Abstract
This memo defines a Management Information Base (MIB) module that
contains Textual Conventions and OBJECT-IDENTITIES for use in
definitions of management information for IP Over InfiniBand
(IPOVERIB) networks. The intent is that these TEXTUAL
CONVENTIONs (TCs) will be imported and used in IPOVERIB related
MIB modules.

Internet-Draft IPOVERIB TC MIB Module June 2006
1. Introduction
This memo defines a portion of the Management Information Base for
use with network management protocols in the Internet community.
In particular, it defines Textual Conventions used in IETF IPOVERIB
and IPOVERIB-related MIBs.
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].
For an introduction to the concepts of InfiniBand, see [IBTAARCH].
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].

DESCRIPTION
"Identifies an InfiniBand (IB) Port. The InfiniBand
Architecture (IBA) defines a maximum of 254 physical ports
numbered Port 1 to Port 254. A port is the location on a
Channel Adapter, IB Router, or IB Switch to which a link is
connected. If a device has N ports, the physical ports are
always numbered from 1 to N. The relationship between an
InfiniBand port and an ifIndex is one-to-one. As such, the
value of an ifIndex object instance can be directly used to
identify corresponding instances of the objects defined
herein as IB ports. Note: this definition does include
enhanced switch port 0 but not base switch port 0. In the
case of a switch with enhanced switch port 0, the ifIndex is
offset by 1 from the ibPort. In all other cases, the ifIndex
is identical to the ibPort."

subnet prefix and the port's GUID. It is unique in the
InfiniBand fabric. NOTE: An IPOIB interface may have more
than 1 GID associated with it.
The Queue Pair Number field is a 3 octet field (octets 17,
18, & 19) that identifies the destination queue pair. Note:
The reserved field and the QPN field are collectively
referred to as the interface-id. If an IPOIB interface has
only 1 GID associated with it, the interface-id MAY contain

4. 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.
5. 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 1 } to the
IB-TC-MIB specified in this document.
