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

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:
