9E312/9E423 Module Bridging
3-8 Bridge Statistics
Bridge Performance Graph Window Fields
You can select the following statistics to display in the Bridge Performance Graph
or Bridge Port Performance Graph. Statistics are provided numerically (as an
average or peak value) and graphically. The device is polled for the graphed
information every 2 seconds, and numeric values are updated based on this poll.
The graph updates at the fixed two second interval. For the first 60 seconds of
graphing, you will note the graph lines extending as each interval’s data is added
to the graph. Once the first 60 seconds has passed, the newest data is added at the
right edge of the graph, and the oldest data is scrolled off to the left.
Peak statistics are based on the peak level of activity returned from a single poll
since the Performance Graph window was invoked. A date and time is provided
for peak levels.
The Average statistics are updated every 2 seconds as averaged over the previous
four poll intervals (i.e., averaged over a sliding eight second time window).
Frames Forwarded (Green)
Forwarded The number of frames forwarded by the 9E312/9E423
Module’s bridge, at the device or port level.
Nothing The Frames Forwarded function is currently not
measuring any statistics.
Filtered (Magenta)
Filtered The total number of frames filtered by the 9E312/9E423
Module’s bridge, at the device or port level.
Nothing The Filtered scale is not currently measuring the number
of packets filtered by the bridge at the device or port
level.
Errors (Red)
Total Errors The total number of errors that all bridging interfaces on
the device, or an individual bridge interface, has
experienced during bridging.
Nothing The Errors scale is currently not measuring any type of
error packets coming through the device or port.
Xmitted (Blue)
Xmitted The total number of frames transmitted by the selected
bridge interface, or all bridge interfaces.
Nothing The Xmitted scale is not currently measuring the number
of packets filtered by the bridge or the individual
interface.
