Rules for Provisioning EVCs, EVC Maps, and Policers
Toensurevalidprovisioning,therulesbelowareenforcedforEVCs,EVCmaps,andpolicers.
Inmostcasesthevalueofthestatusattributeforanentityprovidesabriefdescriptionofthe
condition.
1. AnEVC,EVCmap,orpolicerisappliedonlyiftherespectivestatusisrunning,which
indicates
thattheconditionsarevalid.
2. TwoEVCmapsareconsideredtobeduplicateiftheybothhavethesamevaluesforthe
followingattributes:
•UNIport
•CE‐VLAN‐ID
•OverlappingrangeforCE‐VLAN‐Pri
•DSCPvalue
• Untagged/Priority‐taggedframes
3. TwoEVCsareconsideredtobeduplicateiftheybothhavethesamevalues
forthe
followingattribute:
•S‐tag
4. TwoPolicersareconsideredtobeduplicateiftheybothhavethesamevaluesforthe
followingattributes:
•Mode
•UNI
•EVC
5. NoEVCmapscanhavethesamename.
6. NotwoEVCscanhavethesamename.
7. Notwopolicerscanhavethesamename.
8. Ifthenetworkelementis
managedthroughaVLANonadesignatedEFMbonding
grouporEthernetportforaportconnectedtobythesystemmanagementEVCasaMEN
port,thefollowingapplies.
•AnyEVCconnectedtothesameMENportwithans‐tagVIDvalueequaltothe
managementVIDvalueis
invalid.
•IfnoEVCsareconnectedtotheport,anyEVCmapsharingthesameportbut
connectedtoitasaUNIismadeinvalidiftheEVCmapismatchingonaCE‐VLAN‐
IDequaltotheVIDofthesystemmanagementEVC.
Ifaportisconnected
tothesystemmanagementEVCasaUNI,itcannotbeusedbyany
EVCsorEVCmaps.
9. IftheCE‐VLAN‐IDpreservationattributeofanEVCisdisabled,alloftheassociated
EVCmapsmusthavethesamevalueoftheCE‐VLAN‐IDattribute.
10. WhenmultipleEVCmapsare
appliedtoacommonEVC,eachEVCmapmusthavethe
sameUNI.MultipleUNIscannotbemappedtoacommonEVC.
11. IftwoEVCmapshavethesameUNI,onlyoneoftheEVCmapscanbeprovisionedto
allowuntaggedandprioritytaggedframes.
12. NooneEthernetframecan
begovernedbymorethanonepolicer.
