MDS 9222i Ethernet port duplex setting not showing.

We have 3 new MDS 9222i's shipped with NX-OS 5.2(2) and we upgraded to 5.2(6b).  Under both release we had some issues with the Ethernet interfaces not coming up.  I think it may be due to issues with auto speed and duplex negotations. So configured all the connected Ethernet ports as:

no switchport auto-negotiate

switchport duplex full

However when I do a show run the "switchport duplex full" does not show.  I have tried various other combinations such as:

no switchport duplex auto

no switchport duplex half

switchport duplex full

No matter what the duplex setting does not show.  I know that auto for speed and duplex is best, but it seems randomly the ports get stuck in Initilization and the only way to get out of it is to ping that interfaces address from the upstream device.

Keep in mind that the output from "show run" or "show run int mgmt0" will only display non-default settings.

You may also find useful information to help debug Ethernet connection by using "show hardware internal mgmt0 stats" or by examining the status of the LAN switch port your mgmt0 is connecting to.

Hope that helps.

Chris,

Thanks for the input. I do know that show run only shows non-default.  I guess I was not clear, this is for the gigabit ethernet ports.  Here is what I mean, if you notice after each command to set the duplex, when I do a show run, it show nothing about the duplex:

MDS9222#01# config t

Enter configuration commands, one per line.  End with CNTL/Z.

MDS9222#01(config)# int gi1/3

MDS9222#01(config-if)# do show run int gi1/3
