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.
