Failed to upgrade X690 and X440-G2 from 31.7.1.4-patch1-77 -> 32.6.1.5-patch1-2

Hello,

we had some problems with the upgrade to 32.6.1.5-patch1-2 over the weekend. I wanted to ask if this is the case for you too.

When we updated the X690 the 40G ports no longer came up. They were active but we see no connection to the other switch. All 1G ports are working, only the 40G doesen't work. We use the new Image x690-32.6.1.5-patch1-2.xos  (not ONIE). After we roll back .. everything is working. 

When we updated the X440-G2 for some reason, the ssh service was no longer active after the upgrade restart. As soon as it was reactivated via the console port it worked.

Does anyone know the problem?

Best regards,

Markus

I found an article that could be our solution to the X690 problem.

Cause

This is a known issue, caused by a Forward Error Correction (FEC) mode being applied during the insertion of 100G optic that then conflicts with the 40G optic.

In that case the ports would stay down. 

The Error is no longer present in the version you are upgrading to.

If you would have plugged an 100G optic in the past, the 40G optic wouldn't work even before the upgrade.

That's true, but the switch is connected to an MLAG with two X690s and those are the problem (because of the version 31.7.).

We will now update the one again and do the commands on the MLAG switches .

configure port 57 forward-error-correction on cl74

Hopefully it will work out in the end.

There's a bug where the SSH key can get corrupted and have to be regenerated after an upgrade https://extreme-networks.my.site.com/ExtrArticleDetail?an=000076452
