that are enabled for port security. The following table describes the fields in the Port Security
Violation table.
Field Description
Port Identifies the port where a violation occurred.
Last Violation MAC Displays the source MAC address of the last
packet that was discarded at a
locked port.
VLAN ID Displays the VLAN ID corresponding to the Last Violation MAC address.

Port Security Interface Configuration
A MAC address can be defined as allowable by one of two methods: dynamically or statically.
Both methods are used concurrently when a port is locked.
Dynamic locking implements a first arrival mechanism for Port Securit
y. You specify how
many addresses can be learned on the locked port. If the limit has not been reached, then a
packet with an unknown source MAC address is learned and forwarded normally. When the
limit is reached, no more addresses are learned on the port. Any packets with source MAC
addresses that were not already learned are discarded. You can effectively disable dynamic
locking by setting the number of allowable dynamic entries to zero.
Static locking allows you to specify a list of
MAC addresses that are allowed on a port. The
behavior of packets is the same as for dynamic locking: only packets with an allowable
source MAC address can be forwarded.
