Configuring and Monitoring Port Security

Reading Intrusion Alerts and Resetting Alert Flags

In the following example, executing show interfaces brief lists the switch’s port

status, which indicates an intrusion alert on port A1.

Figure 14-16.Example of an Unacknowledged Intrusion Alert in a Port Status Display

If you wanted to see the details of the intrusion, you would then enter the show

port-security intrusion-log command. For example:

Figure 14-17.Example of the Intrusion Log with Multiple Entries for the Same Port

The above example shows three intrusions for port A1. Since the switch can

show only one uncleared intrusion per port, the older two intrusions in this

example have already been cleared by earlier use of the clear intrusion-log or

the port-security < port-list > clear-intrusion-flag command. (The intrusion log

holds up to 20 intrusion records, and deletes intrusion records only when the

log becomes full and new intrusions are subsequently added.) The “prior to”

text in the record for the third intrusion means that a switch reset occurred

at the indicated time and that the intrusion occurred prior to the reset.

clear intrusion-flags

Clear intrusion flags on all ports.

port-security [e] < port-number > clear-intrusion-flag

Clear the intrusion flag on one or more specific ports.
