NetVanta 800/8000 Series NCTE Configuration Procedure

CreatetheMD,MA,andaMEPontheNetvanta800/8000SeriesNCTE#1(exampleatthe

end):

1. FromtheEnableprompt,type

configure terminal,andpressENTERtoaccesstheGlo‐

balConfigurationprompt.

2. FromtheGlobalConfigurationprompt,enabletheEthernetOAMsubsystembytyping

ethernet cfm,andpressENTER.

3. FromtheGlobalConfigurationprompt,createtheEthernetOAMMDbytyping

ethernet cfm domain char-string WORD level <0-7>,andpressENTER

UsethenameoftheMDinplaceoftheWORDfieldandspecifythelevelofMDafterthe

levelargument.

4. FromtheMDConfiguration,type

association char-string WORDtocreatetheMA

(oreditanexistingMA).

5. FromtheMAConfigurationprompt,type

ccm interval [1-minute|1-second|10-

minutes|10-seconds|100-milliseconds]

tosettheCCMinterval(defaultis1

second):

Use100‐milliseconds,1‐second,10‐seconds,1‐minute,or10‐minutesfortheCCM

interval.

6. TheNetVantasupportsremoteMEPauto‐discoveryandauto‐learningwithinaMA.

Auto‐discoveryletsalocalMEPdiscoveritspeerswithoutcommittingthemto

astate

wheretheycancauseRemoteCCMdefects/alarms.OtheralarmsforinvalidCCI,

MACstatus,orXconnectwillstillberaised.Discoverydoesnotcommitanyofthe

discoveredRMEPstoprovisioningandifaDiscoveredentryfails,itwillberemoved

fromthesystemafteragingout.Learningallowstheuser

toimmediatelylearnallpeers,

transitionthemtoStaticentries,andplacetheirvaluesinprovisioningsotheywillbe

persistenuponarestore.

TherearesevealitemsthatcomposetheMEPdatabaseandcontrolhowitoperates.

•MEPDatabase‐EachMAmanagesitsownMEPdatabase.TheMEPdatabase

contains

• ConnectivityFailureInterval‐Thisvaluecannotbedirectlyconfiguredbyauserbut

isbasedoff oftheuser‐configurableCCMinterval.TheConnectivityFailureInterval

is3.5timestheCCMInterval.Itisoftenusedasthetimeframe

fromaRMEPanddoesn’treceivesubsequentCCMfromitwithinthistimeframe,

thentheRMEP’sstateissetto‘Fail’.ForaMaintenanceAssociationusinga1‐second
