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
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.

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.
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
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.
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.
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.
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.

including Restricted Vlan Registration defined by
IEEE 802.1u-2001 and Vlan Classification defined by
IEEE 802.1v-2001.
Copyright (C) The Internet Society (2006). This version of
this MIB module is part of RFC 4363; See the RFC itself for
full legal notices."
REVISION "200601090000Z"
DESCRIPTION
"Added Vlan TEXTUAL-CONVENTIONs,
dot1qPortRestrictedVlanRegistration, dot1vProtocol subtree,
qBridgeClassificationDeviceGroup, qBridgePortGroup2,
qBridgeClassificationPortGroup, and qBridgeCompliance2.
Clarified dot1qForwardAllStaticPorts,

PortList ::= TEXTUAL-CONVENTION
STATUS current
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'."
SYNTAX OCTET STRING
VlanIndex ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"A value used to index per-VLAN tables: values of 0 and
4095 are not permitted. If the value is between 1 and
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."

DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"The VLAN-ID that uniquely identifies a specific VLAN,
or any VLAN. The special value of 4095 is used to
indicate a wildcard, i.e., any VLAN. This can be used
in any situation where an object or table entry must
refer either to a specific VLAN or to any VLAN.
Note that a MIB object that is defined using this
TEXTUAL-CONVENTION should clarify the meaning of
'any VLAN' (i.e., the special value 4095)."

VlanIdOrNone ::= TEXTUAL-CONVENTION
DISPLAY-HINT "d"
STATUS current
DESCRIPTION
"The VLAN-ID that uniquely identifies a specific VLAN,
or no VLAN. The special value of zero is used to
indicate that no VLAN-ID is present or used. This can
be used in any situation where an object or a table entry
must refer either to a specific VLAN, or to no VLAN.
Note that a MIB object that is defined using this
TEXTUAL-CONVENTION should clarify the meaning of
'no VLAN' (i.e., the special value 0)."

6. Acknowledgements
Much of the groundwork for this document was performed by the IEEE
802.1 working group during the definition of the IEEE 802.1D updates
[802.1D] and IEEE 802.1Q [802.1Q].
The authors wish to thank the members of the Bridge Working Group,
and David Harrington, Anders SW Christensen, Andrew Smith, Paul
Langille, Anil Rijhsinghani, and Keith McCloghrie in particular for
their comments and suggestions, which improved this effort.
Editing for the final version was done by David Levi.
The new textual conventions related to VLAN-IDs were produced as a
result of a review of the use of VLAN-ID in several MIB modules.
Further investigation found that VLAN-ID objects were defined in a
few other MIB modules. The editor would like to thank all who
contributed to the discussion that resulted in these new textual
conventions. Specifically, Bert Wijnen, Les Bell, Andrew Smith, Mike
Heard, Randy Presuhn, Dan Romascanu, Eduardo Cardona, Tom Petch,
Juergen Schoenwaelder, Richard Woundy, Tony Jeffree, and William
Murwin. We also received input and feedback from IEEE confirming
that the values 0 and 4095 are not used for identifying a specific
VLAN-ID and so can be used to represent none or a wildcard (see
Appendix A).
7. Security Considerations
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.
The following tables and objects in the P-BRIDGE-MIB can be
manipulated to interfere with the operation of priority classes.
This could, for example, be used to force a reinitialization of state
machines, thus causing network instability. Another possibility
would be for an attacker to override established policy on port
priorities, thus giving a user (or an attacker) unauthorized
preferential treatment.
dot1dTrafficClassesEnabled
dot1dGmrpStatus
dot1dPortPriorityTable
dot1dUserPriorityRegenTable
dot1dTrafficClassTable
dot1dPortGarpTable
dot1dPortGmrpTable
The following tables and objects in the Q-BRIDGE-MIB could be
manipulated to interfere with the operation of virtual LANs. This
could, for example, be used to force a reinitialization of state
machines to cause network instability, or changing the forwarding and
filtering policies.
dot1qGvrpStatus
dot1qForwardAllTable
dot1qStaticUnicastTable
dot1qStaticMulticastTable
dot1qVlanStaticTable
dot1qPortVlanTable
dot1qLearningConstraintsTable
dot1vProtocolGroupTable
dot1vProtocolPortTable
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. These are the tables and objects and their
sensitivity/vulnerability.
The objects dot1dDeviceCapabilities and dot1dPortCapabilitiesTable in
the P-BRIDGE-MIB could be used by an attacker to determine which
attacks might be useful to attempt against a given device.
The following read-only tables and objects in the Q-BRIDGE-MIB could
be used by an attacker to determine which attacks might be useful to
attempt against a given device, could be used by an attacker to
detect whether their attacks are being blocked or filtered, or could
be used to understand the logical topology 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),
even then, 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
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.

Subject: RE: VLAn ID
Bert et al -
We have concluded that the use of 4095 as a wildcard is acceptable
to 802.1, and we will make any necessary changes to 802.1Q in due
course to relax the current stated restriction. However, we need
to know whether that is all that needs to be done to 802.1Q - i.e.,
is there any need to change our definitions of the managed objects
in the document (Clause 12) to reflect the interpretation of 4095
as a wildcard, or is this simply an issue for the SNMP machinery
to handle?
Regards,
Tony
