MAC Locking Tab (Device)

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 left-panel Network Elements tab, and click the MAC Locking tab in the right panel.

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.

Click the graphic for more information.
