Ethernet CFM and Ethernet OAM Interaction
You can also configure the OAM Manager infrastructure for interaction between CFM and Ethernet
OAM. When the Ethernet OAM Protocol is running on an interface that has CFM MEPs configured,
Ethernet OAM informs CFM of the state of the interface. Interaction is unidirectional from the Ethernet
OAM to the CFM Protocol, and the only information exchanged is the user network interface port status.
The Ethernet OAM Protocol notifies CFM when these conditions occur:
• Error thresholds are crossed at the local interface.
CFM responds to the notification by sending a port status of Local_Excessive_Errors in the Port
StatusType Length Value (TLV).
• Ethernet OAM receives an OAMPDU from the remote side showing that an error threshold is
exceeded on the remote endpoint.
CFM responds to the notification by sending a port status of Remote_Excessive_Errors in the Port
Status TLV.
• The local port is set into loopback mode.
CFM responds by sending a port status of Test in the Port Status TLV.
• The remote port is set into loopback mode.
CFM responds by sending a port status of Test in the Port Status TLV.
