Looking through the documentation for ip sla udp jitter, Cisco says these are the default values -
"By default, ten packet frames (N), each with a payload size of 10 bytes (S), are generated every 10 ms (T), and the operation is repeated every 60 seconds (F)."
however, looking at sh ip sla configuration on my router I get different values -
*******************************************************************
ip sla 1001
udp-jitter 2.2.2.2 20000 source-ip 1.1.1.1
ip sla schedule 1001 life 3000 start-time now
sh ip sla configuration
Entry number: 1001
Owner:
Tag:
Operation timeout (milliseconds): 5000
Type of operation to perform: udp-jitter
Target address/Source address: 1.1.1.1/2.2.2.2
Target port/Source port: 20000/0
Type Of Service parameter: 0x0
Request size (ARR data portion): 32
Packet Interval (milliseconds)/Number of packets: 20/10
**********************************************************************
This is confusing to me. According to this, the operation is sending 10 frames, at 32 bytes each with 20 ms between frames. Is this correct? Or are these default parameters for UDP Jitter? If so, this definitely does not match up with the data presented on cisco.com

Hi Alex,
Thanks for sharing the Doc ..
As per my understanding ,this is given just as an example or could be a documentaion Bug because if you look at the table 1 , you will see what is true.
I have highlighted it in the Image attached.

Hi Alex ,
for UDP-jitter , Request Data size is :32( By Default) ,however you can change it .
NMS-6500(config-ip-sla-jitter)#request-data-size ?
<16-1500> Number of bytes in payload
for ICMP ECHO ,
Request Data size is :28 ( By Default)
Thanks-

Afroz - appreciate the reply. So my test operation would end up being
ten packet frames (N), each with a payload size of 32 bytes (S), are generated every 20 ms (T), and the operation is repeated every 60 seconds (F).
this is quite different than what the documentation says.

this is the link Afroz - http://www.cisco.com/en/US/docs/ios-xml/ios/ipsla/configuration/15-s/sla_udp_jitter.html
The wording I referenced is right above Table 1
