Configuring Flow Setup Throttling (FST)
About FST
FlowSetupThrottling(FST)isaproactivefeaturedesignedtomitigateDoSattacksbeforethe
viruscanwreakhavoconthenetwork.FSTdirectlycombatstheeffectsofDoSattacksbylimiting
thenumberofneworestablishedflowsthatcanbeprogrammedonanyindividualswitchport.
Thisisachieved
bymonitoringthenewflowarrivalrateand/orcontrollingthemaximumnumber
ofallowableflows.
FSTlimitsthevulnerabilityofconnectionattacksonthe networkbyallowingadministratorsto:
• GloballyenableFSTontheswitchandonaport‐by‐portbasis.
• Configurethemaximumflowsallowedperuserclassification(port
type)andtheactionsthat
willoccurwhenflowlimitsarereached.
• Assignauserclassificationtoeachinterface.
• ControlthegenerationofSNMPnotifications.
• Controlthetime(inseconds)towaitbeforegeneratinganothernotificationofthesametype
onthesameinterface.
• Controllinkstatus.
