The program currently looks for any non-leaf switches and removes references to them from leaf switches -- very simple. The LinkSpeed values are the (semi-arbitrary) product of the API's link width and base link speed enumerations as reported for a switch (maximum value across all ports on the switch).</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class="">::::::::::::::::::::::::::::::::::::::::::::::::::::::<br class="">Jeffrey T.
