To determine the physical Level or frame ID value to set in Router Manager Configurator, from NV9000 SEUtilities, go to View | Virtual Levels and select the appropriate ID. In order word, level or frame id = column id in table Virtual levels in SE-utilities

The size is variable, and it can change each time you read mnemonics from the system.  You would need to query the database to obtain the number of sources or destinations in advance of reading them all using 0x3022.

In order to set the right level size, save your config, open putty to your app server, enable debug for com.miranda.icontrol.routers.nv9000virtual.NV9000Virtual to debug in log4j and restart the iControl Router service. Then open log file router.log and use the grep command for string source size and destination size.
