC address, an outgoing interface, and a VLAN ID.

If you execute this command without specifying any parameters, it displays all MAC address entries.

Examples

# Display MAC address entries for VLAN 100.

<Sysname> display mac-address vlan 100
