Double Ping Responses
I have a problem with my TL-SG1024DE switch where any device connected to port 11 and pinged from a device on another port results in a return plus a duplicate ping, “(DUP!)”. This was tested with several devices the have a normal one response per ping when connected to either port 9 or 13. I also noted after looking at some of the traffic on port 11 that ARP replies are also duplicated.
Is this something that is the result of a configuration error, or a fault of the port? I have tried the usual things like rebooting and powering off and on, but they did not help. There also does not appear to be any firmware upgrade to try for this switch, but I may have missed it. Thanks.
