UDP Echo IP SLA operations measure round trip time between nodes on your network. These operations ensure that your network devices are operational and performing as expected.
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.
