UP MEPs and DOWN MEPs have been aligned as of this release to better emulate service data. When an UP MEP or DOWN MEP is the source of the ETH-CFM PDU the priority value configured, as part of the configuration of the MEP or specific test, will be treated as the Forwarding Class (FC) by the egress QoS policy. If there is no egress QoS policy the priority value will be mapped to the CoS values in the frame. However, egress QoS Policy may overwrite this original value. The Service Assurance Agent (SAA) uses fc fc-name to accomplish similar functionality.
UP MEPs and DOWN MEPs terminating an ETH-CFM PDU will use the received FC as the return priority for the appropriate response, again feeding into the egress QoS policy as the FC.
ETH-CFM PDUs received on the MPLS-SDP bindings will now correctly pass the EXP bit values to the ETH-CFM application to be used in the response.
These are default behavioral changes without CLI options.
