cdot3OamMIB 1.3.6.1.4.1.9.10.136
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. 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. [802.3-2002] refers to: IEEE Std 802.3-2002: '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', March 2002.

cdot3OamTable 1.3.6.1.4.1.9.10.136.1.1
This table contains the primary controls and status for the OAM capabilities of an Ethernet like interface. There will be one row in this table for each Ethernet like interface in the system that supports the OAM functions defined in [802.3ah].
OBJECT-TYPE    
  SEQUENCE OF  
    Cdot3OamEntry

cdot3OamEntry 1.3.6.1.4.1.9.10.136.1.1.1
An entry in the table, containing information on the Ethernet OAM function for a single Ethernet like interface. Entries in the table are created automatically for each interface supporting Ethernet OAM. The status of the row entry can be determined from cdot3OamOperStatus. A cdot3OamEntry is indexed in the cdot3OamTable by the ifIndex object of the Interfaces MIB.
OBJECT-TYPE    
  Cdot3OamEntry  

cdot3OamAdminState 1.3.6.1.4.1.9.10.136.1.1.1.1
This object is used to provision the default administrative OAM mode for this interface. This object represents the desired state of OAM for this interface. The cdot3OamAdminState always starts in the disabled(1) state until an explicit management action or configuration information retained by the system causes a transition to the enabled(2) state. When enabled(2), Ethernet OAM will attempt to operate over this interface.
OBJECT-TYPE    
  INTEGER disabled(1), enabled(2)  

cdot3OamOperStatus 1.3.6.1.4.1.9.10.136.1.1.1.2
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 cdot3OamAdminState. If the link has detected a fault and is transmitting OAMPDUs with a link fault indication, the value is linkFault(2). Also, if the interface is not operational (ifOperStatus is not up(1)), linkFault(2) is returned. Note that the object ifOperStatus may not be up(1) as a result of link failure or administrative action (ifAdminState being down(2) or testing(3)). The passiveWait(3) state is returned only by OAM entities in passive mode (cdot3OamMode) and reflects the state in which the OAM entity is waiting to see if the peer device is OAM capable. The activeSendLocal(4) value is used by active mode devices (cdot3OamMode) 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]. Since Ethernet OAM functions are not designed to work completely over half-duplex interfaces, the value nonOperHalfDuplex(10) is returned whenever Ethernet OAM is enabled (cdot3OamAdminState is enabled(1)) but the interface is in half-duplex operation.
OBJECT-TYPE    
  INTEGER disabled(1), linkFault(2), passiveWait(3), activeSendLocal(4), sendLocalAndRemote(5), sendLocalAndRemoteOk(6), oamPeeringLocallyRejected(7), oamPeeringRemotelyRejected(8), operational(9), nonOperHalfDuplex(10)  

cdot3OamMode 1.3.6.1.4.1.9.10.136.1.1.1.3
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. The default value of cdot3OamMode is dependent on the type of system on which this Ethernet like interface resides. The default value should be 'active(1)' unless it is known that this system should take on a subservient role to the other device connected over this interface. 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 cdot3OamOperStatus was already operational(9).
OBJECT-TYPE    
  INTEGER active(1), passive(2)  

cdot3OamMaxOamPduSize 1.3.6.1.4.1.9.10.136.1.1.1.4

cdot3OamFunctionsSupported 1.3.6.1.4.1.9.10.136.1.1.1.6
The OAM functions supported on this Ethernet like interface. OAM consists of separate functional sets beyond the basic discovery process which is always required. These functional groups can be supported independently by any implementation. These values are communicated to the peer via the local configuration field of Information OAMPDUs. Setting 'unidirectionalSupport(0)' indicates that the OAM entity supports the transmission of OAMPDUs on links that are operating in unidirectional mode (traffic flowing in one direction only). Setting 'loopbackSupport(1)' indicates the OAM entity can initiate and respond to loopback commands. Setting 'eventSupport(2)' indicates the OAM entity can send and receive Event Notification OAMPDUs. Setting 'variableSupport(3)' indicates the OAM entity can send and receive Variable Request and Response OAMPDUs.

  BITS unidirectionalSupport(0), loopbackSupport(1), eventSupport(2), variableSupport(3)  

cdot3OamPeerTable 1.3.6.1.4.1.9.10.136.1.2
This table contains information about the OAM peer for a particular Ethernet like interface. OAM entities communicate with a single OAM peer entity on Ethernet links on which OAM is enabled and operating properly. There is one entry in this table for each entry in the cdot3OamTable for which information on the peer OAM entity is available.

cdot3OamPeerMode 1.3.6.1.4.1.9.10.136.1.2.1.4
The mode of the OAM peer as reflected in the latest Information OAMPDU received with a Local Information TLV. The mode of the peer can be determined from the Configuration field in the Local Information TLV of the last Information OAMPDU received from the peer. The value is unknown(3) whenever no Local Information TLV has been received. The values of active(1) and passive(2) are returned when a Local Information TLV has been received indicating the peer is in active or passive mode, respectively.
OBJECT-TYPE    
  INTEGER active(1), passive(2), unknown(3)  

cdot3OamPeerMaxOamPduSize 1.3.6.1.4.1.9.10.136.1.2.1.5
The maximum size of OAMPDU supported by the peer as reflected in the latest Information OAMPDU received with a Local Information TLV. Ethernet OAM on this interface must not use OAMPDUs that exceed this size. The maximum OAMPDU size can be determined from the PDU Configuration field of the Local Information TLV of the last Information OAMPDU received from the peer. A value of zero is returned if no Local Information TLV has been received. Otherwise, the value of the OAM peer's maximum OAMPDU size is returned in this value. Note that the values 1..63 are invalid sizes for Ethernet frames and should never appear.

cdot3OamPeerConfigRevision 1.3.6.1.4.1.9.10.136.1.2.1.6
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. 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. A value of zero is returned if no Local Information TLV has been received.
OBJECT-TYPE    
  Unsigned32 0..65535  

cdot3OamPeerFunctionsSupported 1.3.6.1.4.1.9.10.136.1.2.1.7
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. If unidirectionalSupport(0) is set, then the peer OAM entity supports sending OAM frames on Ethernet interfaces when the receive path is known to be inoperable. If loopbackSupport(1) is set, then the peer OAM entity can send and receive OAM loopback commands. If eventSupport(2) is set, then the peer OAM entity can send and receive event OAMPDUs to signal various error conditions. If variableSupport(3) is set, then the peer OAM entity can send and receive variable requests to monitor attribute value as described in Clause 57 of [802.3ah]. The capabilities 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. All zeros are returned if no Local Information TLV has yet been received.

  BITS unidirectionalSupport(0), loopbackSupport(1), eventSupport(2), variableSupport(3)  

cdot3OamLoopbackTable 1.3.6.1.4.1.9.10.136.1.3
This table contains controls for the loopback state of the local link as well as indicating the status of the loopback function. There is one entry in this table for each entry in cdot3OamTable that supports loopback functionality (where cdot3OamFunctionsSupported includes the loopbackSupport bit set). Loopback can be used to place the remote OAM entity in a state where every received frame (except OAMPDUs) is echoed back over the same interface on which they were received. In this state, at the remote entity, 'normal' traffic is disabled as only the looped back frames are transmitted on the interface. Loopback is thus an intrusive operation that prohibits normal data flow and should be used accordingly.
OBJECT-TYPE    
  SEQUENCE OF  
    Cdot3OamLoopbackEntry

cdot3OamLoopbackEntry 1.3.6.1.4.1.9.10.136.1.3.1
An entry in the table, containing information on the loopback status for a single Ethernet like interface. Entries in the table are automatically created whenever the local OAM entity supports loopback capabilities. The loopback status on the interface can be determined from the cdot3OamLoopbackStatus object.
OBJECT-TYPE    
  Cdot3OamLoopbackEntry  

cdot3OamLoopbackStatus 1.3.6.1.4.1.9.10.136.1.3.1.1
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). The values initiatingLooopback(2) and terminatingLoopback(4) can be read or written. The other values can only be read - they can never be written. Writing initiatingLoopback causes the local OAM entity to start the loopback process with its peer. This value can only be written when the status is noLoopback(1). Writing the value initiatingLoopback(2) in any other state has no effect. When in remoteLoopback(3), writing terminatingLoopback(4) causes the local OAM entity to initiate the termination of the loopback state. Writing terminatingLoopack(4) in any other state has no effect. If the OAM client initiates a looopback and 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. value LclPrsr LclMux RmtPrsr RmtMux noLoopback FWD FWD FWD FWD initLoopback DISCARD DISCARD FWD FWD rmtLoopback DISCARD FWD LPBK DISCARD tmtngLoopback DISCARD DISCARD LPBK DISCARD lclLoopback LPBK DISCARD DISCARD FWD unknown *** any other combination ***

cdot3OamLoopbackIgnoreRx 1.3.6.1.4.1.9.10.136.1.3.1.2
Since OAM loopback is a disruptive operation (user traffic does not pass), this attribute provides a mechanism to provide controls over whether received OAM loopback commands are processed or ignored. When the value is ignore(1), received loopback commands are ignored. When the value is process(2), OAM loopback commands are processed. The default value is to ignore loopback commands (ignore(1)).

cdot3OamFramesLostDueToOam 1.3.6.1.4.1.9.10.136.1.4.1.17
A count of the number of frames that were dropped by the OAM multiplexer. Since the OAM multiplexer has multiple inputs and a single output, there may be cases where frames are dropped due to transmit resource contention. This counter is incremented whenever a frame is dropped by the OAM layer. Note that any Ethernet frame, not just OAMPDUs, may be dropped by the OAM layer. This can occur when an OAMPDU takes precedence over a 'normal' frame resulting in the 'normal' frame being dropped. When this counter is incremented, no other counters in this MIB are incremented.

cdot3OamEventConfigTable 1.3.6.1.4.1.9.10.136.1.5
Ethernet OAM includes the ability to generate and receive Event Notification OAMPDUs to indicate various link problems. This table contains the mechanisms to enable Event Notifications and configure the thresholds to generate the standard Ethernet OAM events. There is one entry in the table for every entry in cdot3OamTable that supports OAM events (where cdot3OamFunctionsSupported includes the eventSupport bit set). The values in the table are maintained across changes to cdot3OamOperStatus. The standard threshold crossing events are: - Errored Symbol Period Event. Generated when the number of symbol errors exceeds a threshold within a given window defined by a number of symbols (for example, 1,000 symbols out of 1,000,000 had errors). - Errored Frame Period Event. Generated when the number of frame errors exceeds a threshold within a given window defined by a number of frames (for example, 10 frames out of 1000 had errors). - Errored Frame Event. Generated when the number of frame errors exceeds a threshold within a given window defined by a period of time (for example, 10 frames in 1 second had errors). - Errored Frame Seconds Summary Event. Generated when the number of errored frame seconds exceeds a threshold within a given time period (for example, 10 errored frame seconds within the last 100 seconds). An errored frame second is defined as a 1 second interval which had >0 frame errors. There are other events (dying gasp, critical events) that are not threshold crossing events but which can be enabled/disabled via this table.
