Solved!
Go to SolutionDell N4032F Po1 Learning to forwarding
Hi,
I got 2 switch N4032F stacked and my Po1 have some problem.
each seconde i got in log this :
Po1 is transitioned from the Learning state to the Forwarding state in instance 0
Po1 is transitioned from the Forwarding state to the Blocking state in instance 0
I got many Po1 with the same equipement connect in the same switch, with the same configuration. Why it happen just on this Po ?! Other equipement is a Mikrotik CCR1072.
Thank you

Hi,
It is spanning tree switching, did any of the ports go down when this switched?

Page 770 http://downloads.dell.com/manuals/common/networking_nxxcli_en-us.pdf you could try to increase the hello time of spanning tree to see if it will stop switching.
