ISIS-MIB
AI MIB Summary
The ISIS-MIB module enables monitoring of Intermediate System-to-Intermediate System (IS-IS) routing protocol instances on network devices, specifically tracking adjacency states, topology database synchronization, and LSP (Link State PDU) generation statistics for IP networks. It provides granular visibility into IS-IS session establishment failures, neighbor flapping events, and routing table consistency to facilitate the diagnosis of Layer 3 routing failures.
This document describes a management information base for the IS-IS Routing protocol, as described in ISO 10589, when it is used to construct routing tables for IP networks, as described in RFC 1195. This document is based on a 1994 IETF document by Chris Gunner. This version has been modified to include current syntax, to exclude portions of the protocol that are not relevant to IP, and to add management support for current practice. Copyright (C) The Internet Society (2006). This version of this MIB module is part of RFC 4444; see the RFC itself for full legal notices.

isisNotifications OBJECT IDENTIFIER .1.3.6.1.2.1.138.0 |
isisDatabaseOverloadThis notification is generated when the system enters or leaves the Overload state. The number of times this has been generated and cleared is kept track of by isisSysStatLSPDbaseOloads. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.1 |
isisManualAddressDropsThis notification is generated when one of the manual areaAddresses assigned to this system is ignored when computing routes. The object isisNotificationAreaAddress describes the area that has been dropped. The number of times this event has been generated is counted by isisSysStatManAddrDropFromAreas. The agent must throttle the generation of consecutive isisManualAddressDrops notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.2 |
isisCorruptedLSPDetectedThis notification is generated when we find that an LSP that was stored in memory has become corrupted. The number of times this has been generated is counted by isisSysCorrLSPs. We forward an LSP ID. We may have independent knowledge of the ID, but in some implementations there is a chance that the ID itself will be corrupted. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.3 |
isisAttemptToExceedMaxSequenceWhen the sequence number on an LSP we generate wraps the 32-bit sequence counter, we purge and wait to re-announce this information. This notification describes that event. Since these should not be generated rapidly, we generate an event each time this happens. While the first 6 bytes of the LSPID are ours, the other two contain useful information. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.4 |
isisIDLenMismatchA notification sent when we receive a PDU with a different value for the System ID Length. This notification includes an index to identify the circuit where we saw the PDU and the header of the PDU, which may help a network manager identify the source of the confusion. The agent must throttle the generation of consecutive isisIDLenMismatch notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.5 |
isisMaxAreaAddressesMismatchA notification sent when we receive a PDU with a different value for the Maximum Area Addresses. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. The agent must throttle the generation of consecutive isisMaxAreaAddressesMismatch notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.6 |
isisOwnLSPPurgeA notification sent when we receive a PDU with our systemID and zero age. This notification includes the circuit Index and router ID from the LSP, if available, which may help a network manager identify the source of the confusion. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.7 |
isisSequenceNumberSkipWhen we receive an LSP with our System ID and different contents, we may need to reissue the LSP with a higher sequence number. We send this notification if we need to increase the sequence number by more than one. If two Intermediate Systems are configured with the same System ID, this notification will fire. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.8 |
isisAuthenticationTypeFailureA notification sent when we receive a PDU with the wrong authentication type field. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. The agent must throttle the generation of consecutive isisAuthenticationTypeFailure notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.9 |
isisAuthenticationFailureA notification sent when we receive a PDU with an incorrect authentication information field. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. The agent must throttle the generation of consecutive isisAuthenticationFailure notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.10 |
isisVersionSkewA notification sent when we receive a Hello PDU from an IS running a different version of the protocol. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. The agent must throttle the generation of consecutive isisVersionSkew notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.11 |
isisAreaMismatchA notification sent when we receive a Hello PDU from an IS that does not share any area address. This notification includes the header of the packet, which may help a network manager identify the source of the confusion. The agent must throttle the generation of consecutive isisAreaMismatch notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.12 |
isisRejectedAdjacencyA notification sent when we receive a Hello PDU from an IS but do not establish an adjacency for some reason. The agent must throttle the generation of consecutive isisRejectedAdjacency notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.13 |
isisLSPTooLargeToPropagateA notification sent when we attempt to propagate an LSP that is larger than the dataLinkBlockSize for the circuit. The agent must throttle the generation of consecutive isisLSPTooLargeToPropagate notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.14 |
isisOrigLSPBuffSizeMismatchA notification sent when a Level 1 LSP or Level 2 LSP is received that is larger than the local value for isisSysLevelOrigLSPBuffSize, or when an LSP is received that contains the supported Buffer Size option and the value in the PDU option field does not match the local value for isisSysLevelOrigLSPBuffSize. We pass up the size from the option field and the size of the LSP when one of them exceeds our configuration. The agent must throttle the generation of consecutive isisOrigLSPBuffSizeMismatch notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.15 |
isisProtocolsSupportedMismatchA notification sent when a non-pseudonode segment 0 LSP is received that has no matching protocols supported. This may be because the system does not generate the field, or because there are no common elements. The list of protocols supported should be included in the notification: it may be empty if the TLV is not supported, or if the TLV is empty. The agent must throttle the generation of consecutive isisProtocolsSupportedMismatch notifications so that there is at least a 5-second gap between notifications of this type. When notifications are throttled, they are dropped, not queued for sending at a future time. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.16 |
isisAdjacencyChangeA notification sent when an adjacency changes state, entering or leaving state up. The first 6 bytes of the isisPduLspId are the SystemID of the adjacent IS. The isisAdjState is the new state of the adjacency. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.17 |
isisLSPErrorDetectedThis notification is generated when we receive an LSP with a parse error. The isisCircIfIndex holds an index of the circuit on which the PDU arrived. The isisPduFragment holds the start of the LSP, and the isisErrorOffset points to the problem. If the problem is a malformed TLV, isisErrorOffset points to the start of the TLV, and isisErrorTLVType holds the value of the type. If the problem is with the LSP header, isisErrorOffset points to the suspicious byte. The number of such LSPs is accumulated in isisSysStatLSPErrors. NOTIFICATION-TYPE .1.3.6.1.2.1.138.0.18 |

isisSysReceiveLSPBufferSizeSize of the largest buffer we are designed or configured to store. This should be at least as big as the maximum isisSysLevelOrigLSPBuffSize supported by the system. If resources allow, we will store and flood LSPs larger than isisSysReceiveLSPBufferSize, as this can help avoid problems in networks with different values for isisSysLevelOrigLSPBuffSize. Configured values MUST survive an agent reboot.rw IsisUnsigned16TC .1.3.6.1.2.1.138.1.1.1.11 |
isisSysProtSupportedThis attribute contains the set of protocols supported by this Intermediate System.ro Bits .1.3.6.1.2.1.138.1.1.1.12 |

isisManAreaAddrA manually configured area address for this system. Note: An index for the entry {1, {49.0001} active} in this table would be the ordered pair (1, (0x03 0x49 0x00 0x01)), as the length of an octet string is part of the OID. IsisOSINSAddress .1.3.6.1.2.1.138.1.1.2.1.1 |
isisManAreaAddrExistStateThe state of the isisManAreaAddrEntry. If the isisSysAdminState for this Intermediate System is 'on' and an attempt is made to set this object to the value 'destroy' or 'notInService' when this is the only isisManAreaAddrEntry in state 'active' for this Intermediate System should return inconsistentValue.

isisSysLevelStateThe state of the database at this level. The value 'off' indicates that IS-IS is not active at this level. The value 'on' indicates that IS-IS is active at this level and is not overloaded. The value 'waiting' indicates a database that is low on an essential resource, such as memory. The administrator may force the state to 'overloaded' by setting the object isisSysLevelSetOverload. If the state is 'waiting' or 'overloaded', we originate LSPs with the overload bit set.ro IsisLevelState .1.3.6.1.2.1.138.1.2.1.1.4 |
isisSysLevelSetOverloadAdministratively set the overload bit for the level. The overload bit MUST continue to be set if the implementation runs out of memory, independent of this variable.

isisNextCircIndexThis object is used to assist a management application in creating new rows in the isisCircTable. If it is possible to create a new instance of isisCircEntry, then this object will contain a non-zero value that is not in use as the index of any row in the isisCircTable. The network manager reads the value of this object and then (if the value read is non-zero) attempts to create the corresponding instance of isisCircEntry.
