The slow upload speed when ODI DFP-34X-2C2 in 2.5Gb mode, this is known issue in some ISP where ISP using another Realtek ONU beside RTL960x

Mikrotik

Many Mikrotik device such as RB5009 flooding the GPON with 2.5Gb links meanwhile GPON upload is 1.25Gb, many packet are flooded and late discarded, to solve this try follow this tweak Luckygecko1 @ Reddit

Fixes

You may try these

OMCI_TM_OPT

flash set OMCI_TM_OPT 0
reboot
  1. Priority controlled
  2. Rate controlled
  3. Priority and rate controlled

diag

/bin/diag bandwidth set egress port all rate 4194296
/bin/diag bandwidth set ingress port all rate 4194296
  • these will not survive across reboot!

If these wont fix the issue, you can't use ODI DFP-34X-2C2, unless ODI fix the firmware.
