The configuration revision of the OAM peer as reflected in
the latest OAMPDU. This attribute is changed by the peer
whenever it has a local configuration change for Ethernet OAM
this interface. This value is initialized to all zeros
(0x00000000), and is invalid if the h3cDot3OamPeerStatus is
inactive.
The configuration revision can be determined from the Revision
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.
