The history data management helps you set the history data collection, periodical 
data collection and storage of the specified ports. The sampling information 
includes the utilization ratio, error counts and total number of packets.

You can use the following commands to add/delete an entry to/from the history 
control table.

Perform the following configuration in Ethernet port view.

History control entry calculates various data at the sampling time interval. You can 
use the display rmon history command to view the information of the history 
control entry.

The RMON statistics management concerns the port usage monitoring and error 
statistics when using the ports. The statistics include collision, CRC and queuing, 
undersize packets or oversize packets, timeout transmission, fragments, 
broadcast, multicast and unicast messages and the usage ratio of bandwidth.

You can use the following commands to add/delete an entry to/from the statistics 
table.

Perform the following configuration in Ethernet port view.

Statistics entry calculates the accumulated information starting from the time 
defined by an event. You can use the display rmon history command to view 
the information of the statistics entry.

After the above configuration, execute the display command in any view to 
display the running of the RMON configuration, and to verify the effect of the 
configuration.

The result is less than the configured lower 
limit threshold-value2
