6.26 MAC Address Table
Use the MAC address table to ensure the port security.
6.26.1 Static MAC Address
You can add a static MAC address that remains in the switch's address table regardless
of whether the device is physically connected to the switch. This saves the switch from
having to re-learn a device's MAC address when the disconnected or powered-off device
is active on the network again. Via this interface, you can add / modify / delete a static
MAC address.
