4.13.3 Port Statistics
In this page, you can view operation statistics for each port. The statistics that can be
viewed include Link Type, Link State, Rx Good, Rx Bad, Rx Abort, Tx Good, Tx Bad and
Collision. Rx means the received packet while Tx means the transmitted packets.

network cable is not connected well, the network performance of the port is poor…etc.
Please check your network cable, Network Interface Card of the connected device, the

Click on Clear Selected to reinitialize the counts of the selected ports, and Clear All to
reinitialize the counts of all ports. Click on Reload to refresh the counts.
