EFM Bonding Protection Definition
EFMBondingProtectionisaLayer2applicationusedtoprotecttrafficcarriedbythoseaccess
modulesthatincludeanEFMBondingEngineaspartoftheirfeatureset.EFMBonding
Protectionwillnotworkforaccessmodulesthatdonothavethisfeature.ThepurposeofEFM
Bondingisthe
protectionoftrafficgoingtoandfromaparticularslot,andnottheaccess
moduleinthatslot.
InanEFMBondingProtectionconfiguration,theTotalAccess5000EFMProtectModuleis
installedinaTotalAccess5000shelf.Oncethemoduleisinstalled,itmustbeconfiguredsoit
can
protecttrafficgoingtoandfromamoduleinaspecificslot.BycreatinganEFMBonding
Group,traffictoandfromagroupofslots/accessmodulescanalsobeprotected.Asanadded
feature,EFMBondingProtectionalsoallowseachofthesegroupsand/oraccessmodules
withinagroup
tohaveapriorityassignedtothetrafficgoingtoandfromthataccessmodule
orgroup.Forexample,assumethatalltheaccessmodulesarebeingprotectedbytheEFM
ProtectModuleinslot11.Theaccessmodulesinslot1to8havetheirprioritysetto1(priority

levelsrangefrom1to32where32isthehighestpriority),andthoseaccessmodulesinslots17
to21haveaprioritylevelof10.Ifoneoftheaccessmodulesinslots1to8goesoffline,their
trafficwillswitchovertotheEFMProtectModule.
Thetrafficwillcontinuetopassthrough
theEFMProtectModuleuntiltheaccessmodulethatwentofflinecomesbackonline,oran
accessmoduleinslots17to21goesoffline.Ifthatoccurs,theEFMProtectModulewillswitch
totheslot/accessmodulewiththehigherpriority.
