Verifying TCPIP.DATA statement values in the z/OS UNIX 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 by issuing the following z/OS® UNIX shell commands:

export RESOLVER_TRACE=stdout
netstat -u
set -A RESOLVER_TRACE

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