CFM

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 per-service-instance Ethernet layer operation, administration, and management (OAM) function. CFM functions include 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 messages are confined to a maintenance domain per VLAN basis. There are different message types which are identified by 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 LTR).

CFM Port Settings

This table is used to enable or disable the connectivity fault management function on a per port basis. CFM is disabled on all ports by default.
