Configuring the path jitter operation

The path jitter operation measures the jitter, negative jitters, and positive jitters from the NQA client to
each hop on the path to the destination.
Before you configure the path jitter operation, perform the following configurations:
Enable sending ICMP time-exceeded packets on the intermediate devices between the source and
•
the destination devices. If the intermediate devices are HP devices, use the ip ttl-expires enable
command.
• Enable sending ICMP destination unreachable packets on the destination device. If the destination
device is an HP device, use the ip unreachables enable command.
For more information about the ip ttl-expires enable and the ip unreachable enable command, see Layer
3—IP Services Command Reference.
