Hi All,
I met a duplex mismatch issue in our new DC.
The port configuration on the N7k and controller is the same as in other DC
Only difference is version of the NxOS on the N7k.
On N7k 5.2(1) works
On N7k 5.2(7) i get below logs :
2013 Aug 21 22:23:24 xxx %CDP-4-DUPLEX_MISMATCH: Duplex mismatch discovered on Ethernet10/8, with LAGInterface0/3/1

How can i fix this issue ? Ports are set up and show the same - 1000 / Full
the messages are annoying as loggs are almost full of them.
Thank you in advance
