Lock Address Table(Stop Learning)
Mostly used for security
purposes, when the forwarding table is locked the Switch will no

configuration doesn’t change, locking the forwarding table helps
keep intruders off your network since any packet coming from an
unknown source address will be dropped by the Switch.
