Reading Intrusion Alerts and Resetting Alert Flags
Notice of Security Violations
When the switch detects an intrusion on a port, it sets an "alert flag" for that
port and makes the intrusion information available as described below. While
the switch can detect additional intrusions for the same port, it does not list
the next chronological intrusion for that port in the Intrusion Log until the
alert flag for that port has been reset.
When a security violation occurs on a port configured for Port Security, the
switch responds in the following ways to notify you:
I
