Address Table Commands 309
User Guidelines
When port security is enabled on an interface, all dynamic entries learned up
to that point are flushed, and new entries can be learned only to the limit set
by the port security max command. The default limit is 100 dynamic MAC
addresses.
Example
In this example, frame forwarding is enabled without learning, and with traps
sent every 100 seconds on port gi1/0/1.
console(config)#interface gigabitethernet te1/0/1
console(config-if-Te1/0/1)#port security trap 100
port security max
Use the port security max command in Interface Configuration mode to
