SNA IMF Programmer's Reference Manual: HP 3000 MPE/iX Computer Systems![]() Appendix D Differences Between IMF/3000 and SNA IMF/V |
|
Table of Contents If you are migrating from IMF/3000 to SNA IMF/V on an MPE V system, you may find the information in this Appendix helpful. IMF/3000 uses either BSC or SDLC protocol in a Node Type 1 environment. SNA IMF uses only SDLC protocol in a Node Type 2 environment.

This Appendix compares and contrasts IMF/3000 with SNA IMF/V in these areas:
