Port Security Commands
This section describes the command used to configure Port Security on the switch. Port security, which
is also known as port MAC locking, allows you to secure the network by locking allowable MAC
addresses on a given port. Packets with a matching source MAC address are forwarded normally, and all
other packets are discarded.

To enable the SNMP (Simple Network Management Protocol) trap specific to port security,
see snmp-server enable traps violation on page 93.
