GS108E Duplicate Packets found when pinging

Hi MrJonny,

Welcome to the community! :)

Based from the firmware version you have mentioned, you have GS108Ev3 switches (v for version).  Kindly answer the questions below:

a. Kindly try to disconnect the GS108Ev3 that still has the duplicate packets issue from the existing network.  Then, connect a PC directly to it.  Make sure to set a static IP Address on the PC that is within the IP range of the IP address set on the GS108Ev3.  Open command prompt on the PC then try to continuously ping the GS108Ev3 IP Address.  Are you still getting duplicate packets when pinging? 

b. Kindly try using another ethernet cable connecting the same GS108Ev3 and PC.  Again, open command prompt on the PC then try to continuously ping the GS108Ev3 IP Address.  Are you still getting duplicate packets when pinging? 

c. Kindly try using another PC then connect it directly to other port/s of the same GS108Ev3.  Make sure to set a static IP Address on this other PC that is within the IP range of the IP address set on the GS108Ev3.  Open command prompt on this other PC then try to continuously ping the GS108Ev3 IP Address.  Are you still getting duplicate packets when pinging using another PC? 

d. What is the behavior of the port LED light where the PC is connected on the GS108Ev3 that has the duplicate packet issue?

I look forward to your response.
