forwarded through the bridge to another segment.
Segment Mismatch
The routing information Þeld of a SpeciÞcally Routed frame contains LAN
Segment In (Local Segment)ÑBridge NumberÑLAN Segment Out (Target

LAN Segment Out speciÞed in the frameÕs Routing Information Þeld, the bridge
logs a Segment Mismatch and discards the frame.
Duplicate Segment
A bridge discards a frame if the frameÕs Routing Information Þeld identiÞes a
particular segment more than once.
Hop Count Exceeded
An All Paths Explorer frame is discarded when it exceeds the number of routing
descriptors (bridge hops) speciÞed by the Hop Count Limit.
The Pie Chart button lets you select a predeÞned set of frame type statistics and
display them as a pie chart. When you click on the Pie Chart button, a pop-up
menu appears that lets you choose Received, Transmitted, or Filtered statistics.
When you make your choice, the SR Pie Chart window opens with the
appropriate set of variables already selected.
