Configuring Ethernet OAM, CFM, and E-LMI

Ethernet Operations, Administration, and Maintenance (OAM) is a protocol for installing, monitoring,

and troubleshooting Ethernet networks to increase management capability within the context of the

overall Ethernet infrastructure. The Cisco ME 3400 switch supports IEEE 802.1ag Connectivity Fault

Management (CFM), Ethernet Local Management Interface (E-LMI), and IEEE 802.3ah Ethernet OAM

discovery, link monitoring, remote fault detection, and remote loopback. Cisco IOS Release 12.2(40)SE

adds support for IP Service Level Agreements (SLAs) for CFM. Ethernet OAM manager controls the

interworking between any two of the protocols (CFM, E-LMI, and OAM).

Note The Cisco ME 3400 switch must running the metro IP access or metro access image to support Ethernet

OAM functions.

This chapter provides information about configuring CFM, E-LMI, and the Ethernet OAM protocol.
