Ethernet OAM CFM

Hi

I was configured CFM between c4948 and mx80.

(mx80#1-mep<---->mip-c4948#1-mip<--->mip-c4948#2-mip<---->mx80#2-mep)

Then i do traceroute ethernet from mx80#1 to mx80#2, some times i cann't seen MAC address of cisco-switch.

What is it mean?

I use IOS 15.0(2)SG

Some configuration:

ethernet cfm ieee

ethernet cfm global

ethernet cfm traceroute cache

ethernet cfm mip auto-create level 5 vlan 1-4094 sender-id chassis

ethernet cfm domain J-sw-J level 5

id dns J-sw-J

sender-id chassis

mip auto-create

service J-sw-J vlan 1 direction down

!

ethernet cfm logging

.......

interface GigabitEthernet1/1

ethernet cfm mip level 5 vlan 1-4094

!

interface GigabitEthernet1/2

ethernet cfm mip level 5 vlan 1-4094

!

Some command  output:

Switch#show ethernet cfm maintenance-points remote

Switch#

sh ethernet cfm mpdb
