Dear All,
I am seeing lot of Input Errors, this is between LAN uplink of Router port GE 0/1 to Cisco Switch 2960 Gig 1/0/6, is this input errors and overrun is normal between the LAN uplink? Below configuration for reference, I am seeing lot disconnection between our office to our DataCenter, is this because of this input errors, overrun and unknown protocol drops
