vlan-id
is the
specified VLAN ID, in the range 1 to 4094.

number

Description
Use the
mac-address
command to add or modify a MAC address entry.
Use the
undo mac-address
command to remove one or all MAC address entries.
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 its dynamic, static, or blackhole MAC
address entries only. You can single out some ports and delete the corresponding unicast MAC address
entries, but not the corresponding static multicast MAC address entries.
The MAC address entries configuration cannot survive a reboot unless you save it. The dynamic MAC
address table entries will be lost, whether you save the configuration or not.
