Add ICMP Path Echo operations to devices

ICMP Path Echo IP SLA operations measure round trip time between each node on a designated path on your network. Round trip time is measured hop-by-hop. These operations ensure that your network devices are operational and performing as expected.

  • To add ICMP Path Echo operations, you must add CLI login credentials to your source node. For more information, see Configure CLI credentials in SolarWinds VNQM.
  • You cannot add operations that have been previously created with SolarWinds VoIP and Network Quality Manager. If you have already created an operation with the same operation number, you must manually remove the operation from the device.
  1. Log in to your SolarWinds VoIP and Network Quality Manager server as an administrator.
  2. Click Settings > All Settings.
  3. Under Product Specific Settings, click VoIP & Network Quality (VNQM) Settings.
  4. Under Manage IP SLA Operations, click Add new operations.
  5. Select Create new operations, and click Next.
  6. Select ICMP Path Echo, and click Next.
  7. Select the type of path your network is configured to use. For more information, see Designate paths in SolarWinds VNQM.
  8. Select the source node you want to use for your ICMP Path Echo operation.

    If you do not see your IP SLA routers in the list, you must add the devices before you can continue. For more information, see Adding Devices for Monitoring in the Web Console.

  9. If the target node is being monitored, select it from the list.
  10. To create the path in only one direction, select No, create the path in just one direction.
  11. To specify an external node as a target, complete the following procedure.
    1. Click Yes, use external node as a target.
    2. Enter the IP address or host name of the external node you want to add.

      If you use a host name, the source node of the operation must be able to successfully resolve the host name.

  12. Click Next.
  13. Enter the frequency for the operation to be performed.
  14. Define the warning and critical threshold values.
  15. To assign a type of service (ToS) or Virtual Routing and Forwarding (VRF) name for this path, expand Advanced, and enter the type of service number and VRF name in the appropriate fields.

    • The ToS octet is a decimal value (0-255) that sets the precedence for VoIP traffic monitored with Cisco IP SLA operations. The default ToS value used by SolarWinds VoIP and Network Quality Manager is 184, corresponding to Expedited Forwarding (EF) per hop behavior (PHB) and a Differentiated Service Code Point (DSCP) value of 46. For more information about the ToS octet, see Setting Traffic Precedence.
    • VRFs only exist on provider edge routers (PE). A VRF is a routing and forwarding table instance, and you can have more than one VRF per PE. The VRF includes routes that are available to a certain set of sites. A VRF is named based on the VPNs it services and on the role of the CE in the topology.
  16. Click Next.
  17. To rename operations or edit any other operation properties, select the operations you want to modify, and click Edit.
  18. Review the operations you want to create, and click Create Operations.

    Depending on the number of operations that are being created, this process can take several minutes to.

  19. Click Go to VNQM Home to finish the procedure and return to the SolarWinds VoIP and Network Quality Manager home page.
