DESCRIPTION
"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.
In particular, this MIB focused on the changes to Clause 30 of
the draft that are not specific to any physical layer. These
changes are primarily reflected in the new OAM features
developed under this project, that can be applied to any
Ethernet like interface. The OAM features are described in
Clause 57 of [802.3ah].
This mib is excerpted from the draft files directly,only changed
the object name,added the h3c as prefix.
The following reference is used throughout this MIB module:
[802.3ah] refers to:
IEEE Std 802.3ah-2004: 'Draft amendment to -
Information technology - Telecommunications and
information exchange between systems - Local and
metropolitan are networks - Specific requirements - Part
3: Carrier sense multiple access with collision detection
(CSMA/CD) access method and physical layer specifications
- Media Access Control Parameters, Physical Layers and
Management Parameters for subscriber access networks',
October 2004.
[802-2001] refers to:
'IEEE Standard for LAN/MAN (Local Area
Network/Metropolitan Area Network): Overview and
Architecture', IEEE 802, June 2001.

information retained by the system causes a transition to the
enabled(2) state.
Note that the value of this object is ignored when the
interface is not operating in full-duplex mode. OAM is not
supported on half-duplex links. "

DESCRIPTION
"At initialization and failure conditions, two OAM entities on
the same full-duplex Ethernet link begin a discovery phase to
determine what OAM capabilities may be used on that link. The
progress of this initialization is controlled by the OAM
sublayer.
This value is always disabled(1) if OAM is disabled on this
interface via the h3cDot3OamAdminState.
If the link has detected a fault and is transmitting OAMPDUs
with a link fault indication, the value is linkFault(2).
The passiveWait(3) state is returned only by OAM entities in
passive mode (h3cDot3OamMode) and reflects the state in which the
OAM entity is waiting to see if the peer device is OAM
capable. The activeSendLocal(4) is used by active mode
devices (h3cDot3OamMode) and reflects the OAM entity actively
trying to discover whether the peer has OAM capability but has
not yet made that determination.
The state sendLocalAndRemote(5) reflects that the local OAM
entity has discovered the peer but has not yet accepted or
rejected the configuration of the peer. The local device can,
for whatever reason, decide that the peer device is
unacceptable and decline OAM peering. If the local OAM entity
rejects the peer OAM entity, the state becomes
oamPeeringLocallyRejected(7). If the OAM peering is allowed
by the local device, the state moves to
sendLocalAndRemoteOk(6). Note that both the
sendLocalAndRemote(5) and oamPeeringLocallyRejected(7) states
fall within the state SEND_LOCAL_REMOTE of the Discovery state
diagram [802.3ah, Figure 57-5], with the difference being
whether the local OAM client has actively rejected the peering
or has just not indicated any decision yet. Whether a peering
decision has been made is indicated via the local flags field
in the OAMPDU (reflected in the aOAMLocalFlagsField of
30.3.6.1.10).
If the remote OAM entity rejects the peering, the state
becomes oamPeeringRemotelyRejected(8). Note that both the
sendLocalAndRemoteOk(6) and oamPeeringRemotelyRejected(8)
states fall within the state SEND_LOCAL_REMOTE_OK of the
Discovery state diagram [802.3ah, Figure 57-5], with the
difference being whether the remote OAM client has rejected
the peering or has just not yet decided. This is indicated
via the remote flags field in the OAM PDU (reflected in the
aOAMRemoteFlagsField of 30.3.6.1.11).
When the local OAM entity learns that both it and the remote
OAM entity have accepted the peering, the state moves to
operational(9) corresponding to the SEND_ANY state of the
Discovery state diagram [802.3ah, Figure 57-5]. "

"This object configures the mode of OAM operation for this
Ethernet like interface. OAM on Ethernet interfaces may be in
'active' mode or 'passive' mode. These two modes differ in
that active mode provides additional capabilities to initiate
monitoring activities with the remote OAM peer entity, while
passive mode generally waits for the peer to initiate OAM
actions with it. As an example, an active OAM entity can put
the remote OAM entity in a loopback state, where a passive OAM
entity cannot.
Changing this value results in incrementing the configuration
revision field of locally generated OAMPDUs (30.3.6.1.12) and
potentially re-doing the OAM discovery process if the
h3cDot3OamOperStatus was already operational(9). "

DESCRIPTION
"The loopback status of the OAM entity. This status is
determined by a combination of the local parser and
multiplexer states, the remote parser and multiplexer states,
as well as by the actions of the local OAM client. When
operating in normal mode with no loopback in progress, the
status reads noLoopback(1).
If the OAM client has sent an Loopback OAMPDU and is waiting
for a response, where the local parser and multiplexer states
are DISCARD (see [802.3ah, 57.2.11.1]), the status is
'initiatingLoopback'. In this case, the local OAM entity has
yet to receive any acknowledgement that the remote OAM entity
has received its loopback command request.
If the local OAM client knows that the remote OAM entity is in
loopback mode (via the remote state information as described
in [802.3ah, 57.2.11.1, 30.3.6.1.15]), the status is
remoteLoopback(3). If the local OAM client is in the process
of terminating the remote loopback [802.3ah, 57.2.11.3,
30.3.6.1.14], with its local multiplexer and parser states in
DISCARD, the status is terminatingLoopback(4). If the remote
OAM client has put the local OAM entity in loopback mode as
indicated by its local parser state, the status is
localLoopback(5).
The unknown(6) status indicates the parser and multiplexer
combination is unexpected. This status may be returned if the
OAM loopback is in a transition state but should not persist.
The values of this attribute correspond to the following
values of the local and remote parser and multiplexer states.

DESCRIPTION
"A count of the number of Loopback Control OAMPDUs transmitted
on this interface.
An Loopback Control 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) an OAMPDU code equals the
OAM Loopback Control code.
Discontinuities of this counter can occur at re-initialization
of the management system, and at other times as indicated by
the value of the ifCounterDiscontinuityTime. "
