9E312/9E423 Module Bridging

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)

ForwardedThe 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.
