What happens if you try to run tcpdump on the tr0 or lo0 interfaces?

If that doesn't work either, then the problem is probably that your OS
(which, from the "Austin/IBM" part of your e-mail address, I infer is
probably AIX) doesn't support capturing packets on the tr0 or lo0
interfaces.

If that does work, then I'd try building tcpdump from source, and make
sure it's linked with the *exact same version of libpcap* with which
tcpdump is linked.  If the resulting tcpdump doesn't work, then the
problem is probably that the version of libpcap in question can't manage
to support capturing packets on the tr0 or lo0 interfaces.
