NOTE |
Negative values displayed in either the Ovf used or Total columns indicate a condition where a port released more overflow frames than it consumed. For example, if a user creates a file on port 1 and then subsequently deletes the file using port 2, the port 2 Ovf used value would display a negative number indicating the difference between the number of overflow frames that have been released and consumed by that line. |
The example below illustrates setting the ovf-monitor command to use a scrolling display that refreshes every 2 seconds. In this case, only the activity on port 20 is being monitored.
