The device MAC Locking tab lets you enable the MAC Locking feature on devices that support it. You can
also view and change a list of MAC addresses that are currently locked on the selected
device. (Click the Retrieve button to display this information.) To access this tab, select
a device that supports MAC Locking on the

MAC
Locking ensures that only a specific MAC address can access a port, and that
traffic from any other MAC addresses will be discarded. In order for MAC Locking
to take effect on a port, it must first be enabled at the device level. You can
do this on this tab, or in the
Device Configuration wizard.
