Using PMP 34
Half duplex port
Scan through the report shown in the following figure.
The first potential issue is indicated by the message “At least one port is running in Half Duplex mode.” PMP indicates
that a network port is running half duplex, which can cause a bottleneck. In this case, half duplex was set in error,
and it is causing an artificial bottleneck for network traffic over that port.
