Abstract

   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 a set of managed objects that are used to
   manage for Telephony Routing over IP (TRIP) [17] devices.

   Since TRIP [17] is modelled after the Border Gateway Protocol (BGP-4)
   [20], the managed objects for TRIP are also modelled after RFC1657 -
   Definitions of Managed Objects for the Fourth Version of the Border
   Gateway Protocol (BGP-4) using SMIv2 [21].

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 a set of managed objects that
   are used to schedule management operations periodically or at
   specified dates and times.


   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 [16].

2. The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

   - An overall architecture, described in RFC 2271 [1].

   - Mechanisms for describing and naming objects and events for the
     purpose of management. The first version of this Structure of
     Management Information (SMI) is called SMIv1 and described in
     STD16, RFC 1155 [2], STD 16, RFC 1212 [3] and RFC 1215 [4]. The
     second version, called SMIv2, is described in STD 58, RFC 2578 [5],
     RFC 2579 [6] and RFC 2580 [7].

   - Message protocols for transferring management information.  The
     first version of the SNMP message protocol is called SNMPv1 and
     described in RFC 1157 [8]. A second version of the SNMP message
     protocol, which is not an Internet standards track protocol, is
     called SNMPv2c and described in RFC 1901 [9] and RFC 1906 [10]. The
     third version of the message protocol is called SNMPv3 and
     described in RFC 2272 [11] and RFC 2274 [12].

   - Protocol operations for accessing management information. The first
     set of protocol operations and associated PDU formats is described
     in STD 15, RFC 1157 [8]. A second set of protocol operations and
     associated PDU formats is described in RFC 1905 [13].

   - A set of fundamental applications described in RFC 2273 [14] and
     the view-based access control mechanism described in RFC 2275 [15].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2. A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations. The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (use of Counter64). Some machine readable
   information in SMIv2 will be converted into textual descriptions in
   SMIv1 during the translation process. However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.


3. Overview


   Telephony Routing over IP (TRIP) [17] is an inter-domain application-
   layer control protocol that exchanges information with other TRIP
   gateways to provide efficiant IP telephony routing. This MIB provides
   some managed objects for SIP devices defined in
   draft-ietf-iptel-trip-03.txt.


4. Structure of TRIP MIB


Walker/Zinman                                                        2

Internet-Draft                 TRIP-MIB                 November, 2000




   This MIB utilizes the framework described in rfc2788 [19] for
   management of multiple instances of TRIP from a single entity. The
   Network Services Monitoring MIB applTable will be populated with
   entries corresponding to each TRIP entity in the system. Each entity
   will then have an applIndex associated with it. The value assigned to
   applIndex will represent the distinct instance of TRIP.

   The MIB defines some system-wide scalar objects local to the TRIP
   instance, as well as 5 tables: the Trip Peer Table, the Trip Peer
   Stats Table, the Trip Route Table, the Trip ITAD Topology Table, and
   the Trip ITAD Topology ID Table. The Trip Peer Table contains
   information about the state and current activity of the connections
   with TRIP peers. The Trip Peer Stats Table augments the Trip Peer
   Table and contains statistics related to the connections with TRIP
   peers. The Trip Route Table contains information on the route to a
   peers destination. The Trip ITAD Topology Table contains information
   on the sequence of link connections between peers within an ITAD. The
   Trip ITAD Topology ID Table is a subtable of the Trip ITAD Topology
   Table and contains the list of location servers within the ITAD
   domain that the instance of this trip ITAD Topology currently
   peering.

4.1 Textual Conventions


   The data types TripItad and TripId are used as textual conventions in
   this document. A TRIP ITAD is described in [17]. A TRIP ID is used as
   a distinct identifier for a TRIP table entity. These textual
   conventions have NO effect on either the syntax nor the semantics of
   any managed object.  Objects defined using these conventions are
   always encoded by means of the rules that define their primitive
   type.  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.

6. 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.

   The managed objects in this MIB contain sensitive information since,
   collectively, they allow tracing and influencing of connections in
   TRIP devices and provide information of their connection
   characteristics.

   It is thus important to control even GET access to these objects and
   possibly to even encrypt the values of these object when sending them
   over the network via SNMP. Not all versions of SNMP provide features
   for such a secure environment.

   SNMPv1 by itself is not a secure environment. 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.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework. Specifically, the use
   of the User-based Security Model RFC 2574 [18] and the View-based
   Access Control Model RFC 2575 [19] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, 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.
