To find what your stack is really running with, take a SVC dump of the TCPIP
address space, then with IPCS,
- allocate userid.IPCS.PRINT (or something similar) RECFM=VBA,LRECL=133
- TSO alloc fi(ipcsprnt) da('userid.IPCS.PRINT')
- Change IPCS defaults to PRINT TERMINAL
- Issue IPCS command: TCPIPCS PROFILE
- Issue IPCS command: REPORT IPCSPRNT
Shows a lot of useful (and, at times, surprising) information. The info
may help you build accurate an accurate routing table.
