I need a capture file that can be opened in Wireshark that shows ATM cells to illustrate some lecture notes. The file the Wireshark site has does not show any detail for ATM, despite the file name. A search has uncovered no other file. GNS3 does not support ATM link captures. If anyone has such a thing they could share with me, please contact me offlist. Kenneth M. Chipps Ph.D.
