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. Since TRIP [RFC3219] is modeled after the Border Gateway Protocol (BGP-4) [RFC1771], the managed objects for TRIP are also modeled after RFC1657 - Definitions of Managed Objects for the Fourth Version of the Border Gateway Protocol (BGP-4) using SMIv2 [RFC1657]. 2. Conventions used in this document 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 BCP-0014 [BCP0014]. 3. The SNMP Management Framework The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2571 [RFC2571]. o 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 STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215 [RFC1215]. The second version, called SMIv2, is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in STD 15, RFC 1157 [RFC1157]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [RFC1901] and RFC 1906 [RFC1906]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [RFC1157]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [RFC1905]. o A set of fundamental applications described in RFC 2573 [RFC2573] and the view-based access control mechanism described Zinman/Walker/Jiang 3 Internet Draft October 2002 in RFC 2575 [RFC2575]. A more detailed introduction to the current SNMP Management Framework can be found in RFC 2570 [RFC2570]. 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. 4. Overview Telephony Routing over IP (TRIP) [RFC3219] is an inter-domain application-layer control protocol that exchanges information between TRIP location servers to provide efficient IP telephony routing. This MIB provides managed objects for TRIP devices defined in Telephony Routing over IP [RFC3219]. 5. Structure of TRIP MIB This MIB utilizes the framework described in RFC 2788 [RFC2788] 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 LS in the system. Each TRIP LS will then have an applIndex associated with it. The value assigned to applIndex will represent the distinct instance of TRIP. The TRIP MIB contains the following groups of objects: o The tripConfigGroup contains the common configuration objects applicable to all TRIP applications referenced by the applIndex. o The tripPeerTableConfigGroup contains the configuration objects applicable to all TRIP peers of the LS referened by the applIndex. o The tripRouteGroup contains the configuration objects related to the routes of all TRIBs of this LS. o The tripItadTopologyGroup contains information about the topology of the TRIP ITADs concerning this LS. o The tripPeerTableStatsGroup contains the statistical objects applicable to all TRIP peers of the LS referened by the applIndex. o The tripNotificationGroup contains notifications that the TRIP application can generate. o The tripNotifObjectGroup contains the objects needed by one or more of the notifications. Zinman/Walker/Jiang 4 Internet Draft October 2002 5.1 Textual Conventions The data types TripItad and TripId are used as textual conventions in this document. A TRIP ITAD is described in [RFC3219]. A TRIP ID is used as a distinct identifier for a TRIP LS. A TripAppProtocol is used to identify an application protocol. A TripAddressFamily is used to define an address family. TripCommunityId is used as a distinct identifier for a TRIP community. TripProtocolVersion depicts the version number of the TRIP protocol. TripSendReceiveMode describes the operational mode of the TRIP application. 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. Zinman/Walker/Jiang 39 Internet Draft October 2002 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 [RFC2574] and the View- based Access Control Model RFC 2575 [RFC2575] 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. 8.
