Configuring Port Traffic Rate Limiting
Purpose
TolimittherateofinboundtrafficontheSecureStackC2deviceonaperport/prioritybasis.The
allowablerangefortheratelimitingis64kilobytespersecondminimumuptothemaximum
transmissionrateallowableontheinterfacetype.
Ratelimitisconfiguredforagivenportandlist
ofpriorities.Thelistofprioritiescanincludeone,
some,oralloftheeight802.1pprioritylevels.Onceconfigured,therateofalltrafficenteringthe 
portwiththeprioritiesconfiguredtothatportisnotallowedtoexceedtheprogrammedlimit.If
therateexceedstheprogrammedlimit,frames
aredroppeduntiltheratefallsbelowthelimit.
