xStack DES-6500 Modular Layer 3 Chassis Ethernet Switch CLI Manual
config safeguard_engine
Purpose Used to configure the Safeguard Engine settings for the Switch.
Syntax
config safeguard_engine {state [enable | disable] | utilization
{rising <value 20-100> | falling <value 20-100> | trap_log
[enable | disable} | mode [strict | fuzzy]}
Description This command is used to configure the settings for the Safeguard
Engine function of this Switch, based on CPU utilization.
Parameters 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:
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:
Restrictions Only administrator-level users can issue this command.
• 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.
• 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.
Example usage:
To configure the Switch for the Safeguard Engine.
