Bridge Statistics

The following color-coded Þelds appear in the Bridge Summary Statistics 
window. The Þrst four statistics Þelds are also represented visually by a         
color-coded pie chart (green = forwarded packets, blue = Þltered packets, 
red = error packets, magenta = other packets).

The number of good packets forwarded across the bridge by both ports on the 
network.

The number of good packets Þltered by both ports on the bridge.

The number of packets with an error that were detected by both ports on the 
bridge.

When the bridge is in normal FORWARDING or FILTERING operation, this Þeld 
counts the number of Bridge Protocol Data Units (BPDUs).

If the bridge is in the LISTENING or LEARNING state, no packets are forwarded 
or Þltered Ñ and all packets detected by the bridge are counted in this category.

This Þeld does not include packets already tallied in the Forwarded, Filtered, and 
Received Þelds.

The total number of packets received by the bridgeÕs two ports (this total does not 
include the packets tallied in the Other Þeld).

The Statistics window lets you see statistics gathered at the Ethernet and Remote 
ports of the bridge. These statistics display information about the normal trafÞc 
Þltered or forwarded by the bridge ports, as well as errors encountered by the 
ports and packets that were discarded for various reasons.

As with the Bridge Summary Statistics window, a color-coded pie chart provides 
a graphical breakdown of trafÞc Þltered or forwarded by the bridge ports, as well 
as errors and non-bridged trafÞc (green = forwarded packets, blue = Þltered 
packets, red = error packets, magenta = other packets).

All statistics are read directly from the device, and are updated with each poll 
from SPECTRUM Element Manager to the device.
