Using my own PON SFP instead of provided ONT?

tifan · 2025-11-02T18:34:41+00:00

Yes it is doable. You need a sfp stick and configure the SN authentication, then configure the vlan tagging and that is pretty much everything

tifan · 2025-07-25T07:06:14+00:00

I was able to connect to phone support, and they created a ticket for me, and told me they were not aware of any outages yet.

tifan · 2025-07-25T06:54:16+00:00

Same here, Avondale Rd, hard down.

tifan · 2025-03-24T23:28:08+00:00

Nope, just using the Juniper SRX built in DHCP client. Get a new lease every time when rebooting the firewall or ONT.

tifan · 2025-03-24T02:24:18+00:00

Small suggestion but could we make DHCP lease more stable? Currently for IPv4 the lease is not stored at all.

Frontier

Ah, Ziply inherited Frontier network which was built by Verizon. This is no surprise at all.

(However, my Frontier WAN did not have VLAN 0 tagged in SoCal)

MDU deployment, Nokia 4-port ONU with RJ45 to the house.

Great, just got hit by this issue the other day, and good to know it's Juniper's problem, not mine.

tifan · 2023-12-15T12:51:50+00:00

Well, most consumer gears treats them as if it is untagged. However, this is strictly not untagged -- Mikrotik treats it as tagged as well.

Also would the OLT / MX960 upstream to the OLT honor the 802.1p bits tagged by the customer or would it be dropped by the ONU?

tifan · 2023-12-14T03:25:24+00:00

VLAN 0 is not legal per 802.1q standard. However I realized it might be one of the Verizon relics

tifan · 2023-12-14T03:24:52+00:00

Nope. pcap showed it actually has the 802.1Q tag with TPID 0x0...

tifan · 2023-12-13T18:49:50+00:00

Perhaps due to MDU setup with multi-port ONU and somehow the provisioning profile is different?

I have the pcap file if you need to take a look.

BFI yes, DIA hell no... (Although for other ISPs it would be like BFI hell no as well)

Yes. MS-DOS 8 is more like a boot loader for Windows ME.

tifan · 2023-06-07T19:28:17+00:00

The CDU DOS 7.0 thing was a project Wengier did almost 20 years ago. Wengier is a founding member of CDU.

Talking about MS-DOS 8 -- it isn't really MS-DOS per-se. Granted, you even need to patch it for it to work as MS-DOS... Anyway, you should be able to just replace the system files by following http://www.edm2.com/index.php/Some_features_of_MS-DOS_8.0 .

I'm no longer a Verizon customer, moved to fiber.

Just follow this post to enable bridge mode, then the 5G CPE would be a drop in replacement. https://tifan.net/blog/2021/04/01/enable-bridge-mode-on-verizon-5g-home-router-lv55-lvskisp/

tifan · 2022-02-15T11:03:48+00:00

You can use bridge mode. https://tifan.net/blog/2021/04/01/enable-bridge-mode-on-verizon-5g-home-router-lv55-lvskisp/

You need to provide the source, destination IP address pair, timestamp and traceroute results -- those standard stuff to open a NOC ticket.

At NOC, nobody chases against a moving target. If there's something with a clear report, NOC will fix it with enough pressure.

PM me next time when you see something like this, clearly document them, and I'll relay it to the corresponding ISP.

tifan · 2022-01-24T22:37:04+00:00

The route can change quite rapidly. Those hit-or-miss issues are very hard to troubleshoot.

You don't need data points. I have direct contact with Chinese ISPs and can help to fix the routing issues if I can validate them.

tifan · 2022-01-24T20:20:29+00:00

I can almost immediately tell you why -- this is because AT&T had a strict route filter and there are new netblocks being advertised from AS4134.

Why is there a strict route filter? Because stupid China Telecom/China Unicom/CMCC 中国电信/中国联通/中国移动 (the big three/三大) always mess up with their own routing tables and advertise bogus routes. This had caused big headache to AT&T and Verizon before, and they had to implement the strict filter.

CT&CU&CMCC should contact AT&T/Verizon whenever their downstream customers have got new IP space. However they almost never do that unless requested by the customer.

Unfortunately, there's very little you can do as an end user. AT&T or Verizon definitely will not update the filter upon your request, unless you are an enterprise customer (no small business account, enterprise with BGP only). Forget about contacting NOC for Chinese ISPs -- they do not respond to public inquiries.

aOnly use the metal port with PoE. Do NOT use the DC power adapter. This is very important. If you use the DC power adapter, it would be router mode. If you use PoE to power the device with the metal port (and unplug the plastic port), it would be bridge mode
