Verifying TCPIP.DATA statement values in the native MVS™ environment

To display which TCPIP.DATA statement values are being used and where they are being obtained from, use trace resolver output. You can obtain trace resolver output at your TSO screen by issuing the following TSO commands:

alloc f(systcpt) dsn(*)
READY
netstat up
READY
free f(systcpt)
READY

Tip: When directing trace resolver output to a TSO terminal, define the screen size to be only 80 columns wide. Otherwise, trace output is difficult to read.

For further information on the trace resolver facility and interpreting its output, see z/OS Communications Server: IP Diagnosis Guide.
