You can change payloads to attempt to force certain dataconditions on the
line. For example, a you may wish to prove the line encodingon your T1/E1
so by sending a pattern of all 0's it stresses the line encoding and timing
recovery of the link. This is a basic data pattern test (better suited to
dedicated test equipment) to isolate problem areas. I personally have never
played with payload contents as strictly speaking a ping is a simple
reachability test - but thats not to say you cannot use it to stress test
etc... You may want to trigger a capture on a data analyser using a certain
datapattern that you set in the ping payload.
Try searching www.cisco.com for more information on extended ping command
options.
