Parameters

Parameter	Description	Value
entry-number	Specifies the index number of a history control table MIB entry mapped to a historical sampling object.	The value is an integer ranging from 1 to 65535.
buckets number	Specifies the capacity of the history table mapped to the historical control table entry, specifically, the maximum number of records in the history table.	The value is an integer ranging from 1 to 10.
interval sampling-interval	Specifies the sampling interval.	The value is an integer ranging from 5 to 3600, in seconds.

Usage Guidelines

Usage Scenario

If you want the system regularly collects data about a specified interface and stores these data for future use, the rmon history command can be used to configure the RMON historical sampling function.

Precautions

The number of collected data that can be stored is determined by buckets number. When the capacity of the history table reaches the maximum, the system will delete the earliest records and store new statistics at the same time. Statistics includes the total number of packets, broadcast packets, and multicast packets received by an interface in a sampling period. You can view the historical sampling result using the display rmon history command.

Example

# Create a history control table entry with the index number as 1, table capacity as 10, sampling interval as 5 seconds, and owner as user1 to enable the historical sampling function on an interface.
