To limit the number of sessions a single independent LU can establish per link station, you can use the MAXSESS operand on the following definition statements:

• The LU definition statement in an NCP major node, switched major node, or dynamic reconfiguration file
• The PU definition statement in a model major node
• The CDRSC definition statement in a cross-domain resource major node

This action prevents a single independent LU from using all of the session control blocks generated in the NCP.
