Telnet Component Trace data

To help associate a Component Trace entry with a particular client, the following two Component Trace fields contain data unique to Telnet:

CID: The connection ID for the connection. This is equivalent to the connection ID output from the connection display command.
USER: The LUname associated with the client, after it has been assigned. Prior to LUname assignment, this field might be null or contain the TCP procedure name. The LUname is not set until after the completion of the Telnet handshake.

Use these fields in Component Trace formatting to limit the records to be displayed. For example, if you want Telnet records for a client connection ID X'021F' with the LUName TCPM1011, code the following IPCS command:

CTRACE COMP(SYSTCPIP) SUB((proc_name)) FULL JOBLIST (TCPM1011)
OPTIONS((TELNET,CID(X'0000021F')))

Tip: Some of the records pertinent to the connection are not shown when the output is restricted by the CID and USER options. However, it is often helpful to use the output produced by these filters as a starting point.
