Description
Use the rmon history command to create an entry in the RMON history control table.
Use the undo rmon history command to remove a specified entry from the RMON history control
table.
After an entry is created, the system periodically samples the number of packets received/sent on the
current interface, and saves the statistics as an instance under the leaf node of the etherHistoryEntry
table. The maximum number of history entries can be saved in the table is specified by buckets number.
If the number of the entries in the table has reached the maximum number, the system will delete the
earliest entry to save the latest one. The statistics include total number of received packets on the
current interface, total number of broadcast packets, total number of multicast packets in a sampling
period, and so on.
When you create an entry in the history table, if the specified history table size exceeds that supported
by the device, the entry will be created. However, the validated value of the history table size
corresponding to the entry is that supported by the device. You can use the display rmon history
command to view the configuration result.
