Disabling zERT discovery

You turn the zERT discovery function off in the TCP/IP stack by specifying the GLOBALCONFIG NOZERT parameter in the TCP/IP profile data set.

Guideline: This is the default behavior.

Results: Disabling zERT discovery also disables zERT aggregation.

Disabling zERT discovery causes the TCP/IP stack to not monitor the cryptographic characteristics of TCP and Enterprise Extender connections that terminate at the stack.

Results: If you dynamically disable zERT discovery using VARY OBEYFILE, any previous information collected by zERT discovery and aggregation is discarded.

For more information on disabling zERT, see GLOBALCONFIG statement in z/OS Communications Server: IP Configuration Reference.
