Connectivity Fault Management (CFM) is defined by IEEE 802.1ag, which is a standard for detecting, isolating and
reporting connectivity faults in a network. CFM is an end-to-end p er-service-instance Ethernet layer operation,
administration, and management (OAM) function. CFM functions i nclude path discovery, fault detection and fault
verification and isolation as defined by 802.1ag.
Ethernet CFM frames have a special Ether Type (0x8902). All CFM m essages are conf ined to a m aint enanc e dom ain
per VLAN basis. There are different message types which are identified b y unique Opcode of the CFM frame payload.
CFM message types that are supported include; Continuity Check Message (CCM) , Loopback Message and
Response (LBM, LBR) and Linktrace Message and Response (LTM and LT R).
