Top Conversations
10-16
The right column of the table shows the percent that this conversation
contributed to the total traffic on this segment.
Possible reasons that a conversation may not be listed in the table when a
conversation has occurred on the segment are:
I The conversation was not in the top number of conversations (for
example, the Top 10 conversations) selected for display for each segment
One end of the conversation is a device (hub, switch or router). Only
I
conversations between end nodes are shown.
I One or more of the end nodes was not found by the discovery/topology
process.
I The segment does not contain either of the end nodes of the conversation
but the conversation traverses the segment. For example, a conversation
traverses Segment 1, Segment 2, and Segment 3, but the conversation is
only reported on Segment 1 and Segment 3, where the end nodes reside.
(Conversations in which the end nodes are in different segments will be
listed in both segments.)
Conversations involving nodes that utilize less than .1% of the segment
I
bandwidth are not reported.
I The segment was not discovered by HP TopTools.

You can use the Top Conversations table to determine who is using the
bandwidth when utilization is high for a segment.
