I am using a VSOL EPON OLT with some third-party Huawei ONUs (HG8145C, 346M, 546M series) and trying to remotely push TR-069/WAN configuration to them (for bulk customer onboarding). What i’ve tried: ✅ onu ctc fast\_leave — works ❌ onu pri tr069\_mng — Time Out ❌ onu ctc mgmt ip — VarNoResource ❌ profile srv + tr069\_mng bind — accepted in config, but never actually applied to the ONU VSOL’s own support team confirmed: "TR-069 configuration parameters on Huawei ONUs rely on proprietary OMCI messages. VSOL OLT cannot configure Huawei ONU via private OMCI." Questions: 1. Has anyone successfully pushed TR-069 to a Huawei ONU on a VSOL EPON OLT? How? 2. Has anyone tried DHCP Option 43 (ONU-side auto-discovery) with this exact combination? 3. Is switching to a Huawei GPON OLT (instead of VSOL) the real fix here? 1. Currently i have tested wifi user name, password change , wifi on off and device reboot Is another parameters that we can do other than these ---

I’m pretty sur I used ACS Discovery (DHCP Option 43) with Huawei ONU several years ago and it was working fine. You just need to figure out the good syntax for your DHCP server. I didn’t do it with a V-SOL OLT but the OLT don’t matter once WANs are created and can communicate through the OLT.
