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) [2] devices. Since TRIP [2] is modelled after the Border Gateway Protocol (BGP-4) [3], 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 [4]. 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.

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 RFC-2119 [5]. 3. The SNMP Management Framework The SNMP Management Framework presently consists of five major components: - An overall architecture, described in RFC 2271 [6]. - 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 [7], STD 16, RFC 1212 [8] and RFC 1215 [9]. The second version, called SMIv2, is described in STD 58, RFC 2578 [10], RFC 2579 [11] and RFC 2580 [12]. - Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in RFC 1157 [13]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [14] and RFC 1906 [15]. The third version of the message protocol is called SNMPv3 and described in RFC 2272 [16] and RFC 2274 [17]. - Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in STD 15, RFC 1157 [13]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [18]. - A set of fundamental applications described in RFC 2273 [19] and the view-based access control mechanism described in RFC 2275 [20]. 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. Walker/Zinman 2 Internet Draft TRIP MIB March 2001 4. Overview Telephony Routing over IP (TRIP) [2] is an inter-domain application- layer control protocol that exchanges information with other TRIP gateways to provide efficient IP telephony routing. This MIB provides some managed objects for TRIP devices defined in Telephony Routing over IP <draft-ietf-iptel-trip-04.txt> and Authentication Attribute for TRIP <draft-ietf-iptel-authen-00.txt> [21]. 5. Structure of TRIP MIB This MIB utilizes the framework described in RFC 2788 [22] 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 Authentication Mechanism Table, the Trip Peer Table, the Trip Peer Stats Table, the Trip Route Table, the Trip Route Community Table, the Trip ITAD Topology Table, and the Trip ITAD Topology ID Table. The Trip Authentication Mechanism Table contains the authentication mechanism and the public key to broadcast. 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 Route Community Table contains information on the communities associated with each route. 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. 5.1. Textual Conventions The data types TripItad and TripId are used as textual conventions in this document. A TRIP ITAD is described in [2]. A TRIP ID is used as a distinct identifier for a TRIP entity. A TripPublicKey defines a key broadcast in an authentication transaction. 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 Walker/Zinman 3 Internet Draft TRIP MIB March 2001 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. Walker/Zinman 31 Internet Draft TRIP MIB March 2001 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 [23] and the View-based Access Control Model RFC 2575 [20] 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. Revision History 8.1. Changes from <draft-zinman-trip-mib-00.txt> o Removed tripRouteAddressLen from the tripRouteTable. o Made use of INET-ADDRESS-MIB and it's TC's for IPv6 compliance. o Changed order of the enumeration of tripPeerSendReceiveMode to comform to TRIP draft. o Added objects tripPeerCircuitCapacity and tripPeerDSPCapacity to support TRIP for Gateways [24]. o Removed tripPeerLastError and tripPeerState objects for tripEstablished notification. o Added local community object. o Added communities table for TRIP routes and removed community object from route table. o Added send/receive capability to local LS. o Added tripRouteAddressFamily as an Index to TripRouteEntry. o Changed enumerations in tripRouteAddressFamily to decimal(1) and hexaDecimal(2). o Support for authentication mechanism from draft-ietf-iptel-trip- authen-00.txt. o changed name of tripRoutePathSegment to tripRouteRoutedPathSegment. o Added tripRouteConverted to the routing table to signify a Converted Route. o Changed DEFVAL of tripPeerConnectRetryInterval from 60 to 120 seconds. o Added DEFVAL to tripPeerKeepAlive of 30 seconds. o Added DEFVAL to tripMaxPurgeTime and tripPeerMaxPurgeTime of 10 seconds. o Added DEFVAL to tripDisableTime and tripPeerDisableTime of 180 seconds. o Changed DEFVAL of tripMinItadOriginationInterval and tripPeerMinItadOriginationInterval to 30 seconds. o Removed tripHoldTimeConfigured and tripKeepAliveConfigured from TripCfgEntry. o changed names from opMode to sendReceiveMode.
