ONT DHCP connection issue

Help and support
1

I’m writing this post out of sheer frustration, I’ve tried Yayzi Whatsapp message, Discord group and raised a ticket – this ticket was subsequently closed.

I had Yayzi 2.3Gbps installed since September 2024 and the ONT is connected to a self build Pfsense ‘bare-metal’ server where the WAN is connected to an Intel X550-T2 10Gbps NIC. I’ve set a flag within Pfsense to force the X550 to 2.5Gbps within a VLAN set to 911 and the WAN was set at this VLAN. In the September installation, this worked with >2Gbps up/down speeds.

On Saturday (30th Nov), the ONT was power cycled and on powering back on it did not connect to the CityFibre (CF) DHCP server. Since yesterday (2nd Dec) I can see the ONT was assigned an IP address (154.56 range) several times and the internet has come on intermittently for a few minutes at a time. However, this connection doesn’t seem persistent, and I’ve been assigned at least 2 IPs (that I’ve noticed). When it is assigned an IP, the ONT will only handshake with the X550 at 1Gbps. When I send the command to force the X550 to 2.5Gpbs [sysctl dev.ix.2.advertise_speed=55] the NIC will show as being up, i.e. connected to the ONT but the connection to the CF DHCP server will then go down, and I’ll lose internet connection again. Even though I have the [sysctl dev.ix.2.advertise_speed=55] in the System Tunables table (meaning it the NIC should be set to 2.5Gbps on boot), if I reboot the Pfsense server then initially the X550 will connect with an IP to the VLAN but at 1Gbps. If I send the manual command to set the NIC back to 2.5Gbps then the CF DHCP connection is again dropped, and this time does not return.

Prior to Saturday, this setup was working (except for the poor lag on 156.54 and not connecting to certain domains, but these are separate issues). Right now, I do not have a working internet connection. Can you please update be on 1) what’s causing this issue? 2) ETA to get this working again? and 3) is there an interim solution to getting an internet connection if there is no reasonable ETA?

Regards

Marc

If you leave the card set to 1gb/s Link speed does the connection stay up?

I’m not a PF sense wizard, But you shouldn’t have to force the cars to run it 2.5 GB. It should auto negotiate the link speed with the ONT as the maximum link speed it can provide is 2.5 GB depending on which ONT you have

If you got a black box with four lights on it called a Calix G1000 (I think) That will max out at 2.5 GB/ second

If you were super lucky and got a Nokia white box, it will come out at 10 GB/s

Also have you sent logs from PFsense to Yayzi?

If the card is set to 1Gbps and when the ONT has an assigned IP then the connection stays up sometimes on say a reboot. Other times it goes down again and then doesn’t return. The ONT is the Calix G1100X (i think) and all lights are green regardless of what’s going on with the DHCP assignment.

Regarding the ONT, what it seems to be doing is cycling the connection to the X550. Initially it will connect at 1Gbps, but I can get it to connect at 2.5Gbps using the command shown above. However, since it doesn’t have a connection to the DHCP server it cycles again after about 1 minute and this repeats.

I built this system so I can eventually (via a different ONT) get up to 10Gbps.

I sent the log from the EX820v since that one tells me there is no DHCP assignment but the only contact I’ve had from Yayzi is a message telling me that ‘they’re working on it’ and a reply back to my original portal ticket telling me that they’re working with CF IT and will get back to me ASAP (and then closed the ticket).

OK, so I applied a Pfsense configuration backup from late mid October and the system has come back up, so this looks like something had gone wrong in pfsense? Since the connection is now working, I’ll close this thread.
