My customer has N9K-C9348GC-FXP.
Current OS is 7.0(3)I7(9), and willing to upgrade to 9.3(11).
There are some ports that configured 100 speed, duplex full.
When I verify this OS upgrade path by show install all command and show incompatibility,
and there are no problems.
After OS upgraded, and there are no configuarion change.
But the duplex of the ports configured 'speed 100' changes to half duplex.
we change port configure to auto, re-configured the port to full duplex.
But these method didn't work, so I downgraded to former OS (NXOS 7.0(3)I7(9)),
and the duplex went to full duplex.
I know that this OS (9.3(11)) is already end of maintenance SW.
But our customers wants this OS (Because other many N9K is already upgraded to this version).
Is there are any other ways to solve this problem??
Thank you.
