Activating NCPROUTE selective traces
The NCPROUTE selective traces are all activated as trace options specified in the OPTIONS statement for an NCP client in the NCPROUTE GATEWAYS data set. Selective tracing means a different trace level can be specified for each NCP client. To assist in problem isolation, a particular NCP client can be selected for tracing.
The keyword on the OPTIONS statement that controls selective
tracing for an NCP client is trace.level. The value
that follows this keyword indicates the trace level to be used.
- Value
- Meaning
- 0
- Does not activate any traces.
- 1
- Activates tracing of actions by the NCPROUTE server.
- 2
- Activates tracing of all packets sent or received.
- 3
- Activates tracing of actions, packets sent or received, and packet history. Circular trace buffers are used for each interface to record the history of all packets traced. This history is included in the trace output whenever an interface becomes inactive.
- 4
- Activates tracing of actions, packets sent or received, packet history, and packet contents. The RIP network routing information is included in the trace output.
Restriction: The selective traces must be defined
prior to activation of an NCP client or prior to starting the NCPROUTE
cataloged procedure.
See the z/OS Communications Server: IP Configuration Reference for more information about the GATEWAYS data set and the GATEWAY and OPTIONS statements.
For example, the following command would activate tracing
of actions, packets sent or received, packet history, and packet contents:
options trace.level 4
