Note that the name LCL701 in the sample  V NET  command is the VTAM name of the terminal.  This name is  not  related to the LUname specified in the zPDT devmap. A 3270 session has  both an aws3274 LUname (specified in the zPDT devmap) and a VTAM name (specified in  VTAMLST). Also, MVS operator consoles are not specified in VTAM and have no VTAM  name. This terminology is unfortunate because the aws3274 LUname (used to link a  TN3270e session to an aws3274 definition) is not necessarily the same LUname associated  with a VTAM operation.  Also, note that zPDT does not support the VMAC function from z/OS. The only virtual mac  supported is generated on z/VM with the layer-2 vswitch. Important:  Starting with z/OS 2.3, the OSA/SF program (used to help configure non-QDIO  OSAs) is not available and the replacement function is not supported by zPDT.  When using the non-QDIO interface to the emulated OSA-Express2 function, the key  parameters might look like the following example: This example assumes that z/OS contains an appropriate CTC or OSA definition for  addresses E20 and E21.$^{33}$ Different addresses can be used, of course, but they must match  33 LAN operation in LCS mode can use CTC definitions in the z/OS IODF. This is a carryover from earlier LAN  implementations. Chapter 7.
