Feature Information for OSPF MIB Support of RFC 1850 and Latest Extensions

OSPF MIB Support of RFC 1850 and Latest Extensions

First Published: August 23, 2003

Last Updated: December 5, 2006

The OSPF MIB Support of RFC 1850 and Latest Extensions feature introduces the capability for Simple Network Management Protocol (SNMP) monitoring on the Open Shortest Path First (OSPF) routing protocol. Users have an improved ability to constantly monitor the changing state of an OSPF network by use of MIB objects to gather information relating to protocol parameters and trap notification objects that can signal the occurrence of significant network events such as transition state changes. The protocol information collected by the OSPF MIB objects and trap objects can be used to derive statistics that will help monitor and improve overall network performance.

Prerequisites for OSPF MIB Support of RFC 1850 and Latest Extensions

•OSPF must be configured on the router.

•Simple Network Management Protocol (SNMP) must be enabled on the router before notifications (traps) can be configured or before SNMP GET operations can be performed.

Restrictions for OSPF MIB Support of RFC 1850 and Latest Extensions

For routers that are running Cisco IOS Release 12.0(26)S, 12.2(25)S, 12.2(27)SBC, 12.2(31)SB2 and later releases, the OSPF MIB and CISCO OSPF MIB will be supported only for the first OSPF process (except for MIB objects that are related to virtual links and sham links, and in cases where support for multiple topologies is provided). SNMP traps will be generated for OSPF events that are related to any of the OSPF processes. There is no workaround for this situation.

Information About OSPF MIB Support of RFC 1850 and Latest Extensions

The following sections contain information about MIB objects standardized as part of RFC 1850 and defined in OSPF-MIB and OSPF-TRAP-MIB. In addition, extensions to RFC 1850 objects are described as defined in the two Cisco private MIBs, CISCO-OSPF-MIB and CISCO-OSPF-TRAP-MIB.

CISCO OSPF TRAP MIB

The cospfSetTrap MIB object represents trap events in CISCO-OSPF-TRAP-MIB. This is a bit map, where the first bit represents the first trap. The following MIB objects are TRAP events that have been added to support RFC 1850. To see a complete set of Cisco OSPF Trap MIB objects, see the CISCO-OSPF-TRAP-MIB file.

Table 4 shows the trap events described within the cospfSetTrap MIB object in the CISCO-TRAP-MIB:

Table 4 CISCO-OSPF Trap Events

CISCO-OSPF-TRAP-MIB Trap Events

Trap Event Description

cospfIfConfigError

This trap is generated for mismatched MTU parameter errors that occur when nonvirtual OSPF neighbors are forming adjacencies.

cospfVirtIfConfigError

This trap is generated for mismatched MTU parameter errors when virtual OSPF neighbors are forming adjacencies.

cospfTxRetransmit

This trap is generated in the case of opaque LSAs when packets are sent by a nonvirtual interface. An opaque link-state advertisement (LSA) is used in MPLS traffic engineering to distribute attributes such as capacity and topology of links in a network. The scope of this LSA can be confined to the local network (Type 9, Link-Local), OSPF area (Type 20, Area-Local), or autonomous system (Type 11, AS scope). The information in an opaque LSA can be used by an external application across the OSPF network.

cospfVirtIfTxRetransmit

This trap is generated in the case of opaque LSAs when packets are sent by a virtual interface.

cospfOriginateLsa

This trap is generated when a new opaque LSA is originated by the router when a topology change has occurred.

cospfMaxAgeLsa

The trap is generated in the case of opaque LSAs.

cospfNssaTranslatorStatusChange

The trap is generated if there is a change in the ability of a router to translate OSPF type-7 LSAs into OSPF type-5 LSAs.

For information about how to enable OSPF MIB traps, see the "How to Enable OSPF MIB Support of RFC 1850 and Latest Extensions" section.

Benefits of the OSPF MIB

The OSPF MIBs (OSPF-MIB and OSPF-TRAP-MIB) and Cisco private OSPF MIBs (CISCO-OSPF-MIB and CISCO-OSPF-TRAP-MIB) allow network managers to more effectively monitor the OSPF routing protocol through the addition of new table objects and trap notification objects that previously were not supported by the RFC 1253 OSPF MIB.

New CLI commands have been added to enable SNMP notifications for OSPF MIB support objects, Cisco-specific errors, retransmission and state-change traps. The SNMP notifications are provided for errors and other significant event information for the OSPF network.

How to Enable OSPF MIB Support of RFC 1850 and Latest Extensions

This section describes the configuration tasks for the OSPF MIB Support feature. Each task in the list is identified as either required or optional.

• Enabling OSPF MIB Support (required)

• Enabling Specific OSPF Traps (optional)

• Verifying OSPF MIB Traps on the Router (optional)

Enabling OSPF MIB Support

Perform this task to configure the SNMP server and enable the CISCO-OSPF-MIB and OSPF-MIB.

Prerequisites

Before the OSPF MIB Support of RFC 1850 and Latest Extensions feature can be used, the SNMP server for the router must be configured.

SUMMARY STEPS

1. enable

2. configure terminal

3. snmp-server community string1 ro

4. snmp-server community string2 rw

5. snmp-server host {hostname | ip-address} [vrf vrf-name] [traps | informs] [version {1 | 2c | 3 [auth | noauth | priv]}] community-string [udp-port port] [notification-type]

6. snmp-server enable traps ospf

7. end

DETAILED STEPS

Command or Action

Purpose

Step 1

enable
Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2

configure terminal
Example:

Router# configure terminal

Enters global configuration mode.

Step 3

snmp-server community string1 ro
Example:

Router(config)# snmp-server community public ro

Enables read access to all objects in the MIB, but does not allow access to the community strings.

Step 4

snmp-server community string2 rw
Example:

Router(config)# snmp-server community private rw

Enables read and write access to all objects in the MIB, but does not allow access to the community strings.

Step 5

snmp-server host {hostname | ip-address} [vrf vrf-name] [traps | informs] [version {1 | 2c | 3 [auth | noauth | priv]}] community-string [udp-port port] [notification-type]
Example:

Router(config)# snmp-server host 172.20.2.162 version 2c public ospf

Specifies a recipient (target host) for SNMP notification operations.

•If no notification-type is specified, all enabled notifications (traps or informs) will be sent to the specified host.

•If you want to send only the OSPF notifications to the specified host, you can use the optional ospf keyword as one of the notification-types. (See the example.) Entering the ospf keyword enables the ospfSetTrap trap control MIB object.

Step 6

snmp-server enable traps ospf
Example:

Router(config)# snmp-server enable traps ospf

An opaque link-state advertisement (LSA) is used in MPLS traffic engineering to distribute attributes such as capacity and topology of links in a network. The scope of this LSA can be confined to the local network (Type 9, Link-Local), OSPF area (Type 20, Area-Local), or Autonomous System (Type 11, AS scope). The information in an opaque LSA can be used by an external application across the OSPF network. To enable the cospfMaxAgeLsa trap, enter the snmp-server enable traps ospf cisco-specific lsa command with the lsa-maxage keyword. To enable the cospfOriginateLsa trap, enter the snmp-server enable traps ospf cisco-specific lsa command with the lsa-originate keyword. When you enter the snmp-server enable traps ospf cisco-specific lsa command without either keyword, both traps will be enabled.

Examples

The following example enables the router to send OSPF opaque LSA notifications to the host at the address myhost.cisco.com using the community string defined as public whenever new opaque LSAs are created:

Router(config)# snmp-server enable traps ospf cisco-specific lsa lsa-originate
Router(config)# snmp-server host myhost.cisco.com informs version 2c public

OSPF MIB Support of RFC 1850 and Latest Extensions feature introduces the capability for Simple Network Management Protocol (SNMP) monitoring on the Open Shortest Path First (OSPF) routing protocol. Users have an improved ability to constantly monitor the changing state of an OSPF network by use of MIB objects to gather information relating to protocol parameters and trap notification objects that can signal the occurrence of significant network events such as transition state changes. The protocol information collected by the OSPF MIB objects and trap objects can be used to derive statistics that will help monitor and improve overall network performance.

Any Internet Protocol (IP) addresses used in this document are not intended to be actual addresses. Any examples, command display output, and figures included in the document are shown for illustrative purposes only.

CISCO-OSPF-TRAP-MIB Trap Events	Trap Event Description
cospfIfConfigError	This trap is generated for mismatched MTU parameter errors that occur when nonvirtual OSPF neighbors are forming adjacencies.
cospfVirtIfConfigError	This trap is generated for mismatched MTU parameter errors when virtual OSPF neighbors are forming adjacencies.
cospfTxRetransmit	This trap is generated in the case of opaque LSAs when packets are sent by a nonvirtual interface. An opaque link-state advertisement (LSA) is used in MPLS traffic engineering to distribute attributes such as capacity and topology of links in a network. The scope of this LSA can be confined to the local network (Type 9, Link-Local), OSPF area (Type 20, Area-Local), or autonomous system (Type 11, AS scope). The information in an opaque LSA can be used by an external application across the OSPF network.
cospfVirtIfTxRetransmit	This trap is generated in the case of opaque LSAs when packets are sent by a virtual interface.
cospfOriginateLsa	This trap is generated when a new opaque LSA is originated by the router when a topology change has occurred.
cospfMaxAgeLsa	The trap is generated in the case of opaque LSAs.
cospfNssaTranslatorStatusChange	The trap is generated if there is a change in the ability of a router to translate OSPF type-7 LSAs into OSPF type-5 LSAs.

Step 5	snmp-server host {hostname \| ip-address} [vrf vrf-name] [traps \| informs] [version {1 \| 2c \| 3 [auth \| noauth \| priv]}] community-string [udp-port port] [notification-type] Example: Router(config)# snmp-server host 172.20.2.162 version 2c public ospf	Specifies a recipient (target host) for SNMP notification operations. •If no notification-type is specified, all enabled notifications (traps or informs) will be sent to the specified host. •If you want to send only the OSPF notifications to the specified host, you can use the optional ospf keyword as one of the notification-types. (See the example.) Entering the ospf keyword enables the ospfSetTrap trap control MIB object.
Step 6	snmp-server enable traps ospf Example: Router(config)# snmp-server enable traps ospf	Enables all SNMP notifications defined in the OSPF MIBs. Note This step is required only if you wish to enable all OSPF traps. When you enter the no snmp-server enable traps ospf command, all OSPF traps will be disabled.
Step 7	end Example: Router(config)# end	Ends your configuration session and exits global configuration mode.
