Example #3: Ingress Bandwidth Policer per Custom
AsinglebandwidthpolicercanbeappliedtoingressframesofaparticularEVCmaporsetof
EVCmaps.Usethisapplicationofthebandwidthpolicertolimittrafficoningressframes
withouthavingtospecifytheUNIorEVC.Thecustompolicermakesitpossibletolimittraffic
on
EVCmapsthathaveCE‐VLANsasthecriteria.Italsoallowsimplementingdifferent
policersonEVCmapsthathaveacommonconnectedtoanEVCbutarenotduplicateEVC
maps.
Considertheconditionsof“Example#2:TwoCE‐VLANsMappedtoOneEVC”onpage F‐11
wheretwoCE
‐VLANsarereceivedatthesameUNIportandmappedtothesameEVC.In
ordertoenforceadifferentbandwidthpolicerforeachCE‐VLAN,applyseparatecustom
policerstoeachEVCmap.
ThefollowingpolicerscanapplytotherespectiveEVCmaps.
