OPERATIONS, ADMINISTRATION, MAINTENANCE (OAM)
OAM is a general term used in network management and typically applied to a series of
standard protocols for installing, monitoring, and troubleshooting Metropolitan Area
Networks (MANs).
When applied to Ethernet, OAM is typically assumed to refer to the layer 2 (MAC layer),
management protocols (specifically 802.3ah and 802.1ag). Layer 2 management protocols
do not need higher level transport protocols to operate, OAM data is transferred in
standard multicast Ethernet frames.
802.3ah OAM:
(LINK-OAM)
A point-to-point protocol designed to verify a specific link between
two directly connected devices (over copper or fiber), that support
802.3ah OAM. One device must be configured as an active OAM
device; the other as passive (typically a core switch would be the
active device; the end device passive). 802.3ah OAM provides
link status, remote fault detection and the ability to initiate a
loopback circuit.
802.1ag:
(SERVICE-OAM)
Often referred to as Connectivity Fault Management (CFM), is an
end-to-end protocol designed to verify a specific network path
between two devices that may be in different geographical
locations. CFM allows the network operator to administer, monitor
and debug the network using continuity check (a “heart beat”
message), link trace (similar to traceroot, but operating at the
MAC layer) and loopback (can be likened to a layer 2 ping).
