Port Statistics
The Port Statistics dialog box displays the statistics for data sent and received
by the switch ports since the switch was last powered on, was restarted, or
since the statistics were last cleared.
To display this dialog box, choose Monitor>Port Statistics from the Device
Manager Web interface. See the Device Manager Web interface online help for
additional information and procedures.
The types of port statistics collected and displayed are grouped under these
tabs on the Port Statistics dialog box on the Device Manager Web interface:
• Overview tab: Use this tab to display the specific numbers of error
packets received on and sent from the port, which is a level of detail that
is not available from the Dashboard graphs.
The number of error packets can mean a duplex mismatch,
incompatibilities with the port and its attached device, or faulty cables or
attached devices. Any of these problems can cause slow network
performance, data loss, or lack of connectivity.
