Internet-Draft The DYMO MIB November 2008
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 a
Dynamic MANET On-demand (DYMO) routing [I-D.ietf-manet-dymo] process.
The DYMO MIB also reports state information, performance metrics, and
notifications. In addition to configuration, this additional state
and performance information is useful to management stations
troubleshooting routing 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 Dynamic MANET On-demand (DYMO) routing protocol
[I-D.ietf-manet-dymo] is intended for use by mobile nodes in
wireless, multihop networks. DYMO determines unicast routes among
DYMO routers within the network in an on-demand fashion, offering
improved convergence in dynamic topologies.
A DYMO routers' MIB contains DYMO process configuration parameters
(e.g. interfaces), state information (e.g. sequence number),
performance counters (e.g. number of control messages), and
notifications.
Harnedy, et al. Expires May 7, 2009 [Page 3]
Internet-Draft The DYMO MIB November 2008
4.1. DYMO Management Model
This section describes the management model for the DYMO routing
protocol.
4.2. 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.
o Tunable Configuration Objects - objects whose values affect timing
or attempt bounds on the DYMO protocol.
o State Objects - automatically generated values which define the
current operating state of the DYMO protocol process in the
router.
o Statistics Objects - automatically generated values which help an
administrator or automated tool to assess the performance of the
DYMO protocol process on the router and the overall routing
performance within the DYMO routing domain.
5. Structure of the MIB Module
This section presents the structure of the DYMO MIB module. The
objects are arranged into the following groups:
o dymoMIBNotifications - defines the notifications associated with
the DYMO MIB. These are currently limited to notifications of
interface state changes.
o dymoMIBObjects - defines the objects forming the basis for the
DYMO MIB. These objects are divided up by function into the
following groups:
* Configuration Group - This group contains the DYMO objects that
configure specific options that determine the overall
performance and operation of the routing protocol for the
router device and its interfaces.
* State Group - Contains information describing the current state
of the DYMO process such as the DYMO routing table.
* Statistics Group - Contains objects which help to characterize
the performance of the DYMO process, typically statistics
Harnedy, et al. Expires May 7, 2009 [Page 4]
Internet-Draft The DYMO MIB November 2008
counters. There are two types of DYMO statistics: global
counters and per interface counters.
o dymoMIBConformance - defines minimal and full conformance of
implementations to this DYMO MIB.
5.1. Textual Conventions
The textual conventions used in the DYMO MIB are as follows. The
RowStatus textual convention is imported from RFC 2579 [RFC2579].
The DymoInterfaceOperStatus is defined within the DYMO MIB. This
contains the current operational status of the DYMO interface.
5.2. The Configuration Group
The DYMO device is configured with a set of controls. The list of
configuration controls for the DYMO device follow.
Protocol Tuning Configuration Parameters:
o MSG_HOPLIMIT
o ROUTE_TIMEOUT
o ROUTE_AGE_MIN_TIMEOUT
o ROUTE_AGE_MAX_TIMEOUT
o ROUTE_USED_TIMEOUT
o ROUTE_DELETE_TIMEOUT
o ROUTE_RREQ_WAIT_TIME
o RREQ_RETRIES
o UNICAST_MESSAGE_SENT_TIMEOUT
Protocol Configuration Tables:
o Interfaces - If DYMO_INTERFACES is set to other than all, then the
DYMO router must be told which interfaces to run the DYMO protocol
over. This is a table containing the interfaces and associated
information.
o Responsible Hosts - If RESPONSIBLE_ADDRESSES is set to other than
self address, then the DYMO router must be configured with the set
of host addresses for which it is to generate RREP messages.
Harnedy, et al. Expires May 7, 2009 [Page 5]
Internet-Draft The DYMO MIB November 2008
5.3. The State Group
The State Subtree reports current state information. State
information from the DYMO-MIB is contained in the 'Peers' Table.
5.3.1. Peers Table
The DYMO peers table contains a list of recently known DYMO peer
nodes participating in the rotuing within the DYMO MANET. These
entries age out after a preset time.
5.3.2. Routing Table
The DYMO routing table contains DYMO specific information related to
IP forwarding entries found in the node's IP forwarding table MIB.
DYMO additional information includes the sequence number associated
with the DYMO message which generated the forwarding table entry.
5.4. The Statistics Group
The Statisctics subtree reports primarily counters that relate to
DYMO protocol activity. The DYMO performance statistics consists of
per node and per interface objects:
o OwnSequenceNumber
o RREQ initiated
o RREQ sent
o RREQ received
o RREP initiated
o RREP sent
o RREP received
o RRER initiated
o RRER sent
o RRER received
o Per interface statistics table with the following entries:
* RREQ initiated
Harnedy, et al. Expires May 7, 2009 [Page 6]
Internet-Draft The DYMO MIB November 2008
* RREQ sent
* RREQ received
* RREP initiated
* RREP sent
* RREP received
* RRER initiated
* RRER sent
* RRER received
5.5. The Notifications Group
The Notifications Subtree contains the list of notifications
supported within the DYMO-MIB and their intended purpose or utility.
This group is currently contains a single notification object related
to status changes in DYMO interfaces.
6. 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.
6.1. 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 DYMO-MIB does not
duplicate those objects.
6.2. 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.
Harnedy, et al. Expires May 7, 2009 [Page 7]
Internet-Draft The DYMO MIB November 2008
6.3. 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 DYMO-MIB module IMPORTS objects from SNMPv2-SMI
[RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], and IF-MIB
[RFC2863]

8. 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
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
Harnedy, et al. Expires May 7, 2009 [Page 29]
Internet-Draft The DYMO MIB November 2008
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] writeable 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 unathorized parties)
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.
Harnedy, et al. Expires May 7, 2009 [Page 30]
Internet-Draft The DYMO MIB November 2008
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.
9. 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:
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
Harnedy, et al. Expires May 7, 2009 [Page 31]
Internet-Draft The DYMO MIB November 2008
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.

Appendix B. Open Issues
This section contains the set of open issues related to the
development and design of the DYMO-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.
1. Agree on set of configuration options to be supported, e.g.,
Gateway config, local hosts, responsible addresses, etc.
2. Will DYMO require an MANET_ID (Instance ID) for running multiple
DYMO processes over the same interfaces?
3. Incorporate MIB-II IfGroup interworking with DymoIfTable.
4. Incorporate MIB-II IpGroup interworking with DymoIfTable.
5. Incorporate MIB-II IpForwardingGroup interworking with
DymoRoutingTable.
6. What performance objects are of interest and utility?
7. What notifications are of interest and utility?
