Thanks, Simon<br>
<br>
I now have the prefix string printed.. So that's good, but no matter
what I seem to put for the substring offset, there's nothing further
printed. I'm scratching my head because I can see the text in the
package and I just wish there was an easier way to extract it.<br>
<br>
Here's the raw:<br>

Here it is in wireshark:(snip)<br>
I've tried substring(8,7) which seems like it should work, but many
other possibilitie as well.<br>
maybe I should build up a custom option with 2 32 bit ints in the
front to try to force it with a suboption? It doesn't seem like it
should be this difficult.<br>

The only lines that output anything are the 'hw' line at the beginning and the plain old option125 at the end. The other 2 lines output nothing, not even the plain text.. I wish there was extra levels of debugging that I could turn on to see raw options processing.

Try changing "substring(option125,1,7)" to "pick-first-value(substring(option125,1,7),"")" and see what happens (check the man page to make sure I've got that right). Ditto for client-id.
With concat, if any element is null, then the whole result is null, and so log won't log anything.
