Configuring and Monitoring Port Security
Reading Intrusion Alerts and Resetting Alert Flags
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
will see that the Intrusion Alert entry for port A1 has changed to “No”.
(Executing show port-security intrusion-log again will result in the same display
as above, and does not include the Intrusion Alert status.)
ProCurve(config)# port-security a1 clear-intrusion-flag
ProCurve(config)# show interfaces brief
Intrusion Alert on port A1 is now

page 13-35
Using the Event Log To Find Intrusion Alerts
The Event Log lists port security intrusions as:
W MM/DD/YY HH:MM:SS FFI: port A3 — Security Violation
where “
W” is the severity level of the log entry and FFI is the system module
that generated the entry. For further information, display the Intrusion Log,
as shown below.
From the CLI. Type the log command from the Manager or Configuration
level.
Syntax: log < search-text >
For < search-text >, you can use ffi, security, or violation. For example:
13-39
