Disable Bridge to disable bridging across all interfaces.
Bridge Statistics
There are three statistics windows available for the 9H42x-xx module: the
Statistics window (accessible from both the Module View and Bridge Status view
port menus) displays any available RMON-based statistics; the I/F Statistics
window (also accessible from the Module View and Bridge Status view port
menus) displays MIB-II interface statistics; and the Performance Graphs display
statistics related to the bridging function being performed either by an individual
interface, or by the device as a whole. The Statistics and I/F Statistics windows
are described in Chapter 4; information about Performance Graphs follows.

Performance Graphs

Bridge Performance Graphs provide a color-coded strip chart that shows you the
traffic being bridged through all networks or an individual network connected to
the selected 9H42x-xx module. 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; the y axis measures the number of packets or errors that are
processed by the module as a whole or by one of its bridging interfaces.
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 Status
menu.
or
From the Module View window, click on the Bridge label just above the port
status display; the Bridge menu will appear.
2. Click to select Performance Graph..., and release. The Bridge Performance
Graph window, Figure 5-2, will appear. (The individual port Bridge
Performance Graph windows are similar, except that they display a graph
applicable to the selected interface.)
