The OAM functions supported on this Ethernet like interface.
OAM consists of separate functionality sets above the basic
discovery process. This value indicates the capabilities of
the peer OAM entity with respect to these functions. This
value is initialized so all bits are clear, and is invalid if
the h3cDot3OamPeerStatus is inactive.
The capbilities of the OAM peer can be determined from the
configuration field of the Local Information TLV of the most
recently received Information OAMPDU with a Local Information
TLV.
An Information OAMPDU is indicated by a valid frame with (1)
destination MAC address equal to that of the reserved MAC
address for Slow Protocols (See 43B of [802.3ah]), (2) a
lengthOrType field equal to the reserved type for Slow
Protocols, (3) a Slow Protocols subtype equal to that of the
subtype reserved for OAM, and (4) a OAM code that equals the
code reserved for Information OAMPDUs.
