The scope of the discovery contains the IBM Tivoli Network Manager IP Edition V3.9 (ITNM) server
and the gateway trace file shows that this is being used successfully as the correct NcpServerEntity.
However, the isolated suppression method is not working. What would cause this?

A.
The ITNM server is not being directly polled for status.

B.
The ITNM server is not connected to the rest of the topology.

C.
There was no SNMP access to the ITNM server so the IP address is not known.

D.
The Root Cause Analysis plug-in has not been explicitly configured to use the ITNM server.
