Bridge Statistics

The following sections describe the Statistics windows available for the selected bridge, both at the device and port levels.

Performance Graphs

You use the Bridge Performance Graphs to view a color-coded strip chart that shows you the trafﬁc being bridged through all networks or an individual network supported by your device. You can conﬁgure the display to show frames ﬁltered, forwarded, and/or transmitted, as well as the number of errors. The graph has an x axis that indicates the 60 second interval over which charting occurs continuously, while its y axis measures the number of packets or errors that are processed by the selected module as a whole or by one of its bridging interfaces.

For the 9A128-01, selecting the Detail button on the device-level performance graph window allows you to compare the packets forwarded, ﬁltered, or transmitted across all networks supported by the 9A128-01, as well as errors on all networks; for a selected bridged network, the Detail button allows you to view the number of packets forward to, or received from, each other network supported by the 9A128-01.

You can select the statistics you wish to monitor by using the menu buttons provided; when you change Performance Graph parameters, the graph will refresh and generate a strip chart based on the newly deﬁned parameters.

To access the collective Bridge Performance Graph window:

1.From the Bridge Status window, click on to display the bridge menu. or

From the Module View window, click on the Bridge label in the module display; the bridge menu will appear.
