This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests.

This command enables or disables Repeater MIB notifications, as defined in RFC 1516. RFC 1516 defines objects for managing IEEE 802.3 10 Mbps baseband repeaters, also known as hubs.

Two sets of notifications are available for this command. The following notification is defined in the CISCO-REPEATER-MIB (enterprise 1.3.6.1.4.1.9.9.22.3):

  • 1 ciscoRptrIllegalSrcAddrTrap (illegal source address trap)

The following notifications are defined in the CISCO-REPEATER-MIB-V1SMI (enterprise 1.3.6.1.2.1.22):

  • 1 rptrHealth

  • 2 rptrGroupChange

  • 3 rptrResetEvent

For a complete description of the repeater notifications and additional MIB functions, refer to the CISCO-REPEATER-MIB.my and CISCO-REPEATER-MIB-V1SMI.my files, available on Cisco.com at

http://www.cisco.com/public/mibs/ .

When the optional health keyword is used, the rptrHealth trap is sent when the value of rptrOperStatus changes, or upon completion of a nondisruptive test.

The rptrOperStatus object indicates the operational state of the repeater. Status values are as follows:

  • other(1)--undefined or unknown status

  • ok(2)--no known failures

  • rptrFailure(3)--repeater-related failure

  • groupFailure(4)--group-related failure

  • portFailure(5)--port-related failure

  • generalFailure(6)--failure, unspecified type

When the optional reset keyword is used, the rptrResetEvent trap is not sent when the agent restarts and sends an SNMP coldStart or warmStart trap.

The snmp-server enable traps repeatercommand is used in conjunction with the snmp-server hostcommand. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send SNMP notifications, you must configure at least one snmp-server hostcommand.

Examples

12.2(33)SXH

This command was integrated into Cisco IOS Release 12.2(33)SXH.

Usage Guidelines

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests for the specified notification types.

If you do not enter an snmp-server enable traps snmpcommand, no notifications controlled by this command are sent. To configure the router to send these SNMP notifications, you must enter at least one snmp-server enable traps snmpcommand. When you enter the command with no keywords, all notification types are enabled. When you enter the command with a keyword, only the types of notifications related to that keyword are enabled.

When you use the optional authenticationkeyword, the authenticationFailure(4) trap signifies that the sending device is the addressee of a protocol message that is not properly authenticated. The authentication method depends on the version of SNMP being used. For SNMPv1 or SNMPv2c, authentication failure occurs for packets with an incorrect community string and the SNMP traps are generated. For SNMPv3, authentication failure occurs for packets with an incorrect SHA/MD5 authentication key or for a packet that is outside the authoritative SNMP engine’s window (for example, packets that are configured outside access lists or time ranges) and a report PDU is generated, however authentication failure traps are not generated.

When you use the optional linkupkeyword, the linkUp(3) trap signifies that the sending device recognizes one of the communication links represented in the agent’s configuration coming up.

When you use the optional linkdownkeyword, the linkDown(2) trap signifies that the sending device recognizes a failure in one of the communication links represented in the agent’s configuration.

The snmp-server enable traps snmp [linkup] [linkdown] form of this command globally enables or disables SNMP linkUp and linkDown traps. After enabling either of these traps globally, you can disable them on specific interfaces using the no snmp trap link-status command in interface configuration mode. On the interface level, linkUp and linkDown traps are enabled by default, which means that these notifications do not have to be enabled on a per-interface basis. However, linkUp and linkDown notifications will not be sent unless you enable them globally using the snmp-server enable traps snmp command.

When you use the optional coldstartkeyword, the coldStart(0) trap signifies that the sending device is reinitializing itself such that the agent’s configuration or the protocol entity implementation may be altered.

When you use the optional warmstartkeyword, the warmStart(1) trap signifies that the sending device is reinitializing itself such that neither the agent configuration nor the protocol entity implementation is altered.

The snmp-server enable traps snmpcommand is used in conjunction with the snmp-server hostcommand. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. In order to send notifications, you must configure at least one snmp-server hostcommand.

For a host to receive a notification controlled by this command, you must enable both the snmp-server enable traps command and the snmp-server hostcommand for that host. If the notification type is not controlled by this command, you must enable the appropriate snmp-server host command only.

Examples

The following example shows how to enable the router to send all traps to the host myhost.cisco.com, using the community string public:

Router(config)# snmp-server enable traps snmp
Router(config)# snmp-server host myhost.cisco.com public snmp

The following example shows how to enable the router to send all inform notifications to the host myhost.cisco.com using the community string public:

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

The following example shows how to enable all SNMP trap types, and then disable only the linkUp and linkDown traps:

Router> enable
Router# configure terminal
Router(config)# snmp-server enable traps snmp
Router(config)# end
Router# more system:running-config | include traps snmp
snmp-server enable traps snmp authentication linkup linkdown coldstart warmstart
Router# configure terminal
Router(config)# no snmp-server enable traps snmp linkup linkdown

Modification

12.2(13)T

This command was introduced to support DPT-OC12 Port Adapters.

Usage Guidelines

The Cisco SRP MIB module (CISCO-SRP-MIB.my) provides objects for monitoring IP-over-SONET IPS SRP traffic using the SNMP. When IPS is enabled, if a node or fiber facility failure is detected, traffic going toward or coming from the failure direction is wrapped (looped) back to go in opposite direction on the other ring.

The snmp-server enable traps srp command enables SRP state change notifications (traps or informs). SRP state change notifications are generated whenever one of the two sides of an SRP interface ring enters or leaves the wrapped state (when a ring wraps, or when a ring is restored).

Specifically, the srpMACIpsWrapCounter object in the CISCO-SRP-MIB increments when a Ring wraps, and the value of the rpMACIpsLastUnWrapTimeStamp object changes when a ring unwraps. (An “unwrap” event happens when the original ring is restored.)

The snmp-server enable traps srp command is used in conjunction with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send SNMP notifications, you must configure at least one snmp-server host command.

Examples

In the following example, SRP-specific informs are enabled and will be sent to the host “myhost.cisco.com” using the community string defined as public:

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

12.2SX

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests.

This command controls (enables or disables) system logging message notifications. System logging messages (also called system error messages, or syslog messages) are status notification messages that are generated by the routing device during operation. These messages are typically logged to a destination (such as the terminal screen, to a system buffer, or to a remote “syslog” host).

If your software image supports the Cisco Syslog MIB, these messages can also be sent via SNMP to a network management station (NMS). To determine which software images support the Cisco Syslog MIB, used the Cisco MIB Locator tool at http://www.cisco.com/go/mibs/ .(At the time of writing, the Cisco Syslog MIB is only supported in “Enterprise” images.)

Unlike other logging processes on the system, debug messages (enabled using CLI debug commands) are not included with the logging messages sent via SNMP.

To specify the severity level at which notifications should be generated, use the logging history global configuration command. For additional information about the system logging process and severity levels, see the description of the logging commands.

The syslog notification is defined by the clogMessageGenerated NOTIFICATION-TYPE object in the Cisco Syslog MIB (CISCO-SYSLOG-MIB.my). When a syslog message is generated by the device a clogMessageGenerated notification is sent to the designated NMS. The clogMessageGenerated notification includes the following objects: clogHistFacility, clogHistSeverity, clogHistMsgName, clogHistMsgText, clogHistTimestamp.

For a complete description of these objects and additional MIB information, see the text of CISCO-SYSLOG-MIB.my, available on Cisco.com using the SNMP Object Navigator tool at http://www.cisco.com/go/mibs . See also the CISCO-SYSLOG-EXT-MIB and the CISCO-SYSLOG-EVENT-EXT-MIB.

The snmp-server enable traps syslogcommand is used in conjunction with the snmp-server hostcommand. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send SNMP notifications, you must configure at least one snmp-server host command.

Examples

The following example enables the router to send system logging messages at severity levels 0 (emergencies) through 2 (critical) to the host at the address myhost.cisco.com using the community string defined as public:

Router(config)# snmp-server enable traps syslog
 
Router(config)# logging history 2

snmp-server enable traps vswitch dual-active

To enable the CISCO-VIRTUAL-SWITCH-MIB Simple Network Management Protocol (SNMP) notification (trap) when the dual-active state is detected, use the snmp-server enable traps vswitch dual-active command in global configuration mode. To disable the CISCO-VIRTUAL-SWITCH-MIB SNMP notification (trap), use the no form of this command.

Command History

Release

Modification

15.1(1)SY

This command was introduced.

Usage Guidelines

The virtual switch link (VSL) is a special link that carries control and data traffic between the two chassis of a virtual switching system (VSS). The VSL is implemented as an EtherChannel with up to eight links. The VSL gives control traffic higher priority than data traffic so that control messages are never discarded. The SNMP agent runs on the VSS active supervisor engine. CISCO-VIRTUAL-SWITCH-MIB is the MIB for virtual switch mode.

If the VSL fails, the VSS standby chassis cannot determine the state of the VSS active chassis. To ensure that switchover occurs without delay, the VSS standby chassis assumes that the VSS active chassis has failed and initiates switchover to take over the VSS active role.

If the original VSS active chassis is still operational, both chassis are now VSS active. This situation is called a dual-active scenario. A dual-active scenario can have adverse effects on network stability because both chassis use the same IP addresses, Secure Shell (SSH) keys, and Spanning Tree Protocol (STP) bridge ID. The VSS must detect a dual-active scenario and take recovery action.

The snmp-server enable traps vswitch dual-active command enables the dual-active state change notification. When the VSS changes state to dual-active, SNMP sends the cvsDualActiveDetectionNotif notification. To receive this message from SNMP, enable this command.

This command enables both trap and inform requests.

Examples

The following example shows how to enable the cvsDualActiveDetectionNotif notification:

Device(config)# snmp-server enable traps vswitch dual-active
Device(config)# exit
Device# test snmp trap vswitch dual-active

cvsDualActiveDetectionNotif notification was sent.
Device# show running-config all

.
.
.
snmp-server enable traps vswitch dual-active

.
.

The following example shows how to disable the cvsDualActiveDetectionNotif notification:

Device(config)# no snmp-server enable traps vswitch dual-active
Device(config)# exit
Device# test snmp trap vswitch dual-active

cvsDualActiveDetectionNotif notification is disabled.
