Command Usage
The static address for a host device can be assigned to a specific port within
a specific VLAN. Use this command to add static addresses to the MAC
Address Table. Static addresses have the following characteristics:
• Static addresses will not be removed from the address table when a given
interface link is down.
• Static addresses are bound to the assigned interface and will not be moved.
When a static address is seen on another interface, the address will be
ignored and will not be written to the address table.
• A static address cannot be learned on another port until the address is
removed with the no form of this command.
Example
clear mac-address-table dynamic
This command removes any learned entries from the forwarding database and
clears the transmit and receive counts for any static or system configured entries.
Default Setting
None
Command Mode
Privileged Exec
