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.
You can delete all the 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.
