Expires May 25, 2009 [Page 2] Internet-Draft NEMO Management Information Base November 2008 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 [RFC4886] and [RFC4885], 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 [RFC4295] 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. Sri Gundavelli, et al. Expires May 25, 2009 [Page 3] Internet-Draft NEMO Management Information Base November 2008 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 [RFC3963]. 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]. 2.4. MIB Design The NEMO MIB comprises of the following groups of definitions: - nemoCore: a generic group containing objects that are common to all the NEMO entities. - nemoHa: this group models the home agent service. It is composed of objects specific to the services and associated advertisement parameters offered by the home agent on each of its links. It also contains objects pertaining to the maintenance of the home agent list on each of the links on which the service is offered. - nemoMr: this group models the mobile router service. It is composed of objects specific to the Dynamic Home Agent discovery function and related parameters. It also contains objects that record the movement of the mobile router. - nemoNotifications: defines the set of notifications that will be used to asynchronously monitor the NEMO entities. The tables contained in the above groups are as follows: nemoBindingCacheTable : models the binding cache on the home agent and correspondent node. It contains details of the Binding Update requests that have been received and accepted. nemoMrEgressIfTable : contains information on the configured egress interfaces. nemoMrBLTable : models the Binding Update List on the mobile router. It contains information about the registration requests sent by the mobile router and the corresponding results. nemoHaCounterTable : contains registration statistics for all mobile routers registered with the home agent. Sri Gundavelli, et al. Expires May 25, 2009 [Page 4] Internet-Draft NEMO Management Information Base November 2008 nemoHaMobileNetworkPrefixTable : contains the list of the mobile network prefixes that are maintained by the home agent. 2.5.

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. 2.7. 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: nemoStatus: The value of this object is used to enable or disable the NEMO functionality on a NEMO entity. Access to this MO may be abused to disrupt the communication that depends on NEMO. nemoMrPrefixRegMode: The value of this object is used to control the mode in which mobile network prefixes will be registered with the home agent. Access to this object may be abused to disrupt the setting up of mobile network prefixes. 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 address-related objects in this MIB may be considered to be particularly sensitive and/or private. The mobile network prefix- related objects reveal the configuration of the mobile router. This information may be considered to be private Sri Gundavelli, et al. Expires May 25, 2009 [Page 41] Internet-Draft NEMO Management Information Base November 2008 and sensitive and must be carefully handled. nemoHaMobileNetworkPrefixType nemoHaMobileNetworkPrefix nemoHaMobileNetworkPrefixLength 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. 2.8.
