OneoftheadvantagesofconfiguringtheBondingGroupsasdepictedinthisexampleis
relatedto“trafficprioritization”.Trafficprioritizationisusedtoestablishdifferentpriority
levelsfor trafficgoingtodifferentbonding groups.IfBG1hasanassignedpriorityof“5”,and
goesoffline,theEFMProtectionModule
willtakeoverthetrafficforthatmodule.Ifhowever,
BG2hasapriorityof“10”anditgoesoffline,theEFMProtectionModulewillswitchtothat

Provisioning Steps
ToenableEFMBondingProtection,completethefollowingprocedure:
1. FromtheEnableprompt,type
configure terminal,andpressENTERtoaccesstheGlo‐
balConfigurationprompt.
2. FromtheGlobalConfigurationprompt,type
protection-group <shelf/group>,
andpress
ENTERtoaccessthe ProtectionGroupConfigurat ionprompt.Ifitisanew
group,itiscreated.Ifitisanexistinggroup,itcannowbemodified.
3. FromtheProtection‐GroupConfigurationprompt,type
add protect-module
<slot>
,andpressENTERtoassigntheEFMProtectionModuletotheprotectiongroup.
4. FromtheProtection‐GroupConfigurationprompt,type
add working-module
<slot>
,andpressENTERtoassignaworkingaccessmoduleslottotheprotectiongroup.
5. Repeatstep4toaddallneededslotstotheprotectiongroup.
6. Bydefault,allslotsinthegroupareatlevel0,thelowestpriorityinthegroup.Thefirst
slotthatfailswillbeprotecteduntilitcan
havecontrolrestored.Otherslotswillbe
blocked.Togiveaslotprecedencewithinthegroup,type
priority <slot> <1-n>,
andpress
ENTER.32isthehighestpriority,followedby31,andsoon.
7. FromtheProtection‐GroupConfigurationprompt,type
wait-to-restore auto-
switch <1-20>
,andpressENTERtosetthewaittorestoretime.
ThisoptionisusedtosettheamountoftimethattheEFMProtectionmodulewill
continuetoprotecttrafficafteranaccessmodulethatwasdownhasbeenreturnedto
service.Oncetheaccessmoduleisbackinserviceforthetimeindicated
(1to20minutes),
andtherevertivesettingisenabled,theEFMProtectionmodulerelinquishesthetraffic
backtotheaccessmodule.
8. FromtheProtection‐GroupConfigurationprompt,type
endandpressENTERtoreturnto
theEnableprompt.
