SNMP Trap Receiver tool

SNMP traps are network health notifications sent on UDP port 162. The SNMP Trap Receiver tool in ETS for the Desktop receives and displays SNMP traps sent from any of the following:

  • Network management applications
  • Network devices
  • Servers

You can use SNMP Trap Receiver to analyze the format of the trap and to verify that a trap source is configured and functioning properly.

The SNMP Trap Receiver adds a powerful diagnostic tool to your kit. Trap Receiver ensures your network management solutions are properly configured to accept traps sent by your devices. The format of the trap is dictated by the device sending the trap. For more assistance with interpreting the Trap Details, refer to the documentation for the device sending the traps.

After you have launched the SNMP Trap Receiver, you are ready to start receiving and displaying traps. No configuration changes need to be made in order for the application to begin collecting traps.

Open the SNMP Trap Receiver tool

  • To launch the tool from the Toolset Launch Pad, locate the SNMP Trap Receiver tool and click Launch.

  • You can add the tool to a tab in the Workspace Studio, and access it from there.

  • To launch the tool from the Windows Start menu:

    1. Click Start > All > SolarWinds Engineer's Toolset.

    2. Right-click SNMP Trap Receiver, click More, and click Run as administrator.

Modify SNMP Trap Receiver settings

You can do the following with Trap Receiver settings:

  • Decode or show the raw data of trap OIDs.
  • Filter from what IP addresses, subnets, or address ranges you accept traps.
  • Filter what SNMP community strings to accept.
  • Log traps to a file.

To set SNMP Trap Receiver settings:

  1. Click File > Settings.

  2. Click the General tab, and then specify to decode trap OIDs.

    If you are analyzing a trap to ensure capture by your network management solution, you should view results both ways. Not all network solutions decode trap OIDs. This setting is applied to traps received after it is configured.

  3. Click the Device Filter tab, and then add the addresses to accept.

  4. Click the Community Filter tab, and then add the community strings from which to accept traps.

  5. Click the Logging tab, and then provide the path and name for your log file.

  6. Click OK.
