Since you actually used Juniper AOCs - what was their stance on this?

I can see the usual "this is not a genuine $Vendor optics, so if it does
not work, it's not our problem" stance, but if all involved devices plus
optics are "same vendor", it's very much their problem to make it work...

Re: [j-nsp] 100G DAC issue between MX204 and QFX5110

2019-06-20 Thread Antti Ristimäki
+1

We've had some serious issues with Juniper AOC cables between QFX and MX. It 
worked with the factory-installed version 15.1X, but then after upgrading QFX 
to >=17 train caused the AOC work only between two QFX switches, but not 
between QFX and MX, regardless of FEC etc. configuration. Then finally in some 
SR release AOC again started to work.

This was AOC specific issue and in fact we have more or less abandoned AOC 
cables, but nevertheless 100G seems to be much more difficult to interop than 
previous speed generations.

I tried 17.3 and 17.2 based on a PR, but let me try 17.4.  Can't hurt.  So
far none of the 4 versions have done anything for me.

Is it just me or does 100GE have lot more interop issues than we had
with 1GE and 10GE?

Vendor rep explained it as MSA being too ambiguous so both can do
everything right and still not interop, unsure if defensive or
factual.

We've actually had the reverse issue where 17.4 is the only release that
some DACs will function. Any 18.x release seems to break them. These aren't
Juniper coded DACs, but just generic coded:

We have tested flexoptix 3rd party DAC between MX204 and QFX5120/QFX10002
with mixed results. Per release notes/ HCL, DAC isn't supported on MX204
until 18.2

https://apps.juniper.net/hct/product/#prd=MX204

We couldn't link anything with mx204 dac on anything below 18.2. There are
also a few DAC related PRs in the 18.2r1 release notes.

[j-nsp] 100G DAC issue between MX204 and QFX5110

2019-06-19 Thread Eric Krichbaum
Has anyone gotten the Fiberstore 100G DAC to link up between a QFX and an MX?  
I got link between 2 MX using it without any issue but haven't had any luck to 
the QFX.

They detect ok:

Xcvr 48  REV 01   740-061001   C1905258091   QSFP28-100G-CU1M
Xcvr 49  REV 01   740-061001   C1905258082   QSFP28-100G-CU1M

Just won't come up:

et-0/0/48   updown 
et-0/0/49   updown

Updated the 5110s to the JTAC recommended 18.1R3 but haven't established link 
to the MX's yet to bump them up from the default 17.1.

Thanks,
Eric
