Names for the lines and PUs are generated using the naming convention sssssnnn, where:

• sssss

  Is the value specified by line_seed_char or pu_seed_char on the AUTOGEN operand.

  • If you specify a single-character seed value, VTAM adds the channel unit address coded on the CUADDR operand on the PORT definition statement in the XCA major node to the single-character seed value, and then adds a sequential number to the end of the name.
    For ATM native connections: Four zeros are used in place of the CUA coded on the CUADDR operand.
  • If you specify a seed value greater than a single character, VTAM uses the multiple-character seed value you specify, and then adds a sequential number to the end of the name.
  • If you do not specify a seed character, VTAM uses the default (O for LINE definition statements; Q for PU definition statements).

  nnn

  Is a sequential hexadecimal number created by VTAM (X'0'–X'FFF').

For example, if you want to enable VTAM to generate 15 lines and physical units where each LINE name begins with L and each PU name begins with P, code the following statements:

PORT2    PORT  MEDIUM=RING,            TOKEN-RING
               SAPADDR=4,              SERVICE ACCESS POINT ADDRESS
               ADAPNO=1,               ADAPTER NUMBER
               CUADDR=BC0              CHANNEL UNIT ADDRESS
