I have 2 mainframes each with a unique NETID. Each mainframe has a fep. I run MSNF ( multiple systems networking facility ) between the FEP's. I was told that if I turn on APPN on my VTAM's, I could set up APPN nodes and run MSNF across CIPs instead of the FEP's.
My question is will I have any unexpected problems with the MSNF connections, other SNI connections, or anything already running on the NCP / FEP just by turning on APPN.
