Intruder on Port A1
Earlier intrusions on port
A1 that have already been
cleared (that is, the Alert
Flag has been reset at
least twice before the
most recent intrusion
occurred.
In the following example, executing show interfaces brief lists the switch's port
status, which indicates an intrusion alert on port A1.

If you wanted to see the details of the intrusion, you would then enter the show
port-security intrusion-log command. For example:

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.
To clear the intrusion from port A1 and enable the switch to enter any
subsequent intrusion for port A1 in the Intrusion Log, execute the port-security
clear-intrusion-flag command. If you then re-display the port status screen, you
