SNAX/XF Passthrough
For SNAX/XF passthrough, the SNA host LU is always the primary LU.
Sessions Initiated by SNA Host LU
The SNA host application sends a BIND request to a SNAX/XF gateway LU, as shown
in Figure A-6.
Sessions Initiated by SNA Peripheral Node LU
The sequence of events is shown in Figure A-7. For more information, see Processing
Messages from SNA Peripheral Nodes on page 5-2.
