Abstract

This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines two MIB modules for managing the capabilities of MAC bridges defined by the IEEE 802.1D-1998 (TM) MAC Bridges and the IEEE 802.1Q-2003 (TM) Virtual LAN (VLAN) standards for bridging between Local Area Network (LAN) segments. One MIB module defines objects for managing the 'Traffic Classes' and 'Enhanced Multicast Filtering' components of IEEE 802.1D-1998 and P802.1t-2001 (TM). The other MIB module defines objects for managing VLANs, as specified in IEEE 802.1Q-2003, P802.1u (TM), and P802.1v (TM).

Provisions are made for support of transparent bridging. Provisions are also made so that these objects apply to bridges connected by subnetworks other than LAN segments.

This memo supplements RFC 4188 and obsoletes RFC 2674.

1 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].

2 Overview

A common device present in many networks is the Bridge. This device is used to connect Local Area Network segments below the network layer. These devices are often known as 'layer 2 switches'.

The transparent method of bridging is defined by IEEE 802.1D-1998 [802.1D]. Managed objects for transparent bridging are defined in the BRIDGE-MIB [BRIDGE-MIB].

The original IEEE 802.1D is augmented by IEEE 802.1Q-2003 [802.1Q] to provide support for 'virtual bridged LANs' where a single bridged physical LAN network may be used to support multiple logical bridged LANs, each of which offers a service approximately the same as that defined by IEEE 802.1D. Such virtual LANs (VLANs) are an integral feature of switched LAN networks. A VLAN can be viewed as a group of end-stations on multiple LAN segments and can communicate as if they were on a single LAN. IEEE 802.1Q defines port-based Virtual LANs where membership is determined by the bridge port on which data frames are received, and port-and-protocol-based Virtual LANs where membership is determined by the bridge port on which frames are received and the protocol identifier of the frame. This memo defines the objects needed for the management of port-based VLANs in bridge entities.

This memo supplements RFC 4188 [BRIDGE-MIB] and obsoletes RFC 2674 [RFC2674].

2.1 Scope

The MIB modules defined in this document include a comprehensive set of managed objects that attempts to match the set defined in IEEE 802.1D and IEEE 802.1Q. However, to be consistent with the spirit of


Page 4

the SNMP Framework, a subjective judgement was made to omit the objects from those standards most 'costly' to implement in an agent and least 'essential' for fault and configuration management. The omissions are described in Section 3 below.

Historical note:

The original BRIDGE-MIB [RFC1493] used the following principles for determining inclusion of an object in the BRIDGE-MIB module:

   (1)   Start with a small set of essential objects and add only as
         further objects are needed.

   (2)   Require that objects be essential for either fault or
         configuration management.

   (3)   Consider evidence of current use and/or utility.

   (4)   Limit the total number of objects.

   (5)   Exclude objects that are simply derivable from others in this
         or other MIBs.

   (6)   Avoid causing critical sections to be heavily instrumented.
         The guideline that was followed is one counter per critical
         section per layer.

3 Structure of MIBs

This document defines objects that supplement those in the BRIDGE-MIB module [BRIDGE-MIB]. Section 3.4.3 of the present document contains some recommendations regarding usage of objects in the BRIDGE-MIB by devices implementing the enhancements defined here.

An extended bridge MIB module P-BRIDGE-MIB defines managed objects for the traffic class and multicast filtering enhancements defined by IEEE 802.1D-1998 [802.1D], including the Restricted Group Registration control defined by IEEE P802.1t [802.1t].

A virtual bridge MIB module Q-BRIDGE-MIB defines managed objects for the Virtual LAN bridging enhancements defined by IEEE 802.1Q-2003 [802.1Q], including the Restricted VLAN Registration control, defined by IEEE P802.1u [802.1u], and the VLAN Classification by Protocol and Port enhancement, defined by IEEE P802.1v [802.1v].

3.1 Structure of Extended Bridge MIB Module

Objects in this MIB are arranged into subtrees. Each subtree is organized as a set of related objects. The overall structure and assignment of objects to their subtrees is shown below.

3.1.1 Relationship to IEEE 802.1D-1998 Manageable Objects

This section contains a cross-reference to the objects defined in IEEE 802.1D-1998 [802.1D]. It also details those objects that are not considered necessary in this MIB module.

Some objects defined by IEEE 802.1D-1998 have been included in the virtual bridge MIB module rather than this one: entries in dot1qTpGroupTable, dot1qForwardAllTable, and
dot1qForwardUnregisteredTable are required for virtual bridged LANs with additional indexing (e.g., per-VLAN, per-Filtering-Database (per-FDB)) and so are not defined here. Instead, devices that do not implement virtual bridged LANs but do implement the Extended Forwarding Services defined by IEEE 802.1D (i.e., dynamic learning of multicast group addresses and group service requirements in the filtering database) should implement these tables with a fixed value for dot1qFdbId (the value 1 is recommended) or dot1qVlanIndex (the value 1 is recommended). Devices that support Extended Filtering Services should support dot1qTpGroupTable, dot1qForwardAllTable, and dot1qForwardUnregisteredTable.

3.1.2 Relationship to IEEE 802.1Q Manageable Objects

This section contains section number cross-references to manageable objects defined in IEEE 802.1Q-2003 [802.1Q]. These objects have been included in this MIB as they provide a natural fit with the IEEE 802.1D objects with which they are co-located.

3.1.3 The dot1dExtBase Subtree

This subtree contains the objects that are applicable to all bridges implementing the traffic class and multicast filtering features of IEEE 802.1D-1998 [802.1D]. It includes per-device configuration of Generic Attribute Registration Protocol (GARP) and GARP Multicast Registration Protocol (GMRP) protocols.

3.1.4 The dot1dPriority Subtree

This subtree contains the objects for configuring and reporting status of priority-based queuing mechanisms in a bridge. This includes per-port user_priority treatment, mapping of user_priority in frames into internal traffic classes, and outbound user_priority and access_priority.

3.1.5 The dot1dGarp Subtree

This subtree contains the objects for configuring and reporting on operation of the Generic Attribute Registration Protocol (GARP).

3.1.6 The dot1dGmrp Subtree

This subtree contains the objects for configuring and reporting on operation of the GARP Multicast Registration Protocol (GMRP).

3.1.7 The dot1dTpHCPortTable

This table extends the dot1dTp subtree from the BRIDGE-MIB [BRIDGE-MIB] and contains the objects for reporting port-bridging statistics for high-capacity network interfaces.

3.1.8 The dot1dTpPortOverflowTable

This table extends the dot1dTp subtree from the BRIDGE-MIB [BRIDGE-MIB] and contains the objects for reporting the upper bits of port-bridging statistics for high-capacity network interfaces for when 32-bit counters are inadequate.

3.2 Structure of Virtual Bridge MIB module

Objects in this MIB are arranged into subtrees. Each subtree is organized as a set of related objects. The overall structure and assignment of objects to their subtrees is shown below. Some manageable objects defined in the BRIDGE-MIB [BRIDGE-MIB] need to be indexed differently when they are used in a VLAN bridging environment: these objects are, therefore, effectively duplicated by new objects with different indexing, which are defined in the Virtual Bridge MIB.

3.2.1 Relationship to IEEE 802.1Q Manageable Objects

This section contains section-number cross-references to manageable objects defined in clause 12 of IEEE 802.1Q-2003 [802.1Q]. It also details those objects that are not considered necessary in this MIB module.

Note: Unlike IEEE 802.1D-1998, IEEE 802.1Q-2003 [802.1Q] did not define exact syntax for a set of managed objects. The following cross-references indicate the section numbering of the descriptions of management operations from clause 12 in the latter document.

3.2.2 The dot1qBase Subtree

This subtree contains the objects that are applicable to all bridges implementing IEEE 802.1Q virtual LANs.

3.2.3 The dot1qTp Subtree

This subtree contains objects that control the operation and report the status of transparent bridging. This includes management of the dynamic Filtering Databases for both unicast and multicast forwarding. This subtree will be implemented by all bridges that perform destination-address filtering.

3.2.4 The dot1qStatic Subtree

This subtree contains objects that control static configuration information for transparent bridging. This includes management of the static entries in the Filtering Databases for both unicast and multicast forwarding.

3.2.5 The dot1qVlan Subtree

This subtree contains objects that control configuration and report status of the Virtual LANs known to a bridge. This includes management of the statically configured VLANs as well as reporting VLANs discovered by other means (e.g., GARP VLAN Registration Protocol (GVRP)). It also controls configuration and reports status of per-port objects relating to VLANs and reports traffic statistics. It also provides for management of the VLAN Learning Constraints.

3.3 Textual Conventions

Various Working Groups have defined standards-track MIB documents (for example, [RFC2613] and [RFC3318]), that contain objects and Textual Conventions to represent a Virtual Local Area Network Identifier (VLAN-ID) [802.1Q]. New definitions are showing up in various documents (for example, [RFC4323] and [RFC4149]). Unfortunately, the result is a set of different definitions for the same piece of management information. This may lead to confusion and unnecessary complexity. In order to address this situation, three new textual conventions are defined in the Q-BRIDGE-MIB, called VlanIdOrAny, VlanIdOrNone, and VlanIdOrAnyOrNone. These new textual conventions should be (re)used in MIB modules so that they all represent a VLAN-ID in the same way.


Page 13

These textual conventions provide a means to specify MIB objects that refer to a specific VLAN, to any VLAN, or to no VLAN. For an example of how these textual conventions might be used, consider a MIB object, with SYNTAX of VlanIdOrAnyOrNone, that specifies the VLAN on which to accept incoming packets of a particular protocol. Such an object would allow the device to be configured to accept packets of this protocol received with a specific 802.1q tag value, with any 802.1q tag value, or with no 802.1q tag. Note that a MIB object that is defined using one of these textual conventions should clarify the meaning of 'any VLAN' and/or 'no VLAN' in its DESCRIPTION clause.

3.4 Relationship to Other MIBs

As described above, some IEEE 802.1D management objects have not been included in this MIB because they overlap with objects in other MIBs applicable to a bridge implementing this MIB module.

3.4.1 Relationship to the SNMPv2-MIB

The SNMPv2-MIB [RFC3418] defines objects that are generally applicable to managed devices. These objects apply to the device as a whole, irrespective of whether bridging is the device's sole functionality or only a subset of the device's functionality.

Full support for the 802.1D management objects requires that the SNMPv2-MIB objects sysDescr and sysUpTime be implemented. Note that compliance to the current SNMPv2-MIB module requires additional objects and notifications to be implemented as specified in RFC 3418 [RFC3418].

3.4.2 Relationship to the IF-MIB

The IF-MIB, [RFC2863], requires that any MIB that is an adjunct of the IF-MIB clarify specific areas within the IF-MIB. These areas were intentionally left vague in the IF-MIB in order to avoid over- constraining the MIB, thereby precluding management of certain media-types.

The IF-MIB enumerates several areas that a media-specific MIB must clarify. Each of these areas is addressed in a following subsection. The implementor is referred to the IF-MIB in order to understand the general intent of these areas.

The IF-MIB [RFC2863] defines managed objects for managing network interfaces. A network interface is considered attached to a 'subnetwork'. (Note that this term is not to be confused with 'subnet', which refers to an addressing partitioning scheme used in the Internet suite of protocols.) The term 'segment' is used in this


Page 14

memo to refer to such a subnetwork, whether it be an Ethernet segment, a 'ring', a WAN link, or even an X.25 virtual circuit.

Full support for the 802.1D management objects requires that the IF-MIB objects ifIndex, ifType, ifDescr, ifPhysAddress, and ifLastChange are implemented. Note that compliance to the current IF-MIB module requires additional objects and notifications to be implemented as specified in RFC 2863 [RFC2863].

Implicit in this Extended Bridge MIB is the notion of ports on a bridge. Each of these ports is associated with one interface of the 'interfaces' subtree (one row in ifTable), and, in most situations, each port is associated with a different interface. However, there are situations in which multiple ports are associated with the same interface. An example of such a situation would be several ports each corresponding one-to-one with several X.25 virtual circuits but all on the same interface.

Each port is uniquely identified by a port number. A port number has no mandatory relationship to an interface number, but in the simple case a port number will have the same value as the corresponding interface's interface number. Port numbers are in the range (1..dot1dBaseNumPorts).

Some entities perform other functionality as well as bridging through the sending and receiving of data on their interfaces. In such situations, only a subset of the data sent/received on an interface is within the domain of the entity's bridging functionality. This subset is considered delineated according to a set of protocols, with some protocols being bridged, and other protocols not being bridged. For example, in an entity that exclusively performed bridging, all protocols would be considered bridged, whereas in an entity that performed IP routing on IP datagrams and only bridged other protocols, only the non-IP data would be considered bridged.

Thus, this Extended Bridge MIB (and in particular, its counters) is applicable only to that subset of the data on an entity's interfaces that is sent/received for a protocol being bridged. All such data is sent/received via the ports of the bridge.

3.4.2.1 Layering Model

This memo assumes the interpretation of the Interfaces Subtree to be in accordance with the IF-MIB [RFC2863], which states that the interfaces table (ifTable) contains information on the managed resource's interfaces and that each sub-layer below the internetwork layer of a network interface is considered an interface.


Page 15

This document does not make any assumption that within an entity, VLANs that are instantiated as an entry in dot1qVlanCurrentTable by either management configuration through dot1qVlanStaticTable or by dynamic means (e.g., through GVRP) are also represented by an entry in ifTable.

Where an entity contains higher-layer protocol entities (e.g., IP-layer interfaces that transmit and receive traffic to/from a VLAN), these should be represented in the ifTable as interfaces of type propVirtual(53). Protocol-specific types such as l3ipxvlan(137) should not be used here, since there is no implication that the bridge will perform any protocol filtering before delivering up to these virtual interfaces.

3.4.2.2 ifStackTable

In addition, the IF-MIB [RFC2863] defines a table 'ifStackTable' for describing the relationship between logical interfaces within an entity. It is anticipated that implementors will use this table to describe the binding of (for example) IP interfaces to physical ports, although the presence of VLANs makes the representation less than perfect for showing connectivity. The ifStackTable cannot represent the full capability of the IEEE 802.1Q VLAN bridging standard, since that makes a distinction between VLAN bindings on 'ingress' to and 'egress' from a port: these relationships may or may not be symmetrical whereas Interface MIB Evolution assumes a symmetrical binding for transmit and receive. This makes it necessary to define other manageable objects for configuring which ports are members of which VLANs.

3.4.2.3 ifRcvAddressTable

This table contains all MAC addresses, unicast, multicast, and broadcast, for which an interface will receive packets and forward them up to a higher-layer entity for local consumption. Note that this does not include addresses for data-link layer control protocols such as Spanning-Tree, GMRP, or GVRP. The format of the address, contained in ifRcvAddressAddress, is the same as for ifPhysAddress.

This table does not include unicast or multicast addresses that are accepted for possible forwarding out some other port. This table is explicitly not intended to provide a bridge address filtering mechanism.


Page 16

3.4.3 Relationship to the BRIDGE-MIB

This section defines how objects in the BRIDGE-MIB module [BRIDGE-MIB] should be represented for devices that implement the extensions: some of the old objects are less useful in such devices but must still be implemented for reasons of backwards compatibility.

3.4.3.1 The dot1dBase Subtree

This subtree contains objects that are applicable to all types of bridges. Interpretation of this subtree is unchanged.

3.4.3.2 The dot1dStp Subtree

This subtree contains the objects that denote the bridge's state with respect to the Spanning Tree Protocol. Interpretation of this subtree is unchanged.

3.4.3.3 The dot1dTp Subtree

This subtree contains objects that describe the entity's state with respect to transparent bridging.

In a device operating with a single Filtering Database,
interpretation of this subtree is unchanged.

In a device supporting multiple Filtering Databases, this subtree is interpreted as follows:

dot1dTpLearnedEntryDiscards

The number of times that *any* of the FDBs became full.

dot1dTpAgingTime

This applies to all Filtering Databases.

dot1dTpFdbTable

Report MAC addresses learned on each port, regardless of which Filtering Database they have been learned in. If an address has been learned in multiple databases on a single port, report it only once. If an address has been learned in multiple databases on more than one port, report the entry on any one of the valid ports.


Page 17

dot1dTpPortTable

This table is port-based and is not affected by multiple Filtering Databases or multiple VLANs. The counters should include frames received or transmitted for all VLANs. Note that equivalent 64-bit port statistics counters, as well as other objects to represent the upper 32 bits of these counters, are defined in this document for high-capacity network interfaces. These have conformance statements to indicate for which speeds of interface they are required.

3.4.3.4 The dot1dStatic Subtree

This optional subtree contains objects that describe the
configuration of destination-address filtering.

In a device operating with a single Filtering Database,
interpretation of this subtree is unchanged.

In a device supporting multiple Filtering Databases, this subtree is interpreted as follows:

dot1dStaticTable

Entries read from this table include all static entries from all of the Filtering Databases. Entries for the same MAC address and receive port in more than one Filtering Database must appear only once, since these are the indices of this table. This table should be implemented as read-only in devices that support multiple Forwarding Databases. Instead, write access should be provided through dot1qStaticUnicastTable and
dot1qStaticMulticastTable, as defined in this document.

3.4.3.5 Additions to the BRIDGE-MIB

To supplement the BRIDGE-MIB [BRIDGE-MIB], this module contains:

   (1)   support for multiple traffic classes and dynamic multicast
         filtering as per IEEE 802.1D-1998 [802.1D].

   (2)   support for bridged Virtual LANs as per IEEE 802.1Q-2003
         [802.1Q].

   (3)   support for 64-bit versions of BRIDGE-MIB [BRIDGE-MIB] port
         counters.

    DESCRIPTION
        "Each octet within this value specifies a set of eight
        ports, with the first octet specifying ports 1 through
        8, the second octet specifying ports 9 through 16, etc.
        Within each octet, the most significant bit represents
        the lowest numbered port, and the least significant bit
        represents the highest numbered port.  Thus, each port
        of the bridge is represented by a single bit within the
        value of this object.  If that bit has a value of '1',
        then that port is included in the set of ports; the port
        is not included if its bit has a value of '0'."

        4094 inclusive, it represents an IEEE 802.1Q VLAN-ID with
        global scope within a given bridged domain (see VlanId
        textual convention).  If the value is greater than 4095,

then it represents a VLAN with scope local to the
particular agent, i.e., one without a global VLAN-ID assigned to it. Such VLANs are outside the scope of IEEE 802.1Q, but it is convenient to be able to manage them in the same way using this MIB."
