Internet-Draft           IPOVERIB CA MIB Module           September 2005


1.  Introduction

   This document defines a MIB for InfiniBand Channel Adapters (CA).

   The InfiniBand Architecture [INFINIV1] (IBA) is defined by the
   InfiniBand Trade Association.  InfiniBand is designed to provide low
   latency, high bandwidth interconnect in a computing environment.
   This document will define the objects related to managing a specific
   class of InfiniBand nodes called Channel Adapters.

   A Channel Adapter (CA) is the end-point for IBA packets that are sent
   and received over the IBA switching fabric.  There are two types of
   CAs: Host Channel Adapters (HCA) and Target Channel Adapters (TCA).
   Typically, HCAs are used by host processors and TCAs are used by I/O
   adapters to connect to the IBA switch fabric.  The HCA supports the
   IBA Verbs layer as the transport layer interface, while the TCA often
   uses its own implementation-specific interface to the transport
   layer.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT"
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in
   this document are to be interpreted as described in
   RFC 2119 [RFC2119].


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).
   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.  Structure of the MIB

   This section describes the structure of the IPOIB CA MIB.

3.1.  Overview

   The SNMP management of the CA involves the monitoring of key channel
   adapter attributes.

3.2.  Discussion of MIB Groups

   The CA MIB is divided into two basic groups: MIB objects and the

   conformance group.

3.3.  The CA MIB Objects

   The CA MIB objects correlate to the set of Channel Adapter
   attributes.  These attributes are organized into three major CA MIB
   groups.

   These are: the General Channel Adapter Info Group, the Channel
   Adapter Attributes Info Group, and the Channel Adapter Port
   Attributes and Gid Info Group.

3.3.1.  The General Channel Adapter Info Group

   This group provides general information common to any InfiniBand
   network entity that contains CAs.  This includes distinguishing
   between the HCA and the TCA, displaying the node GUIDs, and showing
   the number of ports on each CA.

3.3.2.  The Channel Adapter Attributes Info Group

   This group provides more specific information about the CAs on a
   network entity.  This includes various attribute flags, transport
   service support, and other CA characteristics.

3.3.3. The Channel Adapter Port Attributes and Gid Info Group

   This group provides information about the CA ports.  This includes
   the type of physical interfaces supported, other port attributes,
   and a table containing the port GIDs.

3.4. The CA Conformance Group

   The CA Conformance Group lists the possible compliances for various
   types of InfiniBand nodes that contain channel adapters.  Currently,
   two types of compliance are defined: basic and full.  The units of
   conformance which define the constituent object groups are also
   listed.

3.4.1.  CA Compliance Groups

   The Compliance Groups list acceptable MIB implementation
   requirements.

5. Security Considerations

   This memo defines textual conventions and object identities for use
   in IPOVERIB MIB modules.  Security issues for these MIB modules are
   addressed in the memos defining those modules.  Because this memo
   does not define management objects, the memo has no impact on the
   security of the Internet.


6.  IANA Considerations

   IANA is requested to make a MIB OID assignment under the transmission
   branch, that is, assign the infinibandMIB under { transmission 199 }.
   This sub-id is requested because 199 is the ifType for
   infiniband(199) and is available under transmission.

   In the future, IPOIB related standards track MIB modules should be
   rooted under the infinibandMIB subtree.  The IANA is requested to

   manage that namespace.  New assignments can only be made via a
   Standards Action as specified in [RFC2434].

   This document also requests IANA to assign { infinibandMIB 4 } to the
   IB-CA-MIB specified in this document.
