Cisco ME 3400 Ethernet Access Switch Software Configuration Guide

OL-9639-07

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. It also supports 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 be 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.

For complete command and configuration information for CFM, see the Cisco IOS feature module at

For complete syntax of the Ethernet OAM manager commands used in this chapter to configure CFM

and E-LMI interaction, see the command reference for this release.

For complete command and configuration information for the Ethernet OAM protocol, see the Cisco IOS

feature module at this URL:
