I tried Hariselios config letter to letter, as well as
GPON SN and all the other fields I could put in onu_sn.htm
With that, and without just via GponSN. And other combinations in onu_sn.htm
Yesterday evening I tried it on my neighbours connection as well, same fatbox/OLT, but some Dragonedge
ONT.
Didnt work, Vlan scan just fails everytime. Both with G3 V1 & V2.
Without Vlan Scan just tagging it 100, both on G3 and AX12 too, didn't work.
What I can guess in my limited experience is, G3 does not have enough tweakables, like Sw1/Sw2 to make it work with the notorious ALCL OLT. I think it doesn't have telnet support as well to run Vlan Search commands.
Or maybe Airtel has some special sauce in their configs in the backend.
In any case, G3V1 or even V2 isn't a foolproof working solution as per my experience.
I am in talks with BSNL as they provide Static IP and I know the LCO around here.
