Description: Defines Cisco OSPF-specific SNMP trap notifications for link state and neighbor adjacency change events.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-OSPF-TRAP-MIB?

CISCO-OSPF-TRAP-MIB is a Cisco Systems proprietary MIB defining OSPF notification objects aligned with a later IETF OSPF MIB update draft, including support for OSPF sham-link notifications. Its objects cover a global trap-enable control, configuration-error type/packet type/source classification for a misconfigured interface or virtual interface, and notification triggers for LSA retransmission, origination, and max-age events. As a protocol-status/notification MIB it lets an administrator get alerted to OSPF interface misconfigurations and abnormal LSA churn (retransmits, max-age expirations) that often precede routing instability. It is deployed on Cisco routers running OSPF. Engineers can download the CISCO-OSPF-TRAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-OSPF-TRAP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco routers running OSPF

Monitoring Examples

An administrator investigates a cospfTxRetransmit notification alongside cospfIfConfigError for the same interface to determine whether a misconfiguration is causing repeated LSA retransmissions on an OSPF adjacency.

What Can Be Monitored

OSPF configuration-error and LSA retransmission/origination/max-age notifications

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoOspfTrapMIB	1.3.6.1.4.1.9.10.101			This MIB module describes new/modified notification objects/events, which are defined in the latest version for OSPF MIB IETF draft draftietf-ospf-mib-update-05.txt. Support for OSPF Sham link is also added
ciscoOspfTrapMIBNotifs	1.3.6.1.4.1.9.10.101.0
NTF cospfIfConfigError	1.3.6.1.4.1.9.10.101.0.1			A cospfIfConfigError trap signifies that a packet with mismatched parameter MTU has been received on a non-virtual interface from a router.
NTF cospfVirtIfConfigError	1.3.6.1.4.1.9.10.101.0.2			A cospfVirtIfConfigError trap signifies that a packet with mismatched parameter MTU has been received on a virtual interface from a router.
NTF cospfTxRetransmit	1.3.6.1.4.1.9.10.101.0.3			A cospfTxRetransmit trap signifies than an OSPF packet, which has been associated with an Opaque LSA LSDB Entry, has been retransmitted on a non-virtual interface.
NTF cospfVirtIfTxRetransmit	1.3.6.1.4.1.9.10.101.0.4			A cospfVirtTxRetransmit trap signifies than an OSPF packet, which has been associated with an Opaque LSA LSDB Entry, has been retransmitted on a non-virtual interface.
NTF cospfOriginateLsa	1.3.6.1.4.1.9.10.101.0.5			A cospfOriginateLsa trap signifies that a new Opaque LSA has been originated by this router. This trap should not be invoked for simple refreshes of LSAs (which happesn every 30 minutes), but instead will only be invoked when an LSA is (re)originated due to a topology change. Additionally, this trap does not include LSAs that are being flushed because they have reached MaxAge.
NTF cospfMaxAgeLsa	1.3.6.1.4.1.9.10.101.0.6			A cospfMaxAgeLsa trap signifies that one of the Opaque LSAs in the router's link-state database has aged to MaxAge.
NTF cospfNssaTranslatorStatusChange	1.3.6.1.4.1.9.10.101.0.7			A cospfNssaTranslatorStatusChange trap indicates that there has been a change in the router's ability to translate OSPF type-7 LSAs into OSPF type-5 LSAs. This trap should be generated when the Translator Status transitions from or to any defined status on a per area basis.
NTF cospfShamLinkStateChange	1.3.6.1.4.1.9.10.101.0.8			A ospfShamLinkStateChange trap signifies that there has been a change in the state of a Sham Link OSPF interface. This trap should be generated when the interface state regresses from Point-to-Point to Down or progresses to Down to Point-to-Point. This trap has been deprecated by cospfShamLinksStateChange.
NTF cospfShamLinkNbrStateChange	1.3.6.1.4.1.9.10.101.0.9			A cospfShamLinkNbrStateChange trap signifies that there has been a change in the state of a sham link OSPF neighbor. This trap should be generated when the neighbor state regresses (e.g., goes from Attempt or Full to 1-Way or Down) or progresses to a terminal state (e.g., Full).
NTF cospfShamLinkConfigError	1.3.6.1.4.1.9.10.101.0.10			A cospfShamLinkConfigError signifies that a packet has been received on a sham link from a router whose configuration parameters conflict with this router's configuration parameters.
NTF cospfShamLinkAuthFailure	1.3.6.1.4.1.9.10.101.0.11			A cospfShamLinkAuthFailure trap signifies that a packet has been received on a sham link from a router whose authentication key or authentication type conflicts with this router's authentication key and authentication type.
NTF cospfShamLinkRxBadPacket	1.3.6.1.4.1.9.10.101.0.12			A cospfShamLinkRxBadPacket trap signifies that an OSPF packet has been received on a sham link that cannot be parsed.
NTF cospfShamLinkTxRetransmit	1.3.6.1.4.1.9.10.101.0.13			A cospfShamLinkTxRetransmit trap signifies that an OSPF packet has been retransmitted on a sham link. All packets that may be retransmitted are associated with an LSDB entry. The LS type, LS ID, and Router ID are used identify the LSDB entry.
NTF cospfShamLinksStateChange	1.3.6.1.4.1.9.10.101.0.14			A ospfShamLinkStateChange trap signifies that there has been a change in the state of a Sham Link OSPF interface. This trap should be generated when the interface state regresses from Point-to-Point to Down or progresses to Down to Point-to-Point.
