Usage Scenario
To collect statistics on the specified interface at an interval and save the statistics for future retrieval, run the rmon history command to configure a history control table and add an entry to the table. The system can periodically collect statistics on each type of traffic, including bandwidth usage, number of error packets, and total number of packets.
Precautions
The number of stored records is determined by the buckets number parameter. When the number of records in the table reaches the maximum, the system overwrites the old records with new ones. Statistics include the number of packets, broadcast packets, and multicast packets received by the interface within a sampling interval. You can run the display rmon history command to view history sampling results.
