Configuring History Groups
The RMON History group contains a control and data collection function. The control function
manages the periodic statistical sampling of data from networks and specifies control
parameters, such as the frequency of data sampling, in the historyControlTable. The history
function records periodic statistical samples from Ethernet networks, for example, interval start
time and number of packets. This function places the statistical samples in the
etherHistoryTable.
You can configure the operation of the RMON history that periodically samples any Ethernet
port for statistical data. All ports are preconfigured with histories for 30-second and 30-minute
intervals, and 50 buckets with one sample per bucket. However, you can create additional
histories for a specific port. This allows you to configure the time interval to take the sample
and the number of samples you want to save.
To configure an RMON history group, use the following commands in Global configuration
mode:
