Is usage of Cisco-AVPair, or other similar variables, common enough to
include code for it? For example, perhaps they could be accessed via a
Perl hash-like structure as %{Cisco-AVPair[ssid]} to get "TEST" from
Cisco-AVPair = "ssid=TEST". I don't think the coe would be hard to
write, but I have no idea where it would fit in.

Oddly, I can do that. It works fine and I can reference the variables
later as ${SSID} and ${Pairs}. I was hoping that I could use unlang
constructs in the linelog config file but it sounds like that isn't the
case. I can live with just dumping %{Cisco-AVPair[*]} into my logs, I
just end up with some extra junk I don't care about. I've never been
100% clear on where I can and can't use unlang syntax. Thanks for the help,
