After 100 security violations occur, the device disables learning on the interface and drops all ingress traffic
from nonsecure MAC addresses. In addition, the device generates an SNMP trap for each security violation.
•
Protect
—
Prevents further violations from occurring. The address that triggered the security violation is
learned but any traffic from the address is dropped. Further address learning stops.
If a violation occurs because ingress traffic from a secure MAC address arrives at a different interface than
the interface on which the address is secure, the device applies the action on the interface that received the
traffic.
This command does not require a license.
Examples This example shows how to configure an interface to respond to a security violation event with the protect
action:
switch# configure terminal
switch(config)# interface ethernet 2/1
switch(config-if)# switchport port-security violation protect
switch(config-if)#
