Hi,
we have problem with provisioning SA EPC2302 modem. We use docsis_server as dhcp/tftp solution, and everything works with Motorola SBV5121E.
Problem occurs when we try initial communication with dhcp server. DHCP offers first IP and modem requests that addres from server but server than claim that adress is bad and offers another address. After that modem accept second IP but cannot doasn't proceed with MTA part. Also from cmts we cannot ping that modem trough IP.
I've included wireshark capture, dhcp config and logg (remove .txt part).

Has someone had similar problem, or any idea how to solve this. Also now and than modem gets good IP and starts provisoning MTA part.
All ideas are welcomed.
Thank you
Looking at The PCAP looks like you have the DHCP well covered, not sure what to tell you, I could not find any info on this model of modem since cisco took over things, but if it is really old or has really old firmware it may be wanting option 177 instead of 122 (this was the option CableLabs was using prior to option 122) anyways it could not hurt to send both option 122 and 177 fully populated.
