Abstract
InfiniBand Architecture (IBA) specifies a high speed, channel based,
switched fabric architecture that delivers scalable performance in
data centers.
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it defines objects for managing InfiniBand Channel
Adapters (CA).

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"
Rosenstock Expires April 2007 [Page 2]
Internet-Draft IPOVERIB CA MIB Module October 2006
"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
Rosenstock Expires April 2007 [Page 3]
Internet-Draft IPOVERIB CA MIB Module October 2006
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.
