DAS-3600 Series Ethernet over VDSL Switch CLI Reference Manual
To configure ARP storm control for system.
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 Safeguard Engine to minimize the effects of an ARP
storm.
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
messages to the device's SNMP agent and switch log once the Safeguard Engine has been
activated by a high CPU utilization rate.
mode [ strict | fuzzy] – 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 and Operator-level users can issue this command.
