Run:system-view,The system view is displayed.
Run:interface { ethernet | gigabitethernet } interface-number,The interface view is displayed.
Run:rmon-statistics enable,RMON statistics function is enabled on an interface.
Run:rmon history entry-number buckets number interval sampling-interval  [ owner owner-name  ],A history control table is created and an entry is added to the table.

 NOTE:
-As recommended by the RMON specifications, each monitored interface should be configured with more than two history control entries. One entry is sampled every 30 seconds while another entry is sampled every 30 minutes.
-The short sampling interval enables a monitor to probe the sudden changes of traffic modes, and the long sampling interval is applicable if the interface status is relatively stable.
-Each history control table stores 10 records. When more records are generated, the old ones are overwritten.
-To reduce the impact of RMON on system performance, the sampling interval of the history control table should be longer than 10 seconds. In addition, an interface cannot be configured with too many entries for the history control table and alarm table.
-If the RMON statistics function is not enabled on an interface, statistics in the RMON statistics table and history table are 0.
