5-6 Bridge Statistics
To enable or disable bridging at all ports from the Bridge Status window:

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.
