The ONT's in Christchurch are (mostly) done by Enable, on the Coast it would be Chorus, so they are probably different.

Whereabouts on the Coast? Must be something pretty important to make you move there, from Canterbury (I grew up on the Coast, and most of the people I went to high school with headed over the hill as soon as humanly possible).

I genuinely dont see the need to 'monitor' the ONT.

Fault finding on a UFB connection is 'what colour is the optical light?' Green = good, red = bad. Admittedly, you see more from the chorus side, but really not that much more.

If you have a bunch of distributed connections, get routers that allow you to monitor with SNMP. VPN them all together, and then run LibreNMS at your head office.

Even better, go with an ISP that can give you a hosted WAN. You might even find an ISP that has an API for you to plug in to, that allows you to view the chorus ONT info.

Are you sure that you're not hitting so something on the other side of the ONT which the ISP runs??
It's layer 2 and when configuration is complete there should be no locally accessible IPs.

You've been given consistent advice to not mess with it and advise on how to monitor the link. And chosen to ignore it.

If you screw it up or annoy your ISP and they terminate your account for attempting to hack it their services don't say we didn't warm you.

You can't really fix stupid.

Like others I'm lost when it comes to understanding what the point on monitoring the ONT is - any sort of layer 3 monitoring isn't going to deliver anything meaningful at all, and more importantly isn't even going to tell you whether the Internet is actually up or not.

One way to monitor the ONT is to monitor the status of the copper port facing the ONT on your RGW or similar. If you see a port down event or status change then the ONT could have downed the port from its side which means it may have reset or something. This will provide a hint but may not be definitive.

Similarly you can monitor the ether port speeds from your end to see if anything has changed.

Otherwise as others are saying, the fibre network is transparent to layer 3 so there is nothing to reflect anything back to you.

If you want to play, try sending CFM packets (802.1ag) and see if anything responds. These are the layer 2 version of the common ping however, the network needs to be set up to reflect those back and it is not usually enabled. Unfortunately I don’t know of any program that would do this - I have always used test gear with that protocol.

Fat Controller deeply thanks everyone for their input. Even the people calling me stupid have a special place in my heart.

I aim to please.
My main argument is.... Why?
You have a best efforts service so it'd not like you can fine the ISP because of lack of service.
If the internet is down you can't tell anyone unless you have a mobile data card to send something out of band.
Are you planning to robo call the ISP saying your line is down to log a call?

So I do question on something completely outside your control outside rebooting the router what is the value in the effort.

This is 100% my favourite thing about Geekzone. Someone asks how to do something and everyone can't WAIT to pile on as to why you shouldn't do it, why they think it's a bad/pointless idea.

Even after 1 person has said it everyone else has to say it too.

Personally, I don't think you should try and monitor the ONT.

Personally, I can see a reason to monitor the ONT. 🤩

Out of band monitoring
1. Relying on the medium that you are monitoring to report a fault is flawed
Sometimes, you do need visual confirmation &
Is a person present to confirm the red light & do a reboot?

🤪 It's been a while since I read the beginning of this thread, but I seem to remember that point 3 does not apply in this case. 😜

Please keep this GZ community vibrant by contributing in a constructive & respectful manner.

@Fatcontroller Any reason why you cant monitor the PPPOE connected/ disconnected status in the router instead? As if PPPOE is disconnected, the Internet is definitely offline. And there is only a narrow range of scenarios where PPPOE is connected but internet still offline.
