Configuring Ethernet OAM and CFM
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. Starting with Cisco IOS Release 15.0(2)SG, the Catalyst 4500 series
switch supports Standardized (Draft 8.1) IEEE 802.1ag Connectivity Fault Management (CFM) 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, and ITU-T Y.1731 fault management.
Ethernet OAM manager controls the interworking between CFM and 802.3ah OAM protocols.
This chapter provides information about configuring CFM and the Ethernet OAM protocol. It defines
the differences between the ratified CFM 802.1ag standard (draft 8.1) and the previous version supported
on the switch in Cisco IOS (draft 1.0). It also includes configuration information for CFM ITU-TY.1731
fault management support in this release.
For complete command and configuration information for Ethernet OAM, CFM, and Y.1731, see the
