Path jitter operation configuration example
Network requirements
As shown in Figure 49 , configure a path jitter operation to test the round trip time and jitters from Device
A to Device B and Device C.
Figure 49 Network diagram
Configuration procedure
# Assign each interface an IP address. (Details not shown.)
# Configure static routes or a routing protocol to make sure the devices can reach each other. (Details not
shown.)
# Use the ip ttl-expires enable command on Device B and use the ip unreachables enable command on
Device C.
# Create a path jitter operation and specify 10.2.2.2 as the destination IP address.
