For the path jitter operation, the first four bytes of the payload of an ICMP echo request are for
special purpose. The string fills the remaining part of payload.
Examples
# Specify abcd as the payload fill string for ICMP echo requests.
<Sysname> system-view
[Sysname] nqa entry admin test
[Sysname-nqa-admin-test] type icmp-echo
[Sysname-nqa-admin-test-icmp-echo] data-fill abcd
# In TCP template view, specify abcd as the payload fill string for probe packets.
<Sysname> system-view
[Sysname] nqa template tcp tcptplt
[Sysname-nqatplt-tcp-tcptplt] data-fill abcd
