UDP jitter operation configuration example
Network requirements
As shown in Figure 46, configure a UDP jitter operation to test the jitter, delay, and round-trip time
between Device A and Device B.
Figure 46 Network diagram
Configuration procedure
1. Assign each interface an IP address. (Details not shown.)
2. Configure static routes or a routing protocol to make sure the devices can reach each other.
(Details not shown.)
3. Configure Device B:
