Ethernet CFM Commands
Connectivity Fault Management (CFM) is the OAM Protocol provision for
end-to-end service layer OAM in carrier Ethernet networks. CFM provides
mechanisms to support the operator in performing connectivity checks, fault
detection, fault verification and isolation, and fault notification per service in
the network domain of interest. Unlike Ethernet OAM defined in IEEE
802.3ah, where the faults are detected and notified on a single point-to-point
IEEE Std. 802.3 LAN, this specification deals with the fault diagnosis at
service layer across networks comprising multiple LANs, including LANs
other than 802.3 media.
PowerConnect CFM supports the following functionality:
