CFM CCM support on PS interfaces

We support connectivity fault management (CFM) continuity check messages (CCM) on PS interface part of EVPN. You can configure:

• CCM for down maintenance association end points (MEPs), that are down, on the PS interface to monitor the Ethernet networks for connectivity faults.
• Remote defect indication (RDI) for the CCM frame.
• Action profile with action link down for the remote MEP to bring down the PS interface when connectivity is lost.
• Ethernet link trace (ETH-LT) and loopback (ETH-LB) are supported on the CFM session.
