• Cisco 11.0 BT, 8 Configuring TN3270 Server on the Channel Interface Processor VTAM Host Configuration Considerations for Dynamic LU Allocation SNA Session Switch—End Node DLUR An end node DLUR function is implemented as part of the TN3270 server. The purpose of the DLUR is to allow the routing of TN3270 LUs to multiple VTAM hosts to be performed in the CIP card rather than on the VTAM hosts. The need for this feature will increase with the introduction of the new multi-CPU CMOS mainframe which comprises up to 16 CPUs that appear as separate VTAMs. The implementation of TN3270 server LUs under DLUR also allows the server to learn about t

The VTAM configuration will need to have “DYNAMIC” defined as a template in the LU group. In fact “IBM-ZZ..Z,” where “ZZ..Z” does not match the preceding syntax, will be forwarded as “ZZ..Z.” Note The “E” in the model string refers to 3270 extended datastream. It has no connection with the “E” in “TN3270E”. • Any other string is forwa
