Internet-Draft The NHDP MIB November 2009
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 objects for configuring aspects of the
Neighborhood Discovery Protocol (NHDP) [NHDP] process on a router.
The NHDP MIB also reports state information, performance information
and notifications. This additional state and performance information
is useful to management stations troubleshooting neighbor discovery
problems.
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,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
3. Conventions
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 RFC 2119 [RFC2119].
4. Overview
The NHDP protocol allows routers in a Mobile Ad-Hoc Network (MANET)
to discover and track one-hop and two-hop neighbor sets. This
information is useful for routers running various routing and
multicast flooding protocols developed within the IETF MANET Working
Group.
4.1. Terms
The following definitions apply throughout this document:
o Configuration Objects - switches, tables, objects which are
initialized to default settings or set through the management
interface defined by this MIB.
Herberg, et al. Expires May 13, 2010 [Page 3]
Internet-Draft The NHDP MIB November 2009
o State Objects - automatically generated values which define the
current operating state of the NHDP protocol process in the
router.
o Performance Objects - automatically generated values which help an
administrator or automated tool to assess the performance of the
NHDP protocol process on the router and the overall discovery
performance within the NHDP domain.
5. Structure of the MIB Module
This section presents the structure of the NHDP MIB module. The MIB
is arranged into the following structure:
o nhdpNotifications - objects defining NHDP MIB notifications.
o nhdpObjects - defining objects within this MIB. The objects are
arranged into the following groups:
* Configuration Group - defining objects related to the
configuration of the NHDP instance on the device.
* State Group - defining objects which reflect the current state
of the NHDP instance running on the device.
* Performance Group - defining objects which are useful to a
management station when characterizing the performance of the
NHDP on the device and in the MANET.
o nhdpConformance - defining the minimal and maximal conformance
requirements for implementations of this MIB.
5.1. Textual Conventions
This section is TBD.
5.2. The Configuration Group
The device is configured with a set of controls. The list of
configuration controls for the NHDP-MIB (found in [NHDP]), are
discussed in the following subsections.
5.2.1. Interface Parameters
The Interface Parameters include:
Herberg, et al. Expires May 13, 2010 [Page 4]
Internet-Draft The NHDP MIB November 2009
5.2.1.1. Message Intervals
o HELLO_INTERVAL - is the maximum time between the transmission of
two successive HELLO messages on this MANET interface. If using
periodic transmission of HELLO messages, these SHOULD be at a
separation of HELLO_INTERVAL, possibly modified by jitter as
specified in [RFC5148].
o HELLO_MIN_INTERVAL - is the minimum interval between transmission
of two successive HELLO messages, on this MANET interface. (This
minimum interval MAY be modified by jitter, as defined in
[RFC5148].)
o REFRESH_INTERVAL - is the maximum interval between advertisements,
in a HELLO message on this MANET interface, of each 1-hop neighbor
network address and its status. In all intervals of length
REFRESH_INTERVAL, a router MUST include each 1-hop neighbor
network address and its status in at least one HELLO message on
this MANET interface. (This may be in the same or in different
HELLO messages.)
The following constraints apply to these interface parameters:
o HELLO_INTERVAL > 0
o HELLO_MIN_INTERVAL >= 0
o HELLO_INTERVAL >= HELLO_MIN_INTERVAL
o REFRESH_INTERVAL >= HELLO_INTERVAL
o If an INTERVAL_TIME message TLV as defined in [RFC5497] is
included in a HELLO message, then HELLO_INTERVAL MUST be
representable as described in [RFC5497].
The following default values are recommended:
o HELLO_INTERVAL := 2 seconds
o HELLO_MIN_INTERVAL := HELLO_INTERVAL/4
o REFRESH_INTERVAL := HELLO_INTERVAL
5.2.1.2. Information Validity Times
Parameters related to the Information Validity Times include:
Herberg, et al. Expires May 13, 2010 [Page 5]
Internet-Draft The NHDP MIB November 2009
o L_HOLD_TIME - is the period of advertisement, on this MANET
interface, of former 1-hop neighbor network addresses as lost in
HELLO messages, allowing recipients of these HELLO messages to
accelerate removal of this information from their Link Sets.
L_HOLD_TIME MAY be set to zero, if accelerated information removal
is not required.
o H_HOLD_TIME - is used as the Value in the VALIDITY_TIME Message
TLV included in all HELLO messages on this MANET interface. It is
then used by each router receiving such a HELLO message to
indicate the validity of the information taken from that HELLO
message and recorded in the receiving router's Information Bases.
The following constraints apply to these interface parameters:
o L_HOLD_TIME >= 0
o H_HOLD_TIME >= REFRESH_INTERVAL
o If HELLO messages can be lost then both SHOULD be significantly
greater than REFRESH_INTERVAL.
o H_HOLD_TIME MUST be representable as described in [RFC5497].
The following default values are recommended:
o H_HOLD_TIME := 3 x REFRESH_INTERVAL
o L_HOLD_TIME := H_HOLD_TIME
5.2.1.3. Link Quality
Parameters related to the Link Quality include:
o HYST_ACCEPT - is the link quality threshold at or above which a
link becomes usable, if it was not already so.
o HYST_REJECT - is the link quality threshold below which a link
becomes unusable, if it was not already so.
o INITIAL_QUALITY - is the initial quality of a newly identified
link.
o INITIAL_PENDING - if true, then a newly identified link is
considered pending, and is not usable until the link quality has
reached or exceeded the HYST_ACCEPT threshold.
The following constraints apply to these interface parameters:
Herberg, et al. Expires May 13, 2010 [Page 6]
Internet-Draft The NHDP MIB November 2009
o 0 < = HYST_REJECT < = HYST_ACCEPT < = 1
o 0 < = INITIAL_QUALITY < = 1.
o If link quality is not updated, then INITIAL_QUALITY >=
HYST_ACCEPT.
o If INITIAL_QUALITY >= HYST_ACCEPT, then INITIAL_PENDING := false.
o If INITIAL_QUALITY < HYST_REJECT, then INITIAL_PENDING := true.
Link quality is a mechanism whereby a router MAY take considerations
other than message exchange into account for determining when a link
is and is not a candidate for being considered as HEARD or SYMMETRIC.
As such, it is a "link admission" mechanism.
Link quality information for a link is generated (e.g., through
access to signal to noise ratio, packet loss rate, or other
information from the link layer) and used only locally, i.e. is not
included in signaling, and routers may interoperate whether they
areusing the same, different, or no, link quality information.
In order for a router to not employ link quality, the router MUST
define:
o INITIAL_PENDING := false
o INITIAL_QUALITY >= HYST_REJECT (there is no reason not to define
INITIAL_QUALITY := 1).
If link quality is changed, then parameter values will depend on the
link quality process. If link quality is not changed, then:
o HYST_ACCEPT := 1
o HYST_REJECT := 0
o INITIAL_QUALITY := 1
o INITIAL_PENDING := false
5.2.1.4. Jitter
If jitter, as defined in [RFC5148], is used then these parameters are
as follows:
Herberg, et al. Expires May 13, 2010 [Page 7]
Internet-Draft The NHDP MIB November 2009
o HP_MAXJITTER - represents the value of MAXJITTER used in [RFC5148]
for periodically generated HELLO messages on this MANET interface.
o HT_MAXJITTER - represents the value of MAXJITTER used in [RFC5148]
for externally triggered HELLO messages on this MANET interface.
For constraints on these interface parameters see [RFC5148].
The following default values are recommended:
o HP_MAXJITTER := HELLO_INTERVAL/4
o HT_MAXJITTER := HP_MAXJITTER
o C := 1/1024 second
5.2.2. Router Parameters
The following Router Parameters apply:
5.2.2.1. Information Validity Time
o N_HOLD_TIME - is used as the period during which former 1-hop
neighbor network addresses are advertised as lost in HELLO
messages, allowing recipients of these HELLO messages to
accelerate removal of this information from their 2-Hop Sets.
N_HOLD_TIME MAY be set to zero, if accelerated information is not
required.
o I_HOLD_TIME - is the period for which a recently used local
interface network address is recorded.
The following constraints applies to these router parameters:
o N_HOLD_TIME >= 0
o I_HOLD_TIME >= 0
5.3. The State Group
The State Subtree reports current state information, including
neighbor tables. These are separately discussed below.
The Local Information Base (LIB), contains the network addresses of
the interfaces (MANET and non-MANET) of this router. The contents of
this Information Base are not changed by signaling. The LIB contains
two tables:
Herberg, et al. Expires May 13, 2010 [Page 8]
Internet-Draft The NHDP MIB November 2009
o The "Local Interface Set", which records its local interfaces. It
consists of Local Interface Tuples, one per interface. Note that
the information from this set is contained in the
nhdpInterfaceTable, which is defined by this MIB document.
Therefore, the Local Interface Set is not defined as an object in
this MIB.
o The "Removed Interface Address Set", which records network
addresses which were recently used as local interface network
addresses. If a router's interface network addresses are
immutable then the Removed Interface Address Set is always empty
and MAY be omitted. It consists of Removed Interface Address
Tuples, one per network address.
The Interface Information Based (IIB), recording information
regarding links to this MANET interface and symmetric 2-hop neighbors
which can be reached through such links. The IIB contains two
tables:
o A "Link Set", which records information about current and recently
lost links between this interface and MANET interfaces of 1-hop
neighbors. The Link Set consists of Link Tuples, each of which
contains information about a single link. Recently lost links are
recorded so that they can be advertised in HELLO messages,
accelerating their removal from relevant 1-hop neighbors' Link
Sets. Link quality information, if used and available, is
recorded in Link Tuples and may indicate that links are treated as
lost.
o A "Two-Hop Set", which records the existence of bidirectional
links between symmetric 1-hop neighbors of this MANET interface
and other routers (symmetric 2-hop neighbors). The 2-Hop Set
consists of 2-Hop Tuples, each of which records an interface
address of a symmetric 2-hop neighbor, and all interface addresses
of the corresponding symmetric 1-hop neighbor. The 2-Hop Set is
updated by the signaling of this protocol, but is not itself
reported in that signaling.
The Neighbor Information Base (NIB), records information regarding
current and recently lost 1-hop neighbors of this router. The NIB
contains two tables:
o A "Neighbor Set", which records all network addresses of each
1-hop neighbor. It consists of Neighbor Tuples, each representing
a single 1-hop neighbor
o A "Lost Neighbor Set", which records network addresses of routers
which recently were symmetric 1-hop neighbors, but which are now
Herberg, et al. Expires May 13, 2010 [Page 9]
Internet-Draft The NHDP MIB November 2009
advertised as lost. It consists of Lost Neighbor Tuples, each
representing a single such network address
5.4. The Performance Group
The Performance Group reports values relevant to system performance.
This section lists objects for NHDP performance monitoring, some of
which explicitly appear in the NHDP-MIB and others which are
obtainable through a combination of base objects from this MIB and
reports available through the REPORT-MIB [REPORT]. Throughout this
section those objects will be pointed out that are intended as base
objects which will be explicitly defined within this MIB and those
objects which are derived through a combination of the base objects
and capabilities afforded by the REPORT-MIB.
The objects described in the following can be useful for determining
certain properties of the NHDP instance. Notably unstable neighbors
or 2-hop neighbors and frequent changes of sets can have a negative
influence on the performance of NHDP. The following objects thus
allow to acquire information related to the stability and performance
of NHDP:
The following objects return some of the statistics related to HELLO
messages:

difference between the histograms. For instance, that could
happen if suddenly many triggered HELLO messages are sent,
whereas before there have been only very few such triggered
messages.

6. Notifications
The Notifications Subtree contains the list of notifications
supported within the NHDP MIB and their intended purpose or utility.
This group is currently empty, pending further discussion.
7. Relationship to Other MIB Modules
[TODO]: The text of this section specifies the relationship of the
MIB modules contained in this document to other standards,
particularly to standards containing other MIB modules. Definitions
imported from other MIB modules and other MIB modules that SHOULD be
implemented in conjunction with the MIB module contained within this
document are identified in this section.
7.1. Relationship to the SNMPv2-MIB
The 'system' group in the SNMPv2-MIB [RFC3418] is defined as being
mandatory for all systems, and the objects apply to the entity as a
whole. The 'system' group provides identification of the management
entity and certain other system-wide data. The NHDP-MIB does not
duplicate those objects.
7.2. Relationship to the IF-MIB
[TODO] This section is included as an example; If the MIB module is
not an adjunct of the Interface MIB, then this section should be
removed.
Herberg, et al. Expires May 13, 2010 [Page 20]
Internet-Draft The NHDP MIB November 2009
7.3. MIB modules required for IMPORTS
[TODO]: Citations are not permitted within a MIB module, but any
module mentioned in an IMPORTS clause or document mentioned in a
REFERENCE clause is a Normative reference, and must be cited
someplace within the narrative sections. If there are imported items
in the MIB module, such as Textual Conventions, that are not already
cited, they can be cited in text here. Since relationships to other
MIB modules should be described in the narrative text, this section
is typically used to cite modules from which Textual Conventions are
imported.
The following NHDP MIB module IMPORTS objects from SNMPv2-SMI
[RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], and IF-MIB
[RFC2863]

9. Security Considerations
[TODO] Each specification that defines one or more MIB modules MUST
contain a section that discusses security considerations relevant to
those modules. This section MUST be patterned after the latest
approved template (available at
http://www.ops.ietf.org/mib-security.html). Remember that the
Herberg, et al. Expires May 13, 2010 [Page 61]
Internet-Draft The NHDP MIB November 2009
objective is not to blindly copy text from the template, but rather
to think and evaluate the risks/vulnerabilities and then state/
document the result of this evaluation.
[TODO] if you have any read-write and/or read-create objects, please
include the following boilerplate paragraph.
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 are the tables and objects and their
sensitivity/vulnerability:
o [TODO] writable MIB objects that could be especially disruptive if
abused MUST be explicitly listed by name and the associated
security risks MUST be spelled out; RFC 2669 has a very good
example.
o [TODO] list the writable tables and objects and state why they are
sensitive.
[TODO] else if there are no read-write objects in your MIB module,
use the following boilerplate paragraph.
There are no management objects defined in this MIB module that have
a MAX-ACCESS clause of read-write and/or read-create. So, if this
MIB module is implemented correctly, then there is no risk that an
intruder can alter or create any management objects of this MIB
module via direct SNMP SET operations.
[TODO] if you have any sensitive readable objects, please include the
following boilerplate paragraph.
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:
o [TODO] you must explicitly list by name any readable objects that
are sensitive or vulnerable and the associated security risks MUST
be spelled out (for instance, if they might reveal customer
information or violate personal privacy laws such as those of the
European Union if exposed to unauthorized parties)
Herberg, et al. Expires May 13, 2010 [Page 62]
Internet-Draft The NHDP MIB November 2009
o [TODO] list the tables and objects and state why they are
sensitive.
[TODO] discuss what security the protocol used to carry the
information should have. The following three boilerplate paragraphs
should not be changed without very good reason. Changes will almost
certainly require justification during IESG review.
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.
10. IANA Considerations
[TODO] In order to comply with IESG policy as set forth in
http://www.ietf.org/ID-Checklist.html, every Internet-Draft that is
submitted to the IESG for publication MUST contain an IANA
Considerations section. The requirements for this section vary
depending what actions are required of the IANA. see RFC4181 section
3.5 for more information on writing an IANA clause for a MIB module
document.
[TODO] select an option and provide the necessary details.
Option #1:
Herberg, et al. Expires May 13, 2010 [Page 63]
Internet-Draft The NHDP MIB November 2009
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
sampleMIB { mib-2 XXX }
Option #2:
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.
Note well: prior to official assignment by the IANA, a draft document
MUST use placeholders (such as "XXX" above) rather than actual
numbers. See RFC4181 Section 4.5 for an example of how this is done
in a draft MIB module.
Option #3:
This memo includes no request to IANA.
11. Contributors
This MIB document uses the template authored by D. Harrington which
is based on contributions from the MIB Doctors, especially Juergen
Schoenwaelder, Dave Perkins, C.M.Heard and Randy Presuhn.
12. Acknowledgements
[TODO]This acknowledgement can be removed from your MIB module
document.

Appendix A. Change Log
Here we list the changes made to the various drafts of this MIB.
We list here the changes made on the draft-ietf-manet-nhdp-mib-01
draft to generate the draft-ietf-manet-nhdp-mib-02 draft.
1. Cleaned up several things (e.g. moved N_HOLD_TIME from interface
parameter to router paramter)
2. Updated to NHDP draft version 11
Herberg, et al. Expires May 13, 2010 [Page 65]
Internet-Draft The NHDP MIB November 2009
We list here the changes made on the draft-ietf-manet-nhdp-mib-00
draft to generate the draft-ietf-manet-nhdp-mib-01 draft.
1. Made and extensive addition in the area of performance
monitoring. Added text in the front material, added a
PerformanceGroup to the MIB and added the PerformanceGroup to the
Conformance Sections.
We list here the changes made on the draft-cole-manet-nhdp-mib-01
draft to generate the draft-ietf-manet-nhdp-mib-00 draft.
1. Cleanup up numerous typos and add material to the Conformance
section in order to pass the MIB checker, i.e., smilint.
We list here the changes made on the draft-cole-manet-nhdp-mib-00
draft to generate the draft-cole-manet-nhdp-mib-01 draft.
1. Defined the NeighborIfIndex and the NeighborRouterId textual
conventions. These identify a remote neighbor IfIndex and a
remote neighbor router and are used as indexes into NHDP state
tables. These constructs were necessary in order to associate
address lists with specific remote interfaces as required by the
NHDP protocol specification.
2. Developed the nhdpInterfaceTable as part of the configuration
group.
3. Developed the nhdpDiscIfSetTable as a means to associate address
lists with remotely discovered neighbor interfaces.
4. Added tables defining the router's NHDP Local Information Base
(LIB) as specified in the NHPD protocol specification.
5. Added tables defining the router's NHDP Interface information
Base (IIB) as specified in the NHPD protocol specification.
6. Added tables defining the router's NHDP Neighbor Information Base
(NIB) as specified in the NHPD protocol specification.
7. Aligned the NHDP-MIB and the OLSRv2-MIB configuration tables and
indexing.
Appendix B. Open Issues
This section contains the set of open issues related to the
development and design of the NHDP-MIB. This section will not be
present in the final version of the MIB and will be removed once all
the open issues have been resolved.
Herberg, et al. Expires May 13, 2010 [Page 66]
Internet-Draft The NHDP MIB November 2009
1. How to handle dynamic parameters within NHDP? Should we expose
setting, min and max values?
2. Need to address how to handle Link Quality settings and
parameters for a) optional operation and b) changing nature of
link quality.
3. What notifications are of interest and utility?
4. Identify all objects requiring non-volatile storage in their
DESCRIPTION clauses.
5. Incorporate parameter relationship conditions into their
DESCRIPTION clauses.
6. Also, specify specific SNMP response to the snmp set request,
i.e., 'generic error', 'bad value', etc.
7. Fill in all of the DEFVAL within the configuration group
objects.
8. Run through the MIB checker.
9. Clean up all of the 'Note:' statements within the body of the
MIB.
10. Work on the Security Section. This MIB does have settable
objects, but not sensitive objects (true?).
11. Work on the relationship to other MIBs, IF-MIB, NHDP-MIB.
12. Cleanup all the [TODOs] from the MIB template.
