Prior to this configuration, end-user need to

be familiar with the following modules:

• Ethernet Frame tructure

• !"#$%p&'

• CFM (heory

• witch Configuration

• )nterfaces Configuration

Agenda

• CFM: *hy+• Preliminary configuration

• etup eview

• Configuration Flow

• Configuration eview

• Manual P).

• Manual /in0trace

• 1utomatic /in0trace

CFM: WHY ?

• 2y definition, /3 )P or /# E(4 are Connection-less networ0s

• )n connection-less networ0s we are blind 5 unable to determine pac0et pathor latency

• (his ma0es troubleshooting and maintenance a harder tas0

• Solution: we need to convert our Connection-less networ0 into aConnection-6riented networ0

CFM: WHY ?

• Connection-6riented networ0s 71(M, )P&MP/8 enable administrators setting apre-defined pac0et path, reserving 2* per service, faster event detection and

thus 5 effective troubleshooting 9 maintenance

• uch technologies are too epensive and sometimes not feasible for Mobile6perators & Mobile 2ac0haul solutions

• olution: use a cheaper technology with enhanced features:

Connection-6riented

Ethernet Core ; 6perations, 1dministration 9 Maintenance support 7CFM8

CFM enables /3 operations

such as (raceroute and

P). with a simpler E(4

infrastructure
