You're doing exactly what I would do.
The renewal is unicast, so if you can the ONT from the DHCP server then
the unit should be able to renew. My guess would be something in the
middle either dropping the request from the client or dropping the ack
from the server. Maybe a misbehaving switch or misconfigured firewall
rule. Wireshark and/or logs on one end or the other might tell you
which step is not happening, but they won't tell you which device is
dropping the ball. I'm guessing you'll run wireshark, see a missing
packet from somebody and then have to packet capture at points in
between to see if the missing packet is present or not at that point.

Subject: [AFMUG] Need help with DHCP problem
I have not dug into the entrails of DHCP since NAT was added to Canopy,
so long time ago. I have Calix ONTs that are going away when their
DHCP reservations expire. They normally get them from DHCPatriot.
People lose service, they call, we reset the ONT and service comes
back.
Started a couple of days ago, no network changes to speak of. But
about 30% are having the problem.
There is no way the DHCPatriot could be causing this is there? Once it
hands out an IP and a reservation time, it is out of the loop, right?
I suggest setting up an ONT with a reservation time of 1 hour then
wireshark the DHCPatriot to see of the ONT ever comes knocking, or if
it does, what is going on between those two.
Any other troubleshooting ideas out there? Going to bed, hopefully
there will be a bunch of brilliant posts in the morning leading us
directly to the bad actor.
