BRIDGE_PORT
Use the SET VBRIDGE AFT BRIDGE_PORT command to enable source checking
for all MAC addresses of devices attached to a port. Before forwarding any
packet that arrives on the specified port, the SwitchModule checks the address
table to verify that the packet’s source MAC address is valid for the specified
port.
