Port Participating option to Yes.
Option 3, Port Participating, only applies when the intrusion action is
set to trap or disable. This option does not apply when intrusion action
is set to discard. If this option is set to No when intrusion action is set
to trap or disable, the port discards invalid packets, but it does not
send an SNMP trap or disable the port. If you want the switch to send
a trap and/or disable the port, be sure to sent this option to Yes.
