What do you have connected to this port? It's possible that the device connected to it is triggering auto negotiation failures. I would suggest to hard code speed and duplex on the nexus port and the remote port. See if you still get the same error.

Hi Cofee
The device that is connected to the interface is a PC 10gigabit nic...
I will try to hard coding the interface and see if that will solve it.

Hi So I hard coded the interface
I'm still seeing the package drops... the interface still flapping. but the renegotiation speed is not happening anymore.
ā07-20-2017 09:14 AM
Did you hard code PC nic as well? if you haven't you would need to do that as well.
ā07-31-2017 11:54 AM
Still drop after hard-coding the PC- NIC.. they are both on 10GB and full for duplex... but still the result.... the port is down twice a day
ā07-20-2022 08:20 AM
Did you resolve the problem.pls help me also as facing same problem.
ā07-19-2017 04:37 PM
It appears that you have issue with interface speed negotioantion. Can you hard set the speed to be compatible to whatever device this interface is connected to (e.g speed 1000)?

UPDATE:
So I did hard-coded both the switch port and PC nic to the same speed and duplex to full, and still not working....
I even change the switchport to another port and still a no go...
Any other ideas???
Thank you

Is it possible to change NIC or use another host that has a 10 gig port?that would rule out any issue with the remote NIC/host, since you have already tested the nexus side by using another port.
did you try replacing the patch cable ?

Hi Cisjay,
Did you solve the problem? I have faced the similar problem, Nexus vPC link keep droping the traffics.

issue not solve by hard coded speed and duplex alone, you need to disable auto nego too to make PC-NSK connect.
