Use the drop-down menu to enable or disable the sending of messages to the device's SNMP agent and switch log once the Safeguard Engine has been activated by a high CPU utilization rate. Used to select the type of Safeguard Engine to be activated by the Switch when the CPU utilization reaches a high rate.
