I am trying to test CFM Link monitoring in the openvswitch.
My Test Setup is given Below:
(port P1) -----------(port2) Linux bridge(port p3) ---------------(port p4)
P1 - Linux server 1 with ovs
P2 & P3 - Linux server 2 and normal linux bridge
P4 - Linux server 3 with ovs
Configured CFM in the linux_machine_1 and Linux_machine_3 using the below
Linux_server1 : ovs-vsctl set Interface eth0 cfm_mpid=4000
Linux_server3 : ovs-vsctl set Interface eth0 cfm_mpid=5000
When I shut one of the bridge interface in Linux server 2, I am able to see the
fault notification like below
2017-08-08T11:08:53.904Z|00003|cfm(monitor19)|INFO|enp4s0f2: CFM faults changed
from  to [recv].
This fault detection was done using CCM(continuity Check message) protocol.
Ethernet CFM/OAM supports Loopback protocol(LBM) and Link Trace protocol(LTM),
Is ovs is supporting these two protocols as well, if so could you please
describe how to use these two protocols.
I am using ovs 2.5 version.
