VNQM Getting Started Home

An IP SLA operation is a test that SolarWinds VNQM performs between a source and a target Cisco device on your network. The results of an operation help you measure quality of service and identify root causes when network performance levels drop. SolarWinds VNQM supports a number of IP SLA operations, including DHCP, DNS, and FTP. For more information on supported operations, see What is IP SLA monitoring?

You can either manually add IP SLA operations to SolarWinds VNQM, or if you have IP SLA operations already defined on your device, you can automatically add them to SolarWinds VNQM. For instructions on automatically adding operations to SolarWinds VNQM, see Add existing operations to SolarWinds VNQM.

The following example shows you how to manually add a VoIP UDP Jitter operation to SolarWinds VNQM. VoIP UDP Jitter operations measure call path metrics on your VoIP network. These operations ensure that your VoIP network is operational and performing as expected. The network segment in the example is defined between the dev_ottawa_2621 source router and a target external IP address.

There is a known issue that prevents you from using SolarWinds VNQM to create operations on Cisco devices using IOS 15.3 and later. See Unable to add operations to VNQM for a workaround to this problem.

The majority of operations use SNMP to poll. Path-based operations use CLI.

  1. Log in to SolarWinds VNQM as an administrator.
  2. Click Settings > All Settings > VoIP & Quality Settings.
  3. In the Manage IP SLA Operations section, click Add new operations.


  4. Select Create new operations, and click Next.


  5. Select VoIP UDP Jitter, and click Next.


  6. On the Define Paths panel, click Simple, and click Next.

    You can select other path types. See the SolarWinds VNQM Administrator Guide for more information on path types.

  7. Select the source nodes you want to add to the VoIP UDP Jitter operation, and click Next.

    In this example, the source node is dev_ottawa_2621.


  8. Select the target nodes you want to add to the VoIP UDP Jitter operation.
  9. To create the path in only one direction, select No, create the path in just one direction.

    When you create a path in each direction, SolarWinds VNQM deploys the operation to the target device, which becomes the source of the second leg of the operation.

  10. To specify an external node as a target, click Yes, use external node as a target.

    You can also target a node that you have added to SolarWinds VNQM.

  11. Enter the IP address or host name of the external node you want to add, and click Next.


  12. Enter the frequency for the operation to be performed.

    SolarWinds recommends you accept the default frequency.

  13. Define your warning, critical, and maximum threshold values.

    SolarWinds recommends you accept the default thresholds.


  14. Click Advanced and in the CODEC field, select GSM 711 ULAW.

    The Advanced options correspond to the type of operation you are creating. GSM 711 ULAW is the most common CODEC for VoIP UDP Jitter operations.


  15. Click Next.
  16. Select the operation you want to create, and click Create Operations.

    Depending on the number of operations you create, this process can take several minutes.

  17. Click Go to VNQM Home and review the All IP SLA Operations resource.

    It can take several minutes for the resource to populate with data. When the status icon turns green, SolarWinds VNQM is monitoring the operation.
