In order for Campus to build a LANE topology, you need to be running ILMI on all of your nodes. Campus must also have properly Data Collected the LES/BUS and LECS for the domain. For debugging, you would want to enable core and corex under Campus Manager > Admin > Campus Data Collection > Debugging Options to isolate Data Collection problems, and atm, lane and laneconfiguration for ATM-specific issues. After a new Data Collection, the ani.log will have the details.
