What kind of authentication does Excitel use for ONTs?

@MrGordon You might need to clone MAC address too like Jio. It seems like Airtel has different parameters for different areas. You also might need correct VLAN.

@MrGordon Did you try changing VLAN id? For eg, in TP-Link model i had to give 950 as VLAN, but in others it is 100.

Check this thread also, Indian ISP Airtel: Working Configurations · Issue #127 · Anime4000/RTL960x

Someone mentioned about setting 2271 as VLAN in his ODI SFP stick.

@MrGordon Are you able to make SFP to work with Airtel? PLOAM not needed for Airtel, its just working fine with GPON SN itself. Got myself ODI DFP-34X-2C2 model and made it work with Mikrotik.

@hariselio I couldn't spend much time on this after this. I get a feeling that the firmware of the ZyXEL unit that I have, is not respecting changes to the GPON SN. In the UI it shows that the serial has changed, but in reality it doesn't seem to be changed.

When I tried on BSNL, it got stuck in O2/O3 state ie serial number verification stage. In case of Airtel, it went to O5, but I think AIrtel does fake O5. I intended to flash a newer firmware, and see if it helps, but didn't get time for it.

The other Huawei GPON SFP I got, need serial console access to root it and enable telnet/shell.

How much was the ODI DFP-34X-2C2 including delivery, where did you get it from? I had reached out to a reseller of DFP-34X-2C2, said it is some 28 USD/unit (before shipping/customs).

@MrGordon I got it shipped to US and my friend got it today. It was from AliExpress and costed me 52$.

Regarding Fake O5, i guess its mostly due to VLAN ID difference, At least this was my experience based on TP-Link one and this SFP. Each ONU handles VLAN ID differently, whatever airtel provided one has 100, TP-Link had 950 and this SFP works with 980. All in same connection.

 

[MrGordon]

@hariselio I see, that is interesting. In my case, on Airtel, I currently use a Huawei HG8120C ONT, in that VLAN 100 works.

But what is surprising is that, why it didn't work on BSNL (run by an LCO) and getting stuck at O2/O3 which means failing at serial number check. Anyway I will spend some time this week if possible and see if I can make any progress.

 

[hariselio]

I was also using HG8120C with VID 100, Airtel gave me Dasan 680 model and that also works with 100.

 

[MrGordon]

How did you find the correct VLAN for the SFP module in this case?

 

[hariselio]

Once you get telnet access, execute omcicli command.

Try any one of the below three commands, At least one should show.

omcicli mib get 84

omcicli mib get 171
