I used the following script to poll some snmp variables and put the
values in the ping payload. Then send the ping towards a host so that it
will pass the place you put your wireshark-system :-)
========== <script> ==========
#!/bin/bash
cnt=`snmpget -OQv -v 2c -c DCSML-ON 172.23.19.104 .1.3.6.1.4.1.1872.2.5.1.2.4.2.1.12.2`
cpu=`snmpget -OQv -v 2c -c DCSML-ON 172.23.19.104 .1.3.6.1.4.1.1872.2.5.1.2.2.2.0`

str=`printf "[%07d|%03d|%02d]" $cnt $cpu $fdb`

ping -c1 -p $hex 172.23.108.2 >/tmp/monping.log

Output in (wire|t)shark is like this:

Maybe it's an idea :-)
