IP Over InfiniBand (IPOIB) MIBs
The IPOIB working group charter states that the
group will specify the set of MIB objects
required to allow the management of the
InfiniBand protocol for use with network
management protocols in TCP/IP-based
internets. The IPOIB Working Group web site
is http//www.ietf.org/html.charters/ipoib-chart
er.html

IPOIB MIBs (continued)

• There are six IPOIB MIBs currently defined in the
  WG
• IPOIB Textual Conventions MIB
• Definition of Textual Conventions and
  OBJECT-IDENTITIES for IP Over InfiniBand
  (IPOVERIB) Management
• IPOIB InfiniBand Interfaces MIB
• Definitions of Managed Objects for InfiniBand
  Interface Type
• IPOIB Subnet Management Agent MIB
• Definitions of Managed Objects for the
  Infiniband Subnet Management Agent (SMA)

Textual Conventions MIB

• Describes the Textual Conventions and
  OBJECT-IDENTITIES for IPOIB SNMP management.
• The purpose of this MIB is to create a common
  repository for the IPOIB Textual Conventions.
• Defines infinibandMIB node as experimental
  117.
• Currently contains 10 TEXTUAL-CONVENTION macros.
• More TCs to be added as needed.
• Current I-D draft-ietf-ipoib-ibmib-tc-mib-01.txt

7
InfiniBand Interfaces MIB

• Describes the managed objects for managing
  IBA-defined InfiniBand interfaces.
• The purpose of this MIB is to augment the
  standard SNMP Interface MIB (RFC 2863).
• Defines standard InfiniBand port ifType as
  infiniband(199).
• It contains an InfiniBand Port statistics table,
  a Virtual Lane Traffic Table for each ports VLs,
  and a table for the IPOIB Link layer addresses
  (20-octet value that uniquely identifies each
  IPOIB client end-point, i.e., QPN GID).
• Current I-D draft-ietf-ipoib-ibif-mib-03.txt

8
Subnet Management Agent MIB

• Describes the objects for managing InfiniBand
  Subnet Management Agents (SMA).
• The purpose of this MIB is to define the objects
  necessary to manage the SMA resident on the
  ManagedSystemElement.
• It contains information about the Node, Switch,
  GUIDs, IB Management and Data ports, P Keys, SL
  to VL mapping, linear, multicast, and random
  forwarding, Subnet Manager, vendor diagnostics,
  LEDs, and SMA traps.
• Current I-D draft-ietf-ipoib-subnet-mgmt-agent-mi
  b-03.txt

9
Channel Adapters MIB

• Describes the objects for managing the InfiniBand
  Channel Adapters.
• The purpose of this MIB is to define the objects
  necessary to manage Channel Adapters (HCAs and
  TCAs).
• This includes general CA information, CA
  attributes, CA port attributes, and the
  associated CA port GID info.
• Version 03 model contains multiple CAs per
  ManagedSystemElement.
• Needs to be augmented to include information
  derivable from Query HCA Transport Verb.
  Additional objects?
• Current I-D draft-ietf-ipoib-channel-adapter-mib-
  03.txt

10
Baseboard Management MIB

• Describes the objects for managing the InfiniBand
  Baseboard Management Agents (BMA).
• The purpose of this MIB is define the objects
  necessary to manage a BMA resident on the
  ManagedSystemElement.
• Distinguishes between Module, Non-Module, and
  Managed Chassis BMAs.
• Includes information on the Baseboard Management
  Unit, the B Key group, and the Vital Product Data
  (VPD) group. (Mainly derived from IBTA Vol. 2
  Chapter 13 Hardware Management).
• Current I-D draft-ietf-ipoib-baseboard-mgmt-agen
  t-mib-00.txt

11
Performance Management Agent MIB

• Describes the objects for managing InfiniBand
  Performance Management Agents (PMA).
• The purpose of this MIB is to define objects to
  manage each PMA on the ManagedSystemElement and
  to expose the sample counters to external SNMP
  management applications.
• Models both mandatory and optional running and
  sample counters.
• Issues with initial version SYNTAX of counters,
  SNMP vs. IB counter behavior, interaction of SNMP
  agent with Performance Manager and PMA, API to
  PM, others.
• Current I-D draft-ietf-ipoib-perf-mgmt-agent-mib-
  00.txt

Next Steps?

• Interest in defining new MIBs for WG effort?
  Subnet Administration MIB, Other General Service
  Agent MIBs (e.g., Device MIB, Communication
  (Connection) MIB, etc.), Subnet Manager MIB,
  others?
• Update I-Ds to new 1.1 IBTA Specification.
• Advance current MIB work. Need thorough review
  of current IPOIB MIBs.
• Gather implementation experience about any of
  the IPOIB MIBs. Send comments to mailing list
  please (ipoverib_at_ietf.org).
• Interest in a IPOIB Management Overview doc
  (possible Informational RFC track)?
• Advance certain IPOIB MIB Internet-Drafts to WG
  Last Call?
