Displaying Port Statistics
Port Statistics display key statistics from the Ethernet-like MIB for
each port. Error statistics on the traffic passing through each port
are displayed. This information can be used to identify potential
problems with the switch (such as a faulty port or unusually heavy
loading). The values displayed have been accumulated since the
last system reboot.
Select the required port. The statistics displayed are indicated in
the following figure and table.
