The Traps Sent with SNMP-Server Enabled Traps Configured

Document ID: 45362

Updated: Oct 26, 2005



This document describes the traps sent when you configure the command snmp-server enable traps <> on a Cisco device.



Readers of this document should have knowledge of these topics:

  • How to configure SNMP on a Cisco device

  • Use of SNMP get and walk commands

Components Used

This document applies to Cisco devices (routers and switches) that run IOS which supports SNMP. The information in this document is based on several releases of IOS® because the trap command differs from release to release and platform to platform. For example, you will not have the capacity to send ATM related traps on a system that has no ATM interface.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.


Refer to Cisco Technical Tips Conventions for more information on document conventions.

An Overview of the Traps Enabled on Your Device

In order to get an overview of the traps you have enabled on your device, issue this command on every Cisco IOS device:

cognac# conf t

Enter configuration commands, one per line.  End with CNTL/Z.

cognac(config)# snmp-server enable traps ?

  atm          Enable SNMP atm traps

  bgp          Enable BGP state change traps

  config       Enable SNMP config traps

  dial         Enable SNMP dial control traps

  dlsw         Enable SNMP dlsw traps

  dsp          Enable SNMP dsp traps

  entity       Enable SNMP entity traps

  envmon       Enable SNMP environmental monitor traps

  frame-relay  Enable SNMP frame-relay traps

  hsrp         Enable SNMP HSRP traps

  ipmulticast  Enable SNMP ipmulticast traps

  isdn         Enable SNMP isdn traps

  msdp         Enable SNMP MSDP traps

  rsvp         Enable RSVP flow change traps

  rtr          Enable SNMP Response Time Reporter traps

  snmp         Enable SNMP traps

  syslog       Enable SNMP syslog traps

  tty          Enable TCP connection traps

  voice        Enable SNMP voice traps

  xgcp         Enable XGCP protocol traps


Once you know the traps you have enabled, you can enable them as you need. This document helps you find which traps are sent when you enable a command.

Note:  This list can differ from platform to platform and release to release because of the features in a specific device and available interfaces.
