Internet-Draft   Mobile IP MIB Definition using SMIv2        April 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 managed objects used for managing the
   Mobile Node, Foreign Agent and Home Agent of the Mobile IP Protocol.

   This memo is intended to update and possibly obsolete RFC 2006,
   however, it is designed to be backward compatible

   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 RFC2119 [RFC2119].

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. Structure of the MIB

   This memo defines a portion of the Management Information Base (MIB)
   for the use with network management protocols in the Internet
   community.  In particular, it describes managed objects for the
   Mobile IP Protocol (MIP), as defined in [RFC3344].

3.1. Structure of the Mobile IP

   This section describes the basic model of Mobile IP used in
   developing the Mobile IP MIB. This information should be useful to
   the implementer in understanding some of the basic design decisions
   of the MIB.

   The Mobile IP Protocol introduces these new functional entities:

   Mobile Node

Internet-Draft   Mobile IP MIB Definition using SMIv2        April 2009


      A host or router that changes its point of attachment from one
      network or subnetwork to another.  A mobile node may change its
      location without losing connectivity and without changing its IP
      address; it may continue to communicate with other Internet nodes
      at any location using its (constant) IP address, assuming link-
      layer connectivity to a point of attachment is available.

   Home Agent

      A router on a mobile node's home network which tunnels packets for
      delivery to the mobile node when it is away from home, and
      maintains current location information for the mobile node.

   Foreign Agent

      A router on a mobile node's visited network which provides routing
      services to the mobile node while registered.  The foreign agent
      detunnels and delivers packets to the mobile node that were
      tunneled by the mobile node's home agent. For datagrams sent by a
      mobile node, the foreign agent may serve as a default router for
      registered mobile nodes.

   This document specifies the objects used in managing these entities;
   namely, the Mobile Node, the Home Agent, and the Foreign Agent.

3.2. MIB Groups

   Objects in this MIB are arranged into groups.  Each group is
   organized as a set of related objects.  The overall structure and the
   relationship between groups and the Mobile IP entities are shown
   below:

           Groups            Mobile Node  Foreign Agent  Home Agent

      MipSystemGroup            X               X             X
      MipSecAssociationGroup2   X               X             X
      MipSecViolationGroup2     X               X             X
      MnSystemGroup2            X
      mnDiscoveryGroup          X
      mnRegistrationGroup2      X
      maAdvertisementGroup2                     X             X
      maAdvertisementNAIGroup                   X             X
      faSystemGroup                             X
      faAdvertisementGroup2                     X
      faRegistrationGroup2                      X
      haRegistrationGroup2                                    X
      haRegNodeCountersGroup2                                 X

3.3. Protocol Extensions

   Apart from changes to base specification of Mobile IP [RFC3344], it
   has been enhanced in number of ways through its ability for added
   capabilities.  Implementations of those capabilities have not been
   able to have any management capabilities present in RFC 2006
   compliant [RFC2006] MIB module agents, since the capabilities
   themselves postdated the adoption of RFC 2006.  For several
   significant capabilities, in the form of NAI extension [RFC2794],
   Challenge/Response Extensions [RFC4721], Reverse Tunneling [RFC3024],
   Vendor/Organization-Specific Extensions [RFC3115] and Extensions for
   carrying NAI [RFC3846], the MIB Module defined in this document
   exposes object types to manage those extended capabilities and their
   operation.

   NAI extension requires a thorough redefinition of MIB table row
   indices from the RFC 2006 state since it provides a one more way to
   identify the mobile nodes apart from home address.  The functional
   differences between this memo and RFC 2006 [RFC2006] are explained in
   Appendix A.

3.4. Textual Conventions

   The RegistrationFlags, MipEntityIdentifierType, MipEntityIdentifier,
   MipEntityIdentifierNAI and MipDeliveryStyle are used as textual
   conventions in this document.  These textual conventions are used for
   the convenience of humans reading the MIB.  Objects defined using
   these conventions are always encoded by means of the rules that
   define their primitive type.  However, the textual conventions
   havecspecial semantics associated with them.  Hence, no changes to
   the SMI or the SNMP are necessary to accommodate these textual
   conventions which are adopted merely for the convenience of readers.

5. Security Considerations

   There are a number of management objects defined in this MIB that
   have 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.

   There are a number of managed objects in this MIB that may contain
   sensitive information. These are contained in the
   mipSecurityAssocTable, mipSecurityViolationTable, faRegVisitorTable,
   and haMobilityBindingTable. It is thus important to control even GET
   and/or NOTIFY access to these objects and possibly to even encrypt
   the values of these object when sending them over the network via
   SNMP.

   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.

   The Mobile IP MIB affords the network operator the ability to
   configure and control the Mobile IP links of a particular system,
   including the Mobile IP authentication protocols, and shared secret
   key. This represents a security risk.

   These risks are addressed in the following manners:

   1. All variables which represent a significant security risk are
      placed in separate MIB Groups.  By providing Agent Capability
      Statements, the implementor of the MIB may elect not to implement
      these groups.

Internet-Draft   Mobile IP MIB Definition using SMIv2        April 2009


   2. The MIB allows the manager station to create the security
      association for Mobile IP entities.  However, the agent should
      always return 0 length octet string when the manager station
      retrieves the shared security key in the mipSecAssocTable.  In
      this way, the Mobile IP entities can prevent the key leaking from
      SNMP GET, GET-NEXT, or GET-BULK requests.

   3. The MIB defines a trap for Mobile IP entities to send a
      notification to the manager station if there is a security
      violation.  In this way, the operator can notice the source of an
      intruder.

   4. The MIB also defines a table to log the security violations in the
      Mobile IP entities.  The manager station can retrieve this log to
      analyze the security violation instances in the system.

   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

   The MIB module in this document uses the following IANA-assigned
   OBJECT IDENTIFIER values recorded in the SMI Numbers registry:

         Descriptor        OBJECT IDENTIFIER value
         ----------        -----------------------

         mipMIB            { mib-2 44 }

   Editor's Note (to be removed prior to publication):  this draft makes
   no additional requests of the IANA.

APPENDIX A: Changes from RFC 2006

   There has been a substantial update of this MIP-MIB since RFC2006.
   However, sometimes backwards compatibility is preferred over
   perfection. So, some mib peculiarities still exist in this mib.

   RFC2006 had some index elements with read access. Although this is
   not recommended, these index object are not made not-accessible. The
   non deprecated objects are mnRegAgentAddress and mnRegCOA of row
   mnRegistrationEntry; and haMobilityBindingMN and haMobilityBindingCOA
   of row haMobilityBindingEntry. To get a clean compile with smilint,
   use the "-i index-element-accessible" option.

   RFC2006 had BITS constructs for RegistrationFlags and the mnAdvFlags
   that made sense in relation to RFC2002 but was hard to extend to in
   relation to the bits flags used in RFC3344. The editors have decided
   that backwards compatibility and not deprecate more objects than
   necessary is more important than a direct relation to the flags in
   later MIP RFCs. Extra care should be taken when RegistrationFlags and
   mnAdvFlags are implemented.

A.1. Changes in draft-ietf-mobileip-rfc2006bis-00

      - Section "The Network Management Framework" was updated.
      - Subsection Protocol Extensions was created under Overview
        section.
      -  Section Security Considerations was updated.
      -  Changes to the MIB definition are following.  Changes are
         listed in the order of their occurrence in the MIB definition.

      (1)  The textual convention RegistrationFlags was updated.  The
           bit for VJ compression was removed and bit for reverse
           tunneling was added.

           Three new textual conventions were added :
           MipEntityIdentifierType, MipEntityIdentifier and
           MipEntityIdentifierNAI. These
           textual conventions were defined to take into account that
           mobile nodes can be identified by other than ipaddress.

      (3)  New textual convention MipDeliveryStyle was added to
           represent the delivery style requested by mobile node in the
           registration request.
           mipSecAssocTable was deprecated and replaced with
           mipSecurityAssocTable to support the mobile nodes identified
           by NAI.  Indices of the table were changed.
           mipSecurityStatus object was added

           to manage the creation of new security associations in the
           table.  Default value clause was added to following three
           objects of the new table.
           - mipSecurityAlgorithmType
           - mipSecurityAlgorithmMode
           - mipSecurityReplayMethod

           hmac was added to the enumeration list of
           mipSecurityAlgorithmMode object.

      (5)  A new object mipSecurityAssocsCount was added. This gives the
           number of security associations in the mipSecurityAssocTable.

      (6)  mipSecViolationTable was deprecated and replaced with
           mipSecurityViolationTable to support the mobile nodes
            identified by NAI.
           Indices of the table were changed.The objects corresponding
           to mipSecRecentViolationIDLow and mipSecRecentViolationIDHigh
           in the new table are changed to have the syntax of Unsigned32
           instead of Integer32.

      (7)  Description of the mnHomeAddress object was changed to
           support dynamic home address assignment and default value
           clause was added.

      (8)  Two new objects mnIdentifierType and mnIdentifier were added
           to the mnSystem group.

      (9)  object mnAdvFlags was refined.  The bit for VJ compression
           was removed and bit for reverse tunneling was added.

      (10) Lower limit of value-range for objects mnAdvMaxRegLifetime
           and mnAdvMaxAdvLifetime is changed to 1 from 0.

      (11) A new object mnRegDeliveryStyle was added to the mnRegistra-
           tionTable

      (12) maAdvConfigTable was deprecated and replaced with
           maAdvertConfTable to support configuration of advertisement
           parameters on unnumbered interfaces.
           Index of the table was changed.  A new
           object maAdvertService was added to maAdvertConfTable to
           indicate the mobility services offered on the network
           interface.

      (13) objects faIsBusy and faRegistrationRequired were deprecated,
           replaced with faAdvertConfTable.  This is to allow for

           different settings of 'B' and 'R' bit on different network
           interfaces.

      (14) A new object faChallengeWindow was added to the faAdvertCon-
           fTable to allow for configuration of challenge window.

      (15) faVisitorTable was deprecated and replaced with faRegVisi-
           torTable to support the visitors identified by NAI.Indices of
           the table were changed. The objects corresponding to
           faVisitorRegIDLow and faVisitorRegIDHigh in the new table
           are changed to have the syntax of Unsigned32 instead of
           Integer32.

      (16) A new object faRegVisitorDeliveryStyle was added to the
           FaRegVisitorTable to indicate the delivery style requested by
           the mobile node.

      (17) A new object faRegVisitorCount was added to count the number
           of entries in faRegVisitorTable.

      (18) faVJCompressionUnavailable object was deprecated.

      (19) Five new counters specific to reverse tunneling function in
           for eign agent were added to faRegistration group.  These
           objects are
           - faReverseTunnelUnavailable
           - faReverseTunnelBitNotSet
           - faMnTooDistant
           - faDeliveryStyleUnsupported
           - faNonZeroHomeAddressRequired

      (20) Three new counters specific to agent advertisement challenge
           extension were added to faRegistration group. These objects
           - faUnknownChallenge
           - faMissingChallenge
           - faStaleChallenge

           was changed to Unsigned32 from Integer32.

      (23) haCounterTable was deprecated and replaced with haRegCoun-
           terTable to support the MNs identified by NAI.  Indices
           of the table were changed. The syntax of object corresponding
           to haRecentServiceDeniedCode in the new table was changed to
           add more error codes.
      (24) Three new counters specific to reverse tunneling function in
           home agent were added to the haRegistration group.  These
           objects are

           number of entries in haMobilityBindingTable.

      (27) mipAuthFailure notification was deprecated and replaced with
           mipAuthFailure2.

      (28) Compliance statement mipCompliance was deprecated and
           replaced with mipCompliance2.

      (29) Conformance groups were depreciated as needed due to the fact
           that many new items have been added to the MIB.  These groups
           include:
           -mipSecAssociationGroup

A.3. Changes in draft-ietf-mobileip-rfc2006bis-03

   (1) The size of the MipEntityIdentifier is changed to OCTET STRING of
   size 64 octets

   (2) Changed the SYNTAX for mnAdvSequence object to Integer32

   (3) Changed the SYNTAX for mnAdvMaxRegLifeTime object to Integer32

   is allowed for MIB revision. (RFC 2578, section 10.2 and RFC4181,
   section 4.9).

   3) mipSecurityAssocEntry and mipSecurityViolationEntry now contain
   the full NAI and the address objects. Since the index could be either
   or, and the NAI could be crippled in the index.

   4) The error code for a security violation is added. The reason
   object itself isn't enough (it's almost always other(6). Added
   mipSecRecentViolationErrorCode to mipSecViolationTable

   5) maAdvertIfIndex should be InterfaceIndex from IF-MIB, not integer

   6) With RFC3846, NAI is equally applicable to links and
   adverticements. So, NAI needs to be included for Mobility agent
   advertisement interfaces.

   Added in a group for those that implement agent NAI's a'la RFC3846.

   7) NAI needs to be added in the FA Visitor table. The NAI isn't
   necessarily included in the index, and it might also be crippled if
   it's to long.

   8) Packet and byte conters per session added. This is a most useful
   debug-tool, and is also practice in all comparable mibs. They should
   be kept per registration sessson in the FA and HA.

   9) HA and NAI information is included in haMobilityBindingTable.
   There could be many per snmp-agent, so which ha a particular ha
   session is pertaining to should be incluided in the table. Also, the
   NAI (as described before) is included.

   10) haRegRecentServiceDeniedCode can't be enumerated. It's handled by
   IANA and should therefore be one of the IANA considerations, the
   sytax is changed to open Integer32.

   11) The mipAuthFailure2 notification needs additional objects. Traps
   should be complete and don't require addditional read operations. the
   mipAuthFailure2 trap adds objects from hte seviolation table.

   12) StorageType a'la rfc2579 is added to those tables where they are
   needed.

   13) Updated template stuff, such as mib boiler plate, security
   considerations, references and TC conventions.
