Hello,
Recently i am facing and disconnection between my WLC (C9800) and C9300 switch ,after troubleshooting the connectivity between both it has been found that there is an input errors on the C9300 port connecting to the WLC the problem is resolved by shutting and opening the switch port ,but it keep happening regularly, so is there any thoughts ? i am suspecting the port speed between the 2 devices could lead to such problem.
