Description
Use rmon history to create an entry in the RMON history control table.
Use undo rmon history 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
interface, and saves the statistics as an instance under the leaf node of the etherHistoryEntry table. The
maximum number of statistics records can be saved for the entry is specified by buckets number. If the
maximum number of the statistics records for the entry has been reached, the system deletes the earliest
record for the latest one. The statistics include total number of received packets on the interface, total
number of broadcast packets, total number of multicast packets in a sampling period, and so on.
You can successfully create a history control entry, even if the specified bucket size exceeds the history
table size supported by the device. However, the effective bucket size will be the actual value supported
by the device. To view the configuration result, use the display rmon history command.
You can configure multiple history control entries for one interface, but must make sure their entry
numbers and sampling intervals are different.
The device supports up to 100 history control entries.
