4.7.6.2 Static MAC Address
When you add a static MAC address, it 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.

MAC Address:

forward traffic, regardless of the device network activity.
2.

3.

MAC address.
