TCP/IP subagent trace
When requests for MIB variables supported by the TCP/IP subagent fail with an indication that the variable is not supported (noSuchName or noSuchObject), one possibility is that the TCP/IP subagent was unable to connect to the SNMP agent.
Figure 1 illustrates a scenario
where the subagent is unable to connect because the password it is
using is not accepted by the SNMP agent. (The password used by the
subagent is defined or defaulted on the SACONFIG statement in the
TCP/IP profile.) The following traces were obtained with SNMP agent
traces set to 15 and the subagent traces (as set on the ITRACE profile
statement) set to 3.
