11.3.4 Configuring MAC Locking
Purpose
To review, disable, enable and configure MAC locking. This locks a MAC address to one or more
ports, preventing connection of unauthorized devices via the port(s). When source MAC addresses
are received on specified ports, the switch discards all subsequent frames not containing the
configured source addresses. The only frames forwarded on a “locked” port are those with the
“locked” MAC address(es) for that port.
