Default command level

2: System level

Parameters

blackhole: Specifies destination blackhole MAC address entries. These entries do not age, but you can

add or remove them. The packets whose destination MAC addresses match destination blackhole MAC

address entries are dropped.

mac-address: Specifies a MAC address in the format of H-H-H, where 0s at the beginning of each H

(16-bit hexadecimal digit) can be omitted. For example, entering "f-e2-1" indicates that the MAC address

is "000f-00e2-0001."

vlan vlan-id: Specifies an existing VLAN to which the Ethernet interface belongs. The value range for the

vlan-id argument is 1 to 4094.

dynamic: Specifies dynamic MAC address entries, which can be aged.

static: Specifies static MAC address entries. These entries do not age, but you can add or remove them.

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

Usage guidelines

A static or blackhole MAC address entry will not be overwritten by a dynamic MAC address entry. A

dynamic MAC address entry can be overwritten by a static or blackhole MAC address entry.

If you execute the undo mac-address command without specifying any parameters, this command

deletes all unicast MAC address entries and static multicast MAC address entries.

You can delete all the MAC address entries (including unicast MAC address entries and static multicast

MAC address entries) of a VLAN, or you can choose to delete a specific type (dynamic, static, or

blackhole) of MAC address entries only. You can single out certain ports and delete the corresponding

unicast MAC address entries, but you cannot do the same to the corresponding static multicast MAC

address entries.

The MAC address entries configuration cannot survive a reboot unless you save it. However, the dynamic

MAC address table entries are lost at next reboot regardless of whether you save the configuration or not.

Examples

# Add a static entry for MAC address 000f-e201-0101. All frames destined to this MAC address are sent

out of GigabitEthernet 4/0/1 that belongs to VLAN 2.
