Displaying the RMON History Table
The RMON - History Configuration window displays information about the
interfaces that are being monitored for historical data.
Use this window to display the actual history data collected from an
interface or to delete a row in the table. From this window you can access other
windows that allow you to add a new row to the history control table or modify an existing
row.
For general information about the RMON history feature, see About RMON History and Statistics.
Displaying the History Data for an
Interface
Procedure:
Step |
Action |
1 |
In the RMON - History Configuration window,
locate the interface for which you want information. |
2 |
Click the Show History Table button next to
the interface.
The RMON - Ether History Table for the interface is displayed. |
Note: By default, every
interface on the device has two entries defined in the history control table. One
entry specifies a control interval of 30 seconds, and the other specfies a control
interval of 30 minutes. The 30 seconds period allows for the detection of sudden
changes and the 30 minute period allows for steady state behavior of the interface.
Deleting a Row in the History Table
In the RMON - History Configuration window, locate the row you want to delete and click
Del.
The row is deleted immediately.
