port. The information about the latest sample, including bandwidth utilization, the number of errors, the
total number of packets, and so on, is also displayed.
After a history entry is created on a port, the system collects statistics of the port at a certain interval,
and saves the information in the etherHistoryEntry table. You can use the command to display the
records saved in the table.
