While working on UTMC OTUs I found it quite difficult to view the Control and Reply data simply at site. So I lashed up a bit of Visual Basic Code to help me out. Connect your laptop network wise on the same netmask as the OTU, you should find this software pretty simple to use as it does not really do that much. You can double click the status bar at the bottom to input IP Address, Scan, Poll etc.
Let me know how you get on, I am sharing this as I guess it may help others too.
Scoot Replies can get cleared when doing an SnmpGet to read the data. So Polling of Scoot Dets is Off by default in the Options.
