The subsequent articles describe the IEEE 802.1ag “Service OAM” function and how to set it up on your Metro Ethernet Network to perform end-to-end monitoring.

Service OAM (or CFM Connectivity Fault Management) encompasses fault management and performance management capabilities of the Cisco Provider Connectivity Assurance Sensor Control.

Note: The Sensor Control’s implementation of Service OAM is primarily focused on reflecting loopback message frames and delay measurements.

Note: The port status may become yellow under these circumstances:
EVC-FP (Ethernet Virtual Connection Fault Propagation)
ETH-CSF (Ethernet Client Signal Failure)
LLF-FP (Link Loss Forwarding Fault Propagation)

The following figure shows an overview of Service OAM.
