Internet-Draft RBridges: TRILL Base MIB December 3, 2012
1. Introduction
This document describes a model for managing RBridges (Routing
Bridges), also known as TRILL Switches, as defined in [RFC6325].
RBridges provide optimal pair-wise forwarding without configuration
using IS-IS routing and encapsulation of traffic. RBridges are
compatible with previous IEEE 802.1 customer bridges as well as IPv4
and IPv6 routers and end nodes. They are as invisible to current IP
routers as bridges are and, like routers, they terminate the bridge
spanning tree protocol. In creating an RBridge management model the
device is viewed primarily as a customer bridge. For a discussion of
the problem addressed by TRILL (Transparent Interconnection of Lots
of Links) see [RFC5556].
RBridges support features specified for transparent bridges in IEEE
802.1, and the corresponding MIB modules are used to manage those
features. For IS-IS purposes, the corresponding MIB module is used to
manage the protocol. This MIB module specifies those objects which
are TRILL-specific and hence not available in other MIB modules.
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,
which consists of [RFC2578], [RFC2579] and [RFC2580].
3. Overview
The RBridge MIB module is intended as an overall framework for
managing RBridges, also known as TRILL Switches. Where possible the
MIB references existing MIB definitions in order to maximize reuse.
This results in a considerable emphasis on the relationship with
other MIB modules.
Starting with the physical interfaces, there are requirements for
certain elements of the IF-MIB to be implemented. These elements are
required in order to connect the per-port parameters to higher level
functions of the physical device.
Transparent bridging, VLANs, Traffic classes and Multicast Filtering
Rijhsinghani & Zebrose Expires June 6, 2013 [Page 3]
Internet-Draft RBridges: TRILL Base MIB December 3, 2012
are supported by the TRILL protocol, and the corresponding management
is expected to conform to the BRIDGE-MIB [RFC4188], P-BRIDGE-MIB and
Q-BRIDGE-MIB [RFC4363] modules.
The IS-IS routing protocol is used in order to determine the optimum
pair-wise forwarding path. This protocol is managed using the IS-IS
MIB module defined in [RFC4444]. Since the TRILL protocol specifies
use of a single level and a fixed area address of zero, some IS-IS
MIB objects are not applicable. Some IS-IS MIB objects are used in
the TRILL protocol.
4. Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in RFC
2119 [RFC2119].
5. Structure of the MIB Module
Objects in this MIB module are arranged into subtrees. Each subtree
is organized as a set of related objects. The various subtrees are
shown below. These are supplemented with required elements of the IF-
MIB, ISIS-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB and IEEE Bridge
MIB modules.
5.1 Textual Conventions
Textual conventions are defined to represent object types relevant to
TRILL.
5.2 The rbridgeBase Subtree
This subtree contains system and port specific objects applicable to
all RBridges.
5.3 The rbridgeFdb Subtree
This subtree contains objects applicable to the Forwarding database
used by the RBridge in making packet forwarding decisions. Because it
contains additional information used by the TRILL protocol not
applicable to 802.1D/Q bridges, it is a superset of the corresponding
subtrees defined in the BRIDGE-MIB and Q-BRIDGE-MIB.
5.4 The rbridgeVlan subtree
This subtree describes objects applicable to VLANs configured on the
RBridge.
Rijhsinghani & Zebrose Expires June 6, 2013 [Page 4]
Internet-Draft RBridges: TRILL Base MIB December 3, 2012
5.5 The rbridgeEsadi subtree
This subtree describes objects relevant to RBridges that support the
optional ESADI protocol.
5.6 The rbridgeCounters subtree
This subtree contains statistics maintained by RBridges that can aid
in monitoring and troubleshooting networks connected by them.
5.7 The rbridgeSnooping subtree
This subtree describes objects applicable to RBridges capable of
snooping IPv4 and/or IPv6 Multicast control frames and pruning IP
multicast traffic based on detection of IP multicast routers and
listeners.
5.8 The rbridgeDtree subtree
This subtree contains objects relevant to Distribution Trees computed
by RBridges for the forwarding of multi-destination frames.
5.9 The rbridgeTrill subtree
This subtree contains objects applicable to the TRILL IS-IS protocol,
beyond what is available in ISIS-MIB.
5.10 The Notifications Subtree
The defined notifications are focused on the TRILL protocol
functionality. Notifications are defined for changes in the
Designated RBridge status and the topology.
6. Relationship to Other MIB Modules
The IF-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB, IEEE8021-BRIDGE-
MIB, IEEE8021-Q-BRIDGE-MIB and ISIS-MIB modules all contain objects
relevant to the RBridge MIB. Management objects contained in these
modules are not duplicated here, to reduce overlap to the extent
possible.
The Bridge MIB modules were originally written in the IETF, and
implemented by many vendors. Per [RFC4663], this has recently been
transferred to the IEEE 802.1 group. As vendors may have implemented
either the IETF or IEEE Bridge MIB modules, this RBridge MIB module
is designed to work with either one.
Rijhsinghani & Zebrose Expires June 6, 2013 [Page 5]
Internet-Draft RBridges: TRILL Base MIB December 3, 2012
6.1 Relationship to IF-MIB
The port identification elements MUST be implemented in order to
allow them to be cross referenced. The Interface MIB [RFC2863]
requires that any MIB module which is an adjunct of the Interface MIB
clarify specific areas within the Interface MIB module. These areas
were intentionally left vague in the Interface MIB module to avoid
over-constraining the MIB, thereby precluding management of certain
media types. Section 4 of [RFC2863] enumerates several areas which a
media-specific MIB module must clarify. The implementor is referred
to [RFC2863] in order to understand the general intent of these
areas.
6.2 Relationship to BRIDGE-MIB
The following subtrees in the BRIDGE-MIB [RFC4188] contain
information relevant to RBridges when the corresponding functionality
is implemented.
o dot1dBase
o dot1dTp
o dot1dStatic
6.3 Relationship to P-BRIDGE-MIB
The following subtrees in the P-BRIDGE-MIB [RFC4363] contain
information relevant to RBridges when the corresponding functionality
is implemented.
o dot1dExtBase
o dot1dPriority
o dot1dGarp
o dot1dGmrp
o dot1dTpHCPortTable
o dot1dTpPortOverflowTable
6.4 Relationship to Q-BRIDGE-MIB
The following groups in the Q-BRIDGE-MIB [RFC4363] contain
information relevant to RBridges when the corresponding functionality
is implemented. This functionality is also contained in IEEE8021-Q-
BRIDGE-MIB.
o dot1qBase
o dot1qTp
o dot1qStatic
o dot1qVlan
o dot1vProtocol
Rijhsinghani & Zebrose Expires June 6, 2013 [Page 6]
Internet-Draft RBridges: TRILL Base MIB December 3, 2012
6.5 Relationship to IEEE8021-BRIDGE-MIB
The following subtrees in the IEEE8021-BRIDGE-MIB contain information
relevant to RBridges when the corresponding functionality is
implemented.
o ieee8021BridgeBase
o ieee8021BridgeTp
o ieee8021BridgePriority
o ieee8021BridgeMrp
o ieee8021BridgeMmrp
o ieee8021BridgeInternalLan
o ieee8021BridgeDot1d
6.6 Relationship to IEEE8021-Q-BRIDGE-MIB
The following subtrees in the IEEE8021-Q-BRIDGE-MIB contain
information relevant to RBridges when the corresponding functionality
is implemented.
o ieee8021QBridgeBase
o ieee8021QBridgeTp
o ieee8021QBridgeStatic
o ieee8021QBridgeVlan
o ieee8021QBridgeProtocol
6.7 Relationship to ISIS-MIB
The Management Information Base for Intermediate System to
Intermediate System (IS-IS)[RFC4444] defines a MIB module for the IS-
IS Routing protocol when it is used to construct routing tables for
IP networks. While most of these objects are applicable to the TRILL
layer 2 implementation, note the IS-IS constraints for the current
version of TRILL [RFC6325]:
o The TRILL IS-IS instance uses a single Level 1 IS-IS area.
o The TRILL Level 1 IS-IS area uses the fixed area address zero.
o The TRILL IS-IS instance is not used for IP address advertisement.
o The TRILL IS-IS instance is used for only a single protocol: TRILL.
Accordingly, tables which report IP address reachability and tables
which allow configuration or reporting of multiple IS-IS areas,
multiple IS-IS levels or multiple protocols, will be empty in the
ISIS-MIB module for the current version of TRILL.
Rijhsinghani & Zebrose Expires June 6, 2013 [Page 7]
Internet-Draft RBridges: TRILL Base MIB December 3, 2012
Note also that when more than one instance of the IS-IS protocol is
running on a device, as in the case of a device performing both
RBridge and IS-IS IP router functions, multiple instances of the
ISIS-MIB module can be distinguished by the use of SNMPv3 contexts or
SNMPv1 communities.
6.8 MIB modules required for IMPORTS
The following MIB module IMPORTS objects from SNMPv2-SMI [RFC2578],
SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB [RFC2863],
INET-ADDRESS-MIB[RFC4001], BRIDGE-MIB[RFC4188] and
Q-BRIDGE-MIB[RFC4363]. (The IEEE Bridge MIB modules import similar
TCs.)

8. Security Considerations
This MIB relates to a system which will provide network connectivity
and packet forwarding services. As such, improper manipulation of the
objects represented by this MIB may result in denial of service to a
large number of end-users.
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write and/or read-create. Such
objects may be considered sensitive or vulnerable in some network
environments. The support for SET operations in a non-secure
environment without proper protection can have a negative effect on
network operations. These tables and objects and their
sensitivity/vulnerability are described below.
Rijhsinghani & Zebrose Expires June 6, 2013 [Page 52]
Internet-Draft RBridges: TRILL Base MIB December 3, 2012
The following tables and objects in the RBRIDGE-MIB can be
manipulated to interfere with the operation of RBridges:
o rbridgeBaseUniMultipathEnable affects the ability of the RBridge to
multipath unicast traffic, and rbridgeBaseMultiMultipathEnable
affects the ability of the Rbridge to multipath multi-destination
traffic.
o rbridgeBasePortTable contains a number of objects that may affect
network connectivity. Actions that may be triggered by manipulating
objects in this table include disabling of an RBridge port;
discarding of native packets; disabling learning and others.
o rbridgeEsadiTable contains objects that affect the operation of the
ESADI protocol used for learning, and manipulation of the objects
contained therein can be used to confuse the learning ability of
Rbridges.
o rbridgeDtreePriority can affect computation of distribution trees
within an Rbridge campus, thereby affecting forwarding of multi-
destination traffic.
o rbridgeTrillMinMtuDesired can affect the size of packets being used
to exchange information between RBridges.
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. For example, access to network topology and
Rbridge attributes can reveal information that should not be
available to all users of the network.
SNMP versions prior to SNMPv3 did not include adequate security. Even
if the network itself is secure (for example by using IPsec), 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
Rijhsinghani & Zebrose Expires June 6, 2013 [Page 53]
Internet-Draft RBridges: TRILL Base MIB December 3, 2012
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.
For other RBridge security considerations see [RFC6325].
9. IANA Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER value recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
rbridgeMIB { mib-2 xxx }
Editor's Note (to be removed prior to publication): the IANA is
requested to assign a value for "xxx" under the 'mib-2' subtree and
to record the assignment in the SMI Numbers registry. When the
assignment has been made, the RFC Editor is asked to replace "XXX"
(here and in the MIB module) with the assigned value and to remove
this note.
