13 Operation, Administration and Maintenance (OAM)
This chapter describes the Operation, Administration and Maintenance (OAM)
capabilities of the EtherHaul system and includes the following topics:
 Connectivity Fault Management (CFM) as per IEEE 802.1ag
 Link OAM as per IEEE 802.1ah
 Performance Monitoring as per Y.1731
OAM is a licensed feature that requires license for operation. Before configuring it,
verify that license is available and enable the L2 (oam) license component.

 Working with Maintenance Domains (MD)
 Working with Maintenance Associations (MA)
 Working with Component Maintenance Associations
 Working with Maintenance End Points (MEP)
 Working with Peer MEPs
 Working with CCM Messages
 Working with Link Trace Messages

13.1.1 CFM Overview
Connectivity Fault Management (CFM) is an Ethernet layer operation, administration,
and management (OAM) protocol designed to monitor and troubleshoot networks. CFM
enables to detect, verify, and isolate connectivity failures in virtual bridged local area
networks.
A Maintenance Domain (MD) is a part of a network that is controlled by a single
operator and used to support the connectivity between service access points. There are
eight hierarchical Maintenance Domain Levels (MD Level). Each CFM layer supports
Note:
OAM configuration and monitoring supported in the CLI only.
