I've never used wireshark; I only know conceptually the kinds of things it can do; so if you need specific help in this area, someone else will have to help you.
Wireshark (and tshark, it's CLI brother) is really handy about decoding packets into human-readable form. Combine that with "grep -iv" to filter out what you don't want to see.
My concern is that, since the upstream dhcpd sends the lease info at the moment of negotiation, you'd need to start tshark *before* pon and I don't know if tshark will see the new interface and start capturing on it.
