Port on Device Window

Port on Device window displays the details of all the ports on a device.Table 300 describes the fields that are displayed in the Port on Device window.

Procedure

Port Traffic Stats Window

The Port Traffic Stats window displays information about the port traffic on the node you selected in the View pane. It contains the following elements:

• Port Traffic Trend graph—This line graph shows trends in the data and error rates on the port selected in the ports table below it. The horizontal axis shows the times when samples were taken. The vertical axis shows the data rate on the left side (in packets per second) and the error rate on the right side (in errors per second).

  To display traffic for a different port, select the port from the table below the graph. To change the time period over which to display the traffic trends, select a time period from the list in the upper right corner.

  Note: After a device is discovered, trend data does not appear immediately—it appears only after three polling periods have elapsed.

  To highlight a line on the graph, mouse over the line legend. To remove or restore a line, click the line legend. To see numeric values, mouse over where a data line intersects with a dotted vertical grid line.

• Ports table (on the lower left side of the window)—This table provides information about the ports as described in Table 301. Selecting a port from this table updates the Port Traffic Trend graph to display traffic information about the selected port.
• Counter selection table (on the lower right side of the window)—This table enables you to select which counters to display on the Port Traffic Trend graph. It includes separate tabs for packet counters and error counters. Select the check box in the Show column of each counter that you want to display on the graph. The Per/Sec column shows the rate per second of that row’s counter.
