- num-packets
: number of UDP packets in each sequence.
- interval
: time interval between packets in a sequence.
You can define
‘
udp-jitter
’
command parameters only at the time of operation creation; you
will not be able to edit them later. To define other parameters, remove the existing
operation and create a new one.
ICMP Echo operation configuration mode commands
Command line request in UDP Jitter operation configuration mode appears as follows:
console(config-ip-sla-udp-jitter)#
Table 5.189 —ICMP Echo operation configuration mode commands

For normal execution of UDP Jitter operation, you should set the operation time
parameters taking into account the following expression:
frequency
>
(interval
* (num-packets – 1))
+
timeout
