Abstract This document describes a management information base for the IS-IS Routing protocol, as described in ISO 10589 [2], when it is used to construct routing tables for IP networks, as described in RFC 1195 [RFC1195]. This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. This memo is based on an IETF draft by Chris Gunner [1]. This version has been modified to include MIB-II syntax, to exclude portions of the protocol that are not relevant to IP, such as the ES-IS protocol, and to add management support for current practice. 3.

Full Copyright Statement............................. 83 4. Overview This document is provided to the IETF working group on IS-IS. The IS-IS MIB includes of the following objects System-wide Attributes - isisSystem This table contains information specific to a single instance of the IS-IS protocol running on a router. - isisManAreaAddr Jeff Parker - Expires Feb 2003 [Page 2] Internet Draft - draft-ietf-isis-wg-mib-09.txt August 2002 This table includes area addresses manually configured which are used to control the associations formed between Level 1 Intermediate Systems. - isisAreaAddr This table includes area addresses reported in relevant L1 LSPs. - isisSysProtSupp This table includes the manually configured list of protocols, such as IP or CLNS, supported by the Intermediate System. - isisSummAddr This table holds summary addresses configured for each Level 2 instance of the IS-IS protocol running on a router. Circuit-specific Attributes - isisCirc This table contains information specific to a broadcast or point-to-point interface in the system. - isisCircLevel This table contains information specific to a one Level 1 or Level 2 of an interface. Counters - isisSystemCounter Counters in the System table, such as times we have wraped a sequence counter on one of our Link State PDUs. - isisCircuitCounter Counters of events particular to a circuit, such as PDUs with an illegal value of the System ID field length. - isisPacketCounter Jeff Parker - Expires Feb 2003 [Page 3] Internet Draft - draft-ietf-isis-wg-mib-09.txt August 2002 Counts of ISIS Protocol PDUs broken down into packet type. Attributes associated with an Adjacency - isisISAdj This table contains information about adjacencies to routers maintained by the protocol. Entries in this table cannot be created by management action: they are established through the Hello protocol. - isisISAdjAreaAddr This table contains the set of Area Addresses of neighboring Intermediate Systems as reported in IIH PDUs. - isisISAdjIPAddr This table contains the set of IP Addresses of neighboring Intermediate Systems as reported in received IIH PDUs. - isisISAdjProtSupp This table contains the set of protocols supported by neighboring Intermediate Systems as reported in received IIH PDUs. Attributes associated with configured addresses - isisRA The Reachable Address Table. This table contains information about an address prefix manually configured on the system or learned through another protocol. - isisIPRA The IP Reachable Address Table. This table contains information about IP reachable address manually configured on this system or learned from another protocol. Jeff Parker - Expires Feb 2003 [Page 4] Internet Draft - draft-ietf-isis-wg-mib-09.txt August 2002 Attributes associated with a Notification - isisNotification This table defines attributes that will be included when reporting IS-IS notifications. The SNMP Management Framework presently consists of five major components: An overall architecture, described in RFC 2571 [RFC2571]. 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]. 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]. 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]. A set of fundamental applications described in RFC 2573 [RFC2573] and the view-based access control mechanism described 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 Jeff Parker - Expires Feb 2003 [Page 5] Internet Draft - draft-ietf-isis-wg-mib-09.txt August 2002 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. 5. Definition of IS-IS MIB -- Changes in version 09 -- Remove isisCircMCAddr. Token Ring now uses proper MCast addresses -- Fixed order of indicies in isisIPRATable -- Added WideMetric and FullMetric to compliment DefaultMetric -- Added these to several objects -- Dropped AdminState from isisSummAddrTable. Only L1 to L2 makes sense -- Added isisRedistributeAddrTable to manage Domain Wide Prefixes -- Replace isisISAdjProtSuppIndex with isisISAdjIndex -- Moving counters to a new subtree. Have three types -- { system, level } - System wide -- { system, circuit, level } - per circuit specific -- { system, circuit, level, direction } - PDU counts -- Removed MaxAreaCheck. All implementations should check -- Moved isisSysExistState -- Replaced isisCircLevelLANDesISChanges with isisCircLANDesISChanges -- Restored definition of ManualOrAutomatic behavior -- More objects include the ManualOrAutomatic behavior -- Remove definition of OperationalState behaviour -- Fixed "may set the state to 'waiting'" rather than wait -- Changed syntax of isisCircSmallHellos from AdminState to TruthValue -- AdminState values swapped to line up with RFC 2863 -- CircuitID is always 7 bytes -- Formating changes to regularize spacing. -- Replaced isisCircPtToPtCircID with isisCircLevelCircID -- Removed isisISAdjAreaAddress as an index to isisISAdjAreaAddrTable.

Acknowledgments This draft MIB is based on a March 1994 Internet Draft by Chris Gunnerr, who should be held blameless for the errors introduced since Jeff Parker - Expires Feb 2003 [Page 79] Internet Draft - draft-ietf-isis-wg-mib-09.txt August 2002 then. We would like to thank the following individuals for constructive and valuable comments: Neal Castagnoli, Ken Chapman, Satish Dattatri, Les Ginsberg, Jeff Gross, Jim Halpin, Dimitri Haskin, Peter Higginson, Gavin McPherson, Kay Noguchi, Serge Maskalik, Jeff Pickering, Swaminatha Ramalingam, Aravind Ravikumar, Juergen Schoenwaelder, Koen Vermeulen, and Hans De Vleeschouwer. 7. Security Considerations Certain management information defined in this MIB may be considered sensitive in some network environments. 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. Therefore, authentication of received SNMP requests and controlled access to management information should be employed in such environments. 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.
