The MIB module for managing the new Ethernet OAM features
introduced by the Ethernet in the First Mile task force (IEEE
802.3ah). The functionality presented here is based on IEEE
802.3ah [802.3ah], released in October, 2004. [802.3ah] was
prepared as an addendum to the standing version of IEEE 802.3
[802.3-2002] at the time. Since then, [802.3ah] has been
merged into the base IEEE 802.3 specification in [802.3-2005].
In particular, this MIB focuses on the new OAM functions
introduced in Clause 57 of [802.3ah]. The OAM functionality
of Clause 57 is controlled by new management attributes
introduced in Clause 30 of [802.3ah]. The OAM functions are
not specific to any particular Ethernet physical layer, and
can be generically applied to any Ethernet interface of
[802.3-2002].
An Ethernet OAM protocol data unit is a valid Ethernet frame
with a destination MAC address equal to the reserved MAC
address for Slow Protocols (See 43B of [802.3ah]), a
lengthOrType field equal to the reserved type for Slow
Protocols, and a Slow Protocols subtype equal to that of the
subtype reserved for Ethernet OAM. OAMPDU is used throughout
this document as an abbreviation for Ethernet OAM protocol
data unit.
