Participating
This column applies only when the intrusion action on a port is set
to trap or disable. It does not apply when intrusion action is set to
discard. If this column contains No when intrusion action is set to
trap or disable, the port discards invalid packets, but it does not
send the SNMP trap or disable the port. When this column
contains Yes, the port sends a trap and/or is disabled after
receiving an invalid frame.
MAC Limit
This column specifies the maximum number of dynamic MAC
addresses the port will learn. It only applies when a port is
operating in the Limited security mode.
