Abstract
This memo defines a portion of the Management Information Base (MIB),
the network mobility support (NEMO) MIB, for use with network
management protocols in the Internet community. In particular, the
NEMO MIB will be used to monitor and control a mobile ipv6 node with
NEMO functionality.

Internet Draft July 16, 2005
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
2.1 The Mobile IPv6 Protocol and NEMO entities.
Mobile IPv6 (MIPv6) [RFC3775] specifies a protocol which allows nodes
to remain reachable while moving around in the IPv6 Internet. Network
Mobility Basic Support (NEMO) [RFC3963] is an extension to the Mobile
IPv6 protocol which facilitates the movement of an entire network.
The goals of Network Mobility support and related terminology are
discussed in [NEMOGOAL] and [NEMOTERM], respectively.
Typically mobile routers implement NEMO functionality for achieving
network mobility. However, a mobile router may also function as a
mobile node. In the context of this document, an entity that
implements the NEMO protocol is a NEMO entity.
This document defines a set of managed objects (MOs) that can be used
to monitor and control NEMO entities.
2.2 Implementation Guidance
This document focuses on the management of a NEMO entity. The
MIPv6MIB [10] defines the managed objects for a mobile node.
Implementations supporting both the mobile node and NEMO
functionality SHOULD implement the managed objects defined for the
NEMO entities and mobile nodes from both the MIPv6MIB and NEMOMIB.
Expires: January 15, 2006 [Page 3]
Internet Draft July 16, 2005
2.3 Terminology.
The terminology used in this document is consistent with the
definitions used in the Mobile IPv6 protocol specification[RFC3775]
and the NEMO Basic Support specification [NEMO].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14, RFC 2119 [RFC2119].
3. MIB Design
The NEMO MIB comprises of the following primary groups:
- nemoSystem
- nemoConfiguration
- nemoStats
- nemoNotifications
- nemoConformance
The nemoSystem group provides the general information of the NEMO
entity. The objects in this group cover the current home registration
state.
The nemoConfiguration group contains information relevant to the
implementation and operation of the NEMO protocol.
The nemoStats group defines the statistics related to the NEMO
protocol operations.
The nemoNotifications group defines the notifications generated by
the NEMO entity in response to the operationally interesting state
chanages in the NEMO protocol.
The nemoConformance group identifies the managed objects that needs
to be implemented for conforming to this draft.

5. Security Considerations
There are a number of management objects defined in this MIB module
with a MAX-ACCESS clause of read-write. 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:
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:
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.
6. IANA Considerations
IANA should assign a base arc in the mib-2 (standards track) OID tree
for the 'nemoMIB' MODULE-IDENTITY defined in the NEMO MIB.
