Apologies for the delay in reply Work(TM) has been off the charts recently.  
Thanks a million for your hard work so far !

 Unfortunately I don't have any spare optics either (we only had a limited 
number of the HotLava cards and they're now all spoken for in production boxes).

I'll see what I can do, maybe I'll find another way to get hold of something.  
I really want to test it ! ;-)

Re: Viewing SFP diagnostic data in OpenBSD ?

GPON involves encryption keys (because the light is split off so that a
handful of other customers have the same signal as you). In the UK this
is exclusively done by a telco-provided box, they won't give you the
keys to use in your own hardware. but it just spits out an ethernet
connection that is tunneled to the ISP (typically done with pppoe, but
not an absolute requirement), and would connect to a separate router
which is either ISP-provided or your own.

(Dragging it slightly back on topic, OpenBSD works fine with the usual
pppoe setup :)


Yes, that is the case. I have and ZTE gear installed,
optical+router+wireless+voip.
There is a word here someone was able to move all setup to a single
computer with a special optical board, eliminating the ISP equipment,
just by monitoring the optical and extract the useful information.

Of course the pppoe works fine on OpenBSD, I used it a lot when I was
on the copper.

Thanks.

1 Gb/s on fiber is pretty much implemented where i live now (.ro). The
sad thing is the ISP is using GPON with ONT on client side. I wanted
to use some OpenBSD based router but I am not sure it is easy to put
together the necessary hardware and driver/pppoe configuration. There
are all kinds of settings involved even at ISP side and I am not sure
they are happy to set up for you.

What are they using there for authentification?

I heard that a few years ago the people in Zurich voted that everyone
gets FTTH.  So the network is now provided by ewz, the local
electricity company, or by Swisscom and almost every household is
about to get an OTO wall outlet with two possible fiber ports.

You can choose between a number of professional and consumer-grade
ISPs, so they don't even lock you in.  The ISPs either give you a
typical fritzbox CPE and/or a media converter (like the TP-Link
MC220L), but it also works fine with the mentioned SFP.  I now have
1Gbps Internet, fixed IPv4+v6, simply with DHCP (dhcp6c is needed to
get the assigned IPv6 prefix for reassigning it to rad(8) internally).
At least one (consumer-grade) ISP even offers 10G, at least
theoretically, but I didn't dare to try them out.

There is really nothing in the spec for bidi optiocs. If you can plug it
into a supported nic (ix/ixl for now) you should see the Tx wavelength
but there's nowhere to retrieve the Rx wavelength.

Nice to have an FTTH setup that just lets you use your own kit! The few
UK providers doing ethernet FTTH are mostly using Genexis boxes I think
(probably for laser safety reasons, their fibre management makes it hard
to look straight into a disconnected fibre).

I have an em(4) with SFP in my FTTH gateway, a Lanner LEB-6032.  I'd
be happy to test any em(4) diff for it.

I had to get a special SFP that is compatible with the FTTH specs here
in Zurich.  It is using an asymmetric wavelength, Tx1310nm and
Rx1460-1580nm, and I am wondering if your code could show this fact
somehow.

https://www.flexoptix.net/en/wideband-sfp-bidi-transceiver-1-gigabit-sm-tx1310nm-rx1550nm-10km-12db-ddm-dom.html?co8658=83928

em6: flags=208843 mtu 1500
lladdr 00:90:0b:55:3d:e4
index 7 priority 0 llprio 3
groups: egress
media: Ethernet autoselect (1000baseSX full-duplex)
status: active

But I also have many different "regular" SFPs here that I can plug
into the second em(4) fiber port test the diff.

The attached dmesg is a few days old.

If you are also interested in the mentioned em(4) capable hardware, just
contact me off-list and I'm going to see, what we can do concerning the

yepp, e.g. in the following appliances :

http://www.lannerinc.com/network-appliances/x86-rackmount-network-appliances/?option=com_content=article=1683:nca-4210=25:rackmount


There are 2 SFP slots onboard and we are also using the optional module
on the right side of the appliance but not as RJ-45, but with 8x 1 GigE SFP.


Whereas the 10 GigE Modules we are using in some setups, are already ix.

Re: Viewing SFP diagnostic data in OpenBSD ?

[Tom Smyth]

Hi Rachel
Im not certain..  i havent tried this on openbsd  but i would do an snmp
walk and see if there are stats displayed on  your sfp interfaces  can you
check the mib from the chipset manufacturer ?

Also if you  check  man driver name  e.g.
man ix  for intel 10g nics there may be additional info specific to the
cards there

I hope this helps

I don't think that code has been written yet.
