Used to configure the Safeguard Engine settings for the Switch.
config safeguard_engine {state [enable | disable] | utilization {rising
<value 20-100> | falling <value 20-100> | trap_log [enable | disable} |
mode [strict | fuzzy]}
This command is used to configure the settings for the Safeguard
Engine function of this Switch, based on CPU utilization.
state [enable | disable] – Select the running state of the Safeguard
Engine function as enable or disable.
utilization – Select this option to trigger the Safeguard Engine function to
enable based on the following determinates:

rising <value 20-100> - The user can set a percentage value of the
rising CPU utilization which will trigger the Safeguard Engine
function. Once the CPU utilization rises to this percentage, the
Safeguard Engine mechanism will initiate.

falling <value 20-100> - The user can set a percentage value of
the falling CPU utilization which will trigger the Safeguard Engine
function to cease. Once the CPU utilization falls to this percentage,
the Safeguard Engine mechanism will shut down.
trap_log [enable | disable] – Choose whether 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:

strict – 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.

fuzzy - 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.
Only Administrator-level users can issue this command.
