Configuring the RMON History Control Table

Use the RMON Add/Modify History Control Table Row window to configure the RMON history feature so that you can collect historical data for an interface.

To configure the RMON history feature, you supply information that identifies the table row you are creating in the history data table, the interface you want to monitor, the owner of that information, the number of rows of history data you want to collect, and the interval at which data collection should occur.

For general information about the RMON history feature, see About RMON History and Statistics.

Adding a Row to the History Control Table

Procedure:

Step Action
1 From the RMON - History Configuration window, click Add.

5 Enter the number of buckets (data collection instances) you want saved in the history data table.
6 Enter the interval (in seconds) at which you want data collection to occur. This value can be between 1 and 3600 (one hour). The default is 1800 (one half hour).
7 Click Apply.
