i have one interface time to time discord the packets and after change the port the link become UP and forwarding state.

i found outerror on that interface  (G1/0/23)

Hello EMON,

According to your information, the speed of the port is 100 Mbit/s and the port works in half-duplex mode. This may be the cause of packet loss.

Please check whether the interface works in auto-negotiation mode. If the auto-negotiation mode is used but the parameter negotiation is incorrect, try to manually configure the port rate and duplex mode. The commands are:

interface GigabitEthernet1/0/23

   undo negotiation auto

   Speed 1000

   duplex  full


speed
