1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for modeling
Generalized Multiprotocol Label Switching (GMPLS) [RFC3945] based
traffic engineering. The tables and objects defined in this document
extend those defined in the equivalent document for MPLS traffic
engineering [RFC3812], and management of GMPLS traffic engineering is
built on management of MPLS traffic engineering.
The MIB modules in this document should be used in conjunction with
the companion document [GMPLSLSRMIB] for GMPLS based traffic
engineering configuration and management.
Comments should be made direct to the CCAMP mailing list at
ccamp@ops.ietf.org.

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 BCP 14, RFC 2119,
reference [RFC2119].
1.1. Migration Strategy
MPLS-TE LSPs may be modeled and managed using the MPLS-TE-STD-MIB
module [RFC3812].
LSRs may be migrated to model and manage their TE LSPs using the MIB
modules in this document in order to migrate the LSRs to GMPLS
support, or to take advandtage of additional MIB objects defined in
these MIB modules that are applicable to MPLS-TE.
The GMPLS TE MIB module (GMPLS-TE-STD-MIB) defined in this document
extends the MPLS-TE-STD-MIB module [RFC3812] through a series of
augmentations and sparse augmentations of the MIB tables. The only
additions are for support of GMPLS or to support the increased
complexity of MPLS and GMPLS systems.
In order to migrate from MPLS-TE-STD-MIB support to GMPLS-TE-STD-MIB
support an implementation needs only to add support for the
additional tables and objects defined in GMPLS-TE-STD-MIB. The
gmplsTunnelLSPEncoding may be set to tunnelLspNotGmpls to allow an
MPLS-TE LSP tunnel to benefit from the additional objects and tables
of GMPLS-LSR-STD-MIB without supporting the GMPLS protocols.
The companion document for modeling and managing GMPLS based LSRs
[GMPLSLSRMIB] extends the MPLS-LSR-STD-MIB module [RFC3813] with the
same intentions.
Textual conventions are defined in [RFC3811] and [GMPLSTCMIB].
2. Terminology
This document uses terminology from the MPLS architecture document
[RFC3031], from the GMPLS architecture document [RFC3945], and from
the MPLS Traffic Engineering MIB [RFC3812]. Some frequently used
terms are described next.
An explicitly routed LSP (ERLSP) is referred to as a GMPLS tunnel. It
consists of in-segment(s) and/or out-segment(s) at the egress/ingress
LSRs, each segment being associated with one GMPLS enabled interface.
These are also referred to as tunnel segments.
Additionally, at an intermediate LSR, we model a connection as
consisting of one or more in-segments and/or one or more
out-segments. The binding or interconnection between in-segments and
Nadeau and Farrel (Editors) [Page 3]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
out-segments in performed using a cross-connect.
These segment and cross-connect objects are defined in the MPLS Label
Switch Router MIB (MPLS-LSR-STD-MIB) [RFC3813], but see also the
GMPLS Label Switch Router MIB (GMPLS-LSR-STD-MIB) [GMPLSLSRMIB] for
the GMPLS-specific extensions to these objects.
3. The SNMP 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].
4. Outline
Support for GMPLS traffic-engineered tunnels requires the following
configuration.
- Setting up tunnels with appropriate MPLS configuration parameters
using [RFC3812].
- Extending the tunnels with GMPLS configuration parameters.
- Configuring tunnel loose and strict source routed hops.
These actions may need to be accompanied with corresponding actions
using [RFC3813] and [GMPLSLSRMIB] to establish and configure tunnel
segments, if this is done manually. Also, the in-segment and
out-segment performance tables, mplsInSegmentPerfTable and
mplsOutSegmentPerfTable [RFC3813], should be used to determine
performance of the tunnels and tunnel segments although it should be
noted that those tables may not be appropriate for measuring
performance on some types of GMPLS links.
4.1. Summary of GMPLS Traffic Engineering MIB Module
The following tables contain MIB objects for performing the actions
listed above when they cannot be performed solely using MIB objects
defined in MPLS-TE-STD-MIB [RFC3812].
- Tunnel Table (gmplsTunnelTable) for providing GMPLS-specific
tunnel configuration parameters.
Nadeau and Farrel (Editors) [Page 4]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
- Tunnel specified, actual, and computed hop tables
(gmplsTunnelHopTable, gmplsTunnelARHopTable, and
gmplsTunnelCHopTable) for providing additional configuration of
strict and loose source routed tunnel hops.
- Performance and error reporting tables (gmplsTunnelReversePerfTable
and gmplsTunnelErrorTable).
These tables are described in the subsequent sections.
Additionally, the GMPLS-TE-STD-MIB module contains a new
notification.
- The GMPLS Tunnel Down Notification (gmplsTunnelDown) should be used
for all GMPLS tunnels in place of the mplsTunnelDown notification
defined in [RFC3812]. An implementation must not issue both the
gmplsTunnelDown and the mplsTunnelDown notifications for the same
event. As well as indicating that a tunnel has transitioned to
operational down state, this new notification indicates the cause
of the failure.
5. Brief Description of GMPLS TE MIB Objects
The objects described in this section support the functionality
described in [RFC3473] and [RFC3472] for GMPLS tunnels. The tables
support both manually configured and signaled tunnels.
5.1. gmplsTunnelTable
The gmplsTunnelTable extends the MPLS traffic engineering MIB module
(MPLS-TE-STD-MIB [RFC3812]) to allow GMPLS tunnels to be created
between an LSR and a remote endpoint, and existing GMPLS tunnels to
be reconfigured or removed.
Note that we only support point-to-point tunnel segments, although
multi-point-to-point and point-to-multi-point connections are
supported by an LSR acting as a cross-connect.
Each tunnel can thus have one out-segment originating at an LSR
and/or one in-segment terminating at that LSR.
Three objects within this table utilize enumerations in order to map
to enumerations that are used in GMPLS signaling. In order to protect
the GMPLS-TE-STD-MIB module from changes (in particular, extensions)
to the range of enumerations supported by the signaling protocols,
these MIB objects use Textual Conventions with values maintained by
IANA. For further details, see the IANA Considerations section of
this document.
Nadeau and Farrel (Editors) [Page 5]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
5.2. gmplsTunnelHopTable
The gmplsTunnelHopTable is used to indicate additional parameters for
the hops, strict or loose, of a GMPLS tunnel defined in
gmplsTunnelTable, when it is established using signaling. Multiple
tunnels may share hops by pointing to the same entry in this table.
5.3. gmplsTunnelARHopTable
The gmplsTunnelARHopTable is used to indicate the actual hops
traversed by a tunnel as reported by the signaling protocol after the
tunnel is setup. The support of this table is optional since not all
GMPLS signaling protocols support this feature.
5.4. gmplsTunnelCHopTable
The gmplsTunnelCHopTable lists the actual hops computed by a
constraint-based routing algorithm based on the gmplsTunnelHopTable.
The support of this table is optional since not all implementations
support computation of hop lists using a constraint-based routing
protocol.
5.5. gmplsTunnelErrorTable
The gmplsTunnelErrorTable provides access to information about the
last error that occurred on each tunnel known about by the MIB. It
indicates the nature of the error, when and how it was reported and
can give recovery advice through an admin string.
5.6. gmplsTunnelReversePerfTable
gmplsTunnelReversePerfTable provides additional counters to measure
the performance of bidirectional GMPLS tunnels in which packets are
visible. It supplements the counters in mplsTunnelPerfTable and
augments gmplsTunnelTable.
Note that not all counters may be appropriate or available for some
types of tunnel.
5.7. Use of 32-bit and 64-bit Counters
64-bit counters are provided in the GMPLS-TE-STD-MIB module for
high-speed interfaces where the use of 32-bit counters might be
impractical. The requirements on the use of 32-bit and 64-bit
counters (copied verbatim from [RFC2863]) are as follows:
For interfaces that operate at 20,000,000 (20 million) bits per
second or less, 32-bit byte and packet counters MUST be supported.
For interfaces that operate faster than 20,000,000 bits/second, and
Nadeau and Farrel (Editors) [Page 6]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
slower than 650,000,000 bits/second, 32-bit packet counters MUST be
supported and 64-bit octet counters MUST be supported. For
interfaces that operate at 650,000,000 bits/second or faster, 64-bit
packet counters AND 64-bit octet counters MUST be supported.
6. Cross-referencing to the gmplsLabelTable
The gmplsLabelTable is found in the GMPLS-LABEL-STD-MIB module in
[GMPLSLSRMIB] and provides a way to model labels in a GMPLS system
where labels might not be simple 32 bit integers.
The hop tables in this document (gmplsHopTable, gmplsCHopTable and
gmplsARHopTable) and the segment tables in the [RFC3813]
(mplsInSegmentTable and mplsOutSegmentTable) contain objects with
syntax MplsLabel.
MplsLabel (defined in [RFC3811]) is a 32-bit integer that is capable
of representing any MPLS label and most GMPLS labels. However, some
GMPLS labels are larger than 32 bits and may be of arbitrary length.
Further, some labels that may be safely encoded in 32 bits are
constructed from multiple sub-fields. Additionally, some GMPLS
technologies support the concatenation of individual labels to
represent a data flow carried as multiple sub-flows.
These GMPLS cases require that something other than a simple 32-bit
integer is made available to represent the labels. This is achieved
through the gmplsLabelTable contained in the GMPLS-LABEL-STD-MIB
[GMPLSLSRMIB].
The tables in this document and [RFC3813] that include objects with
syntax MplsLabel also include companion objects that are row
pointers. If the row pointer is set to zeroDotZero (0.0) then object
of syntax MplsLabel contains the label encoded as a 32-bit integer.
But otherwise the row pointer indicates a row in another MIB table
that includes the label. In these cases, the row pointer may indicate
a row in the gmplsLabelTable.
This provides both a good way to support legacy systems that
implement the MPLS-TE-STD-MIB [RFC3812], and a significant
simplification in GMPLS systems that are limited to a single, simple
label type.
Note that gmplsLabelTable supports concatenated labels through the
use of a label sub-index (gmplsLabelSubindex).
7. Example of GMPLS Tunnel Setup
This section contains an example of which MIB objects should be
modified to create a GMPLS tunnel. This example shows a best effort,
Nadeau and Farrel (Editors) [Page 7]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
loosely routed, bidirectional traffic engineered tunnel, which spans
two hops of a simple network, uses Generalized Label requests with
Lambda encoding, has label recording and shared link layer
protection. Note that these objects should be created on the
"head-end" LSR.
First in the mplsTunnelTable:
{
mplsTunnelIndex = 1,
mplsTunnelInstance = 1,
mplsTunnelIngressLSRId = 192.168.100.1,
mplsTunnelEgressLSRId = 192.168.200.1,
mplsTunnelName = "My first tunnel",
mplsTunnelDescr = "Here to there and back again",
mplsTunnelIsIf = true (1),
mplsTunnelXCPointer = mplsXCIndex.3.0.0.12,
mplsTunnelSignallingProto = none (1),
mplsTunnelSetupPrio = 0,
mplsTunnelHoldingPrio = 0,
mplsTunnelSessionAttributes = recordRoute (4),
mplsTunnelOwner = snmp (2),
mplsTunnelLocalProtectInUse = false (2),
mplsTunnelResourcePointer = mplsTunnelResourceIndex.6,
mplsTunnelInstancePriority = 1,
mplsTunnelHopTableIndex = 1,
mplsTunnelPrimaryInstance = 0,
mplsTunnelIncludeAnyAffinity = 0,
mplsTunnelIncludeAllAffinity = 0,
mplsTunnelExcludeAnyAffinity = 0,
mplsTunnelPathInUse = 1,
mplsTunnelRole = head(1),
mplsTunnelRowStatus = createAndWait (5),
}
In gmplsTunnelTable(1,1,192.168.100.1,192.168.200.1):
{
gmplsTunnelUnnumIf = true (1),
gmplsTunnelAttributes = labelRecordingRequired (1),
gmplsTunnelLSPEncoding = tunnelLspLambda,
gmplsTunnelSwitchingType = lsc,
gmplsTunnelLinkProtection = shared (2),
gmplsTunnelGPid = lambda,
gmplsTunnelSecondary = false (2),
gmplsTunnelDirection = bidirectional (1)
gmplsTunnelPathComp = explicit(2),
gmplsTunnelRequestedUpstreamNotifyRecipientType = ipv4(1),
gmplsTunnelRequestedUpstreamNotifyRecipient = 'C0A86401'H,
gmplsTunnelAdminStatusFlags = 0,
Nadeau and Farrel (Editors) [Page 8]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
gmplsTunnelExtraParamsPtr = 0.0
}
Entries in the mplsTunnelResourceTable, mplsTunnelHopTable and
gmplsTunnelHopTable are created and activated at this time.
In mplsTunnelResourceTable:
{
mplsTunnelResourceIndex = 6,
mplsTunnelResourceMaxRate = 0,
mplsTunnelResourceMeanRate = 0,
mplsTunnelResourceMaxBurstSize = 0,
mplsTunnelResourceRowStatus = createAndGo (4)
}
The next two instances of mplsTunnelHopEntry are used to denote the
hops this tunnel will take across the network.
The following denotes the beginning of the network, or the first hop.
We have used the fictitious LSR identified by "192.168.100.1" as our
example head-end router.
In mplsTunnelHopTable:
{
mplsTunnelHopListIndex = 1,
mplsTunnelPathOptionIndex = 1,
mplsTunnelHopIndex = 1,
mplsTunnelHopAddrType = ipV4 (1),
mplsTunnelHopIpv4Addr = 192.168.100.1,
mplsTunnelHopIpv4PrefixLen = 9,
mplsTunnelHopType = strict (1),
mplsTunnelHopRowStatus = createAndWait (5),
}
The following denotes the end of the network, or the last hop in our
example. We have used the fictitious LSR identified by
"192.168.200.1" as our end router.
In mplsTunnelHopTable:
{
mplsTunnelHopListIndex = 1,
mplsTunnelPathOptionIndex = 1,
mplsTunnelHopIndex = 2,
mplsTunnelHopAddrType = ipV4 (1),
mplsTunnelHopIpv4Addr = 192.168.100.1,
mplsTunnelHopIpv4PrefixLen = 9,
mplsTunnelHopType = loose (2),
mplsTunnelHopRowStatus = createAndGo (4)
}
Nadeau and Farrel (Editors) [Page 9]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
Now an associated entry in the gmplsTunnelHopTable is created to
provide additional GMPLS hop configuration indicating that the first
hop is an unnumbered link using explicit forward and reverse labels.
An entry in the gmplsLabelTable is created first to include the
explicit label.
In gmplsLabelTable:
{
gmplsLabelInterface = 2,
gmplsLabelIndex = 1,
gmplsLabelSubindex = 0,
gmplsLabelType = gmplsFreeformLabel(3),
gmplsLabelFreeform = 0xFEDCBA9876543210
gmplsLabelRowStatus = createAndGo(4)
}
In gmplsTunnelHopTable(1,1,1):
{
gmplsTunnelHopLabelStatuses = forwardPresent(0)
+reversePresent(1),
gmplsTunnelHopExplicitForwardLabelPtr = gmplsLabelTable (2, 1, 0)
gmplsTunnelHopExplicitReverseLabelPtr = gmplsLabelTable (2, 1, 0)
}
The first hop is now activated:
In mplsTunnelHopTable(1,1,1):
{
mplsTunnelHopRowStatus = active (1)
}
No gmplsTunnelHopEntry is created for the second hop as it contains
no special GMPLS features.
Finally the mplsTunnelEntry is activated:
In mplsTunnelTable(1,1,192.168.100.1,192.168.200.1)
{
mplsTunnelRowStatus = active(1)
}

occur more rapidly, the implementation may simply fail to emit
some notifications during that period, or may queue them until

9. Security Considerations
It is clear that the MIB modules described in this document in
association with the MPLS-TE-STD-MIB [RFC3812] are potentially useful
for monitoring of MPLS and GMPLS tunnels. These MIB modules can also
be used for configuration of certain objects, and anything that can
be configured can be incorrectly configured, with potentially
disastrous results.
There are a number of management objects defined in these MIB modules
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 are the tables and objects and their
sensitivity/vulnerability:
o the gmplsTunnelTable and gmplsTunnelHopTable collectively contain
objects to provision GMPLS tunnels interfaces at their ingress
LSRs. Unauthorized write access to objects in these tables, could
result in disruption of traffic on the network. This is especially
true if a tunnel has already been established.
Some of the readable objects in these MIB modules (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:
o the gmplsTunnelTable, gmplsTunnelHopTable, gmplsTunnelARHopTable,
gmplsTunnelCHopTable, gmplsTunnelReversePerfTable,
gmplsTunnelErrorTable collectively show the tunnel network
topology and status. If an Administrator does not want to reveal
this information, then these tables should be considered
sensitive/vulnerable.
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
these MIB modules.
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).
Nadeau and Farrel (Editors) [Page 48]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
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.
10. Acknowledgments
This document is a product of the CCAMP Working Group.
This document extends [RFC3812]. The authors would like to express
their gratitude to all those who worked on that earlier MIB document.
Thanks also to Tony Zinicola and Jeremy Crossen for their valuable
contributions during an early implementation, and to Baktha
Muralidharan, Tom Petch, Dave Thaler and Bert Wijnen for their review
comments.
Special thanks to Joan Cucchiara and Len Nieman for their help with
compilation issues.
Joan Cucchiara provided a helpful and very thorough MIB Doctor
review.
11. IANA Considerations
-- (Note to RFC-Editor:)
-- We request that you assign contiguous RFC numbers to the three GMPLS
-- MIB documents.
-- The first number to draft-ietf-ccamp-gmpls-tc-mib, the second to
-- draft-ietf-ccamp-gmpls-lsr-mib, and the third to
-- draft-ietf-ccamp-gmpls-te-mib.
-- (Please remove this note prior to publication.)
IANA is requested to root MIB objects in the MIB module contained in
this document under the mplsStdMIB subtree.
In the future, GMPLS related standards track MIB modules should be
rooted under the mplsStdMIB (sic) subtree. IANA has been requested to
manage that namespace in the SMI Numbers registry [RFC3811]. New
assignments can only be made via a Standards Action as specified in
[RFC2434].

Internet Draft draft-ietf-ccamp-gmpls-te-mib-10.txt October 2005
11.1. IANA Considerations for GMPLS-TE-STD-MIB
The IANA is requested to assign { mplsStdMIB XXX } to the
GMPLS-TE-STD-MIB module specified in this document, and to record
the assignment in the SMI Numbers registry.
-- RFC Editor. Please replace XXX above with assigned OID and remove
-- this note
11.2. Dependence on IANA MIB Modules
Three MIB objects in this MIB module (gmplsTunnelLSPEncoding,
gmplsTunnelSwitchingType, and gmplsTunnelGPid) use textual
conventions imported from the IANA-GMPLS-TC-MIB. The purpose of
defining these textual conventions in a separate MIB module is to
allow additional values to be defined without having to issue a new
version of this document. The Internet Assigned Numbers Authority
(IANA) is responsible for the assignment of all Internet numbers; it
will administer the values associated with these textual conventions.
The rules for additions or changes to the IANA-GMPLS-TC-MIB are
outlined in the DESCRIPTION clause associated with its
MODULE-IDENTITY statement.
The current versions of the IANA-GMPLS-TC-MIB can be accessed from
the IANA home page at: "http://www.iana.org/".
11.2.1. IANA-GMPLS-TC-MIB Definition
This is a temporary section intended to supply the base definition of
an IANA MIB module. The normal procedure is that this MIB module is
moved into the direct control of IANA, at which time this section
should be deleted from this document.
IANA is requested to assign an OID to the IANA-GMPLS-TC-MIB module
specified in this document as { transmission YYY }.
-- RFC Editor.
-- Please replace YYY above with assigned OID and remove this note.

DESCRIPTION
"This data type is used as the syntax of the
gmplsTunnelLSPEncoding object in the definition of
GMPLS-TE-STD-MIB's gmplsTunnelTable.
gmplsTunnelLSPEncoding is used to represent and control
the LSP encoding type of an LSP signaled by a GMPLS
signaling protocol.
This textual convention is strongly tied to the LSP
Encoding Types sub-registry of the GMPLS Signaling
Parameters registry managed by IANA. Values should be
assigned by IANA in step with the LSP Encoding Types
sub-registry and using the same registry management rules.
However, the actual values used in this textual convention
are solely within the purview of IANA and do not
necessarily match the values in the values in the LSP
Encoding Types sub-registry.

IANAGmplsAdminStatusInformation ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"This data type is used as the syntax of the
gmplsTunnelAdminStatusFlags object in the definition of
GMPLS-TE-STD-MIB's gmplsTunnelTable.
gmplsTunnelAdminStatusFlags determines the setting of the
Admin Status flags in the Admin Status object or TLV, as
described in RFC 3471. Setting this object to a non-zero
value will result in the inclusion of the Admin Status
object or TLV on signaling messages.
This textual convention is strongly tied to the Admin
Status Flags sub-registry of the GMPLS Signaling Parameters
registry managed by IANA. Values should be assigned by IANA
in step with the Admin Status Flags sub-registry and using
the same registry management rules. However, the actual
values used in this textual convention are solely within
the purview of IANA and do not necessarily match the values
in the values in the Admin Status Flags sub-registry.
-- RFC Editor / IANA note
-- At the time of writing, the referenced Admin Status Flags
-- sub-registry has not been created.
-- It is not requested in RFC 3471 (the base reference for this protocol
-- element). But it is requested in two I-Ds that are ahead of this MIB
-- module in the IETF process
-- draft-ietf-ccamp-gmpls-recovery-e2e-signaling
-- draft-ietf-ccamp-gmpls-alarm-spec
-- Note, however, that at this stage no request is made to IANA for the
-- definition of values in the textual convention to match any of the
-- Admin Status bits except those defined in RFC 3471. IANA is free to
-- define additional values but these will not be used by this MIB
-- module (although future MIB modules will doubtless use them).
--
-- RFC Editor. Please update the previous paragraph to use the correct
-- name for the new sub-registry as defined by IANA, and delete this
-- note.
The definition of this textual convention with the
addition of newly assigned values is published
periodically by the IANA, in either the Assigned
Numbers RFC, or some derivative of it specific to
Internet Network Management number assignments. (The
latest arrangements can be obtained by contacting the
