Enable lm (loss measurement) and dm (delay measurement) on remote (Link and
Customer levels):
set cfm-mep 1 1 2 lm enabled
set cfm-mep 1 1 2 dm enabled
set cfm-mep 2 2 2 lm enabled
set cfm-mep 2 2 2 dm enabled
To monitor the loss and delay
show cfm-peer-mep 1 1 1 2 statistics <- to the peer
cfm-peer-mep 1 1 1 2 far-end-loss : 0
cfm-peer-mep 1 1 1 2 near-end-loss : 0
cfm-peer-mep 1 1 1 2 total-tx-far-end : 3178
cfm-peer-mep 1 1 1 2 total-tx-near-end : 3932
cfm-peer-mep 1 1 1 2 delay : 745
cfm-peer-mep 1 1 1 2 delay-variation : 320
cfm-peer-mep 1 1 1 2 elapsed-time : 0000:00:48:42

Link OAM
Link OAM, as defined in IEEE802.3ah, is an Ethernet layer operation, administration, and
management (OAM) protocol designed to monitor and troubleshoot networks. Link
OAM enables to detect, verify, and isolate connectivity failures in point-to-point
connections.
The following functionality is supported:
Discovery
Remote Loopback
13.3.1
Link OAM Configuration
Link OAM can be enabled on one of the link interfaces (Eth1, Eth2, Eth3 orEth4) or the
radio interface (Eth0).
To enable Link OAM:
set link-oam <eth-list> [admin <value>]
<eth-list> : eth0 | eth1 | eth2 | eth3 | eth4
[admin <value: Enabled | disabled >]
