ICX 7850-48F 1 Gig not connecting to ICX7450 or ICX7750

This seems like a very simple configuration, wondering what may have changed to make it not work intuitively.

Trying to get our 7850s stood up in the lab, these are the 48Fs, so the 1/10/25G ports on module 1.

I can’t seem to get the 1G links to connect to either a 7450’s 1/10 ports on module 2 or a 7750’s 1/10 ports on module 1. The 7850 shows up but the 7450 and 7750 shows down. Is there something in the configuration I’m missing?

Everything looks normal to me from a configuration standpoint. What code are you using on each side? I am assuming you swapped fiber already? You may want to open a case and see if this is something we can troubleshoot and/or reproduce.

Also, any difference if you set one side to slave?

Hi Ben, 8.0.90 on all devices. Tried doing 1000-full-master and 1000-full-slave and that didn't change anything, not even the configuration entries.

Wondering how something this simple missed QA.

Just got in contact with Joe Rizo, it's an issue with gig-default, the 7850 is default neg-off and other ICX7XXX series default is auto-neg.

Were you able to get the port up then using the gig-default options? It looks like there are some mentions of this in the 8090 management guide:

Hi Ben, Yes,

NOTE
If a non ICX7850-48F 25G fiber port is connected to ICX7850-48F 25G port at 1G speed, then for ICX switches disable the "auto-negotiation" of that port using the gig-default neg-off command. For non ICX switches, an equivalent command or configuration that is vendor specific is used.

Is correct and fixed my issue, it's fairly obscure though, now I know and hopefully more will in the future as well. Thanks!

Hi Duke,

I mean, apply the gig-default neg-off command to ICX-7150 SFP ports?

Thanks
