Abstract This document defines objects for managing Operations, Administration, and Maintenance (OAM) capabilities on Ethernet-like interfaces conformant to the Ethernet OAM functionality defined in [802.3ah]. The Ethernet OAM functionality is complementary to SNMP management in that it is focused on a small set of link-specific functions for Ethernet interfaces. This document defines objects for controlling those link OAM functions, and on providing mechanisms to take status and input from Ethernet OAM and feed it into a larger TCP/IP network management system.

Introduction The IEEE 802.3ah Ethernet in the First Mile (EFM) task force added new management capabilities to Ethernet like interfaces. These management capabilities were introduced to provide some basic OAM function on Ethernet media. The defined functionality includes discovery, error signaling, loopback, and link monitoring. This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community to manage these new EFM interface capabilities. 2. The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). M. Squire Expires - December 2004 [Page 2] EFM OAM MIB June 2004 Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 3. Overview Ethernet networks have evolved over the past 30 years from simple LANs to a variety of other applications, including wide area networks. To address some of these emerging markets, the IEEE 802.3ah task force defined additional clauses for the IEEE 802.3 standard [802.3-2002] to better address Ethernet deployments in the public access network. The Ethernet in the First Mile (EFM) task force was focused on four somewhat independent objectives to better address Ethernet access deployments: optics, copper, Ethernet passive optical networks (Ethernet PON, or EPON), and operations, administration, and maintenance (OAM). The optics sub-taskforce developed new optical physical layers that better served the long-reach outside plant networks typically found in the access network, including developing physical layers that operate up to 20Km and supporting the environmental conditions of outside deployments. The copper sub taskforce developed two new physical layers that run Ethernet natively over existing twisted pair wires that have been supporting voice services for decades. The EPON sub-taskforce developed a new point-to-multipoint Ethernet physical layer, utilizing Ethernet framing natively over a time-division multiple-access (TDMA) infrastructure. The OAM sub-taskforce introduced some basic management functionality into an Ethernet link to better monitor and maintain Ethernet networks in geographically disparate networks. This document defines the management objects necessary to integrate Ethernet OAM functionality into the SNMP management framework. Ethernet OAM is composed of a core set of functions and a set of optional functional groups that are not required to be implemented along with the core set. The mandatory functions include discovery operations (determining if the other end of the link is OAM capable, and what OAM functions it implements), state machine implementation, and some critical event flows. The optional functional groups are for (a) link events, (b) remote loopback, and (c) variable retrieval and response. Each optional functional group is controlled by a separate MIB table(s). Ethernet OAM is complementary, not competitive, with SNMP management in that it provides some basic management functions at layer two, M. Squire Expires - December 2004 [Page 3] EFM OAM MIB June 2004 rather than using layer three and above as required by SNMP over an IP infrastructure. Ethernet OAM provides single-hop functionality in that it works only between two directly connected Ethernet stations. SNMP can be used to manage the Ethernet OAM interactions of one Ethernet station with another. Ethernet OAM has three functional objectives which are detailed in the following sections. 3.1 Remote fault indication Remote fault indication provides a mechanism for one end of an Ethernet link to signal the other end that the receive path is non operational. Some Ethernet physical layers offer mechanisms to signal this condition at the physical layer. Ethernet OAM added a mechanism so that some Ethernet physical layers can operate in unidirectional mode, allowing frames to be transmitted in one direction even when the other direction is non-operational. Traditionally, Ethernet PHYs do not allow frame transmission in one direction if the other direction is not operational. Using this mode, Ethernet OAM allows frame-based signaling of remote fault conditions while still not allowing higher layer applications to be aware of the unidirectional capability. This document includes mechanisms for capturing that information and reflecting such information in objects and notifications into the SNMP management framework. 3.2 Link monitoring Ethernet OAM includes event signaling capability so that one end of an Ethernet link can indicate the occurrence of certain important events to the other end of the link. This happens via a layer two protocol. This document defines methods for incorporating the occurrence of these layer two events, both at the local end and far end of the link, into the SNMP management framework. Ethernet OAM also includes mechanisms for one Ethernet station to query another directly connected Ethernet station about the status of its Ethernet interface variables and status. This document DOES NOT include mechanisms for controlling how one Ethernet endpoint may use this functionality to query the status or statistics of a peer Ethernet entity. 3.3 Remote loopback Remote loopback is a link state where the peer Ethernet entity echoes every received packet (without modifications) back onto the link. Remote loopback is intrusive in that the other end of the link is not forwarding traffic from higher layers out over the link. This M. Squire Expires - December 2004 [Page 4] EFM OAM MIB June 2004 document defines objects controlling loopback operation and reading the status of the loopback state. 4. Relation to the Other MIBs The definitions presented here are based on Clauses 30 and 57 of [802.3ah]. Note that these clauses describe many of these variables and their affects on the MAC layer. In some cases there is a one-to one relationship between an object in this document and an object in the Clause 30 MIB of [802.3ah]. In other cases, the objects of this document reflect a more complex entity and are reflected by more than one objectx in the Clause 30 MIB of [802.3ah]. 4.1 Relation to other SNMP MIBs This objects defined in this document do not overlap with MIB-2 [RFC1213], the interfaces MIB [RFC2863], or the Ethernet-like interfaces MIB [RFC3635]. The objects defined here are defined for Ethernet-like interfaces only and use the same ifIndex as the associated Ethernet interface. This document is independent of the other MIBs derived from [802.3ah] for copper [802.3ah-copper] and EPON [802.3ah-epon]. 4.2 IANA Considerations The EFM OAM MIB requires the allocation of a single object identifier for its MODULE-IDENTITY under the MIB-2 tree. IANA has not yet allocated this object identifier. 4.3 Mapping of IEEE 802.3ah Managed Objects This section contains the mapping between managed objects defined in [802.3ah] Clause 30, and managed objects defined in this document.

MIB Structure The common EFM MIB objects of this memo focus on the OAM capabilities introduced in IEEE 802.3ah. The MIB objects are partitioned into four (4) different MIB groups. The dot3OamTable group manages the primary OAM objects of the Ethernet interface. This group controls the state and status of OAM as well as the mode in which it operates. The dot3OamStats table maintains statistics on the number and type of Ethernet OAM frames being transmitted and received on the Ethernet interface. The dot3OamPeer table maintains the current information on the status and configuration of the peer OAM entity on the Ethernet interface. Managed information includes the capabilities and function available on the peer OAM entity. The dot3OamEvent table defines the management objects for the event notification capability available in IEEE P802.3ah OAM. With IEEE P802.3ah OAM, one device may send notifications to its peer devices whenever an important event happens on the local device. 6.

The functionality presented here is based on IEEE P802.3ah/D3.3 [802.3ah], released in April, 2004. In particular, this MIB focused on the changes to Clause 30 of the draft that are not specific to any physical layer.

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 dot3OamAdminState. 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 (dot3OamMode) 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 (dot3OamMode) 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 M. Squire Expires - December 2004 [Page 12] EFM OAM MIB June 2004 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 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.

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).

Security Considerations The readable objects in this module can provide information about network traffic, and therefore may be considered sensitive. In particular, OAM provides mechanisms for reading the IEEE 802.3 Clause 30 MIB attributes from a link partner via a specialized layer two protocol. Unlike SNMP, IEEE P802.3ah OAM does not include encryption or authorization mechanisms. It should be used in environments where either this interface information is not considered sensitive, or where the facility terminations are protected. By default, OAM is disabled on Ethernet-like interfaces and is therefore not a risk. IEEE 802.3ah OAM is designed to support deployment in access and enterprise networks. In access networks, one end of a link is the CO-side, and the other is the CPE-side, and the facilities are often protected in wiring cages or closets. In such deployments, it is often the case that the CO-side is protected from access from the CPE side. Within IEEE P802.3ah OAM, this protection from remote access is accomplished by configuring the CPE-side in passive mode using the dot3OamMode attribute. This prevents the CPE from accessing functions and information at the CO-side of the connection. In enterprise networks, read-only interface information is often considered non-sensitive. M. Squire Expires - December 2004 [Page 54] EFM OAM MIB June 2004 The operation of OAM on an Ethernet interface does not adversely affect data traffic as OAM is a slow protocol with very limited bandwidth potential, and it is not required for normal link operation. And although there are a number of objects in this module with read-write or read-create MAX-ACCESS, they only affect the operation of the OAM protocol itself and not user data traffic. The loopback capability of OAM can have potentially disruptive effects in that the when enabling remote loopback, the remote station automatically transmits all received traffic back to the local station except for OAM traffic. This completely disrupts all higher layer protocols such as bridging, IP, and SNMP. Therefore an attribute (dot3OamLoopbackIgnoreRx) was introduced to control whether the local station processes or ignores received loopback commands. SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and GET/SET (read/change/create/delete) the objects in this MIB module. It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to indeed GET or SET (change/create/delete) them 8.
