Configuring a UDP jitter operation

CAUTION:
Do not perform a UDP jitter operation to well-known ports from 1 to 1023. Otherwise, the UDP jitter
operation might fail or the service on the well-known port might become unavailable.
Jitter means inter-packet delay variance. A UDP jitter operation measures unidirectional and
bidirectional jitters so that you can verify whether the network can carry jitter-sensitive services such
as real-time voice and video services.
A UDP jitter operation works as follows:
1. The NQA client sends UDP packets to the destination port at a regular interval.
2. The destination device puts a time stamp on each packet that it receives, and then it sends the
packet back to the NQA client.
3. Upon receiving the responses, the NQA client calculates the jitter according to the time stamps.
Configuration guidelines
•
The UDP jitter operation requires both the NQA server and the NQA client. Before you perform
the UDP jitter operation, configure the UDP listening service on the NQA server. For more
information about UDP listening service configuration, see
•
The display nqa history command does not show the results of the UDP jitter operation. Use
the display nqa result command to view the results, or use the display nqa statistics
command to view the statistics of the operation.
Configuration procedure
