mac

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

address is "000f-00e2-0001".

vlan-id
is the
specified VLAN ID, ranging from 1 to 4094.

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

Description
Use
mac-address
to add or modify a MAC address entry.
Use
undo mac-address
to remove one or all MAC address entries.
A static MAC address entry can overwrite a dynamic MAC address entry, but not vice versa.
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 or static) of MAC address entries only. You can single out certain ports and delete the
corresponding unicast MAC address entries.
The static MAC address entries configuration cannot survive a reboot unless you save it. The dynamic
MAC address table entries, however, are lost at reboot whether or not you save the configuration.
