Rising Threshold (20%

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.
Mode
Used to select the type of Safeguard Engine to be activated by the Switch when the
CPU utilization reaches a high rate. The user may select:
Fuzzy
– If selected, this function will instruct the Switch to minimize the IP and ARP
traffic flow to the CPU by dynamically allotting an even bandwidth to all traffic flows.
Strict
– If selected, this function will stop accepting all ARP packets not intended for
the Switch, and will stop receiving all unnecessary broadcast IP packets, until the
storm has subsided.
The default setting is
Fuzzy
mode.
