After upgrading UIM, we lost support for AES-256 support in profiles of the snmpcollector. The probe documentation describes needing to add extra AES policy files to allow the AES-192 and AES-256 protocols. The documentation describes this:
However, it is noted that the jre6 folder isn't the only folder or isn't in the jre directory at all. Other jre versions are in this location.
Release : 9.0.2
Component : UNIFIED INFRASTRUCTURE MGMT
java_jre probes are upgraded in newer versions of UIM. Newer extension policy files will need to be added.
Identify the correct version of java_jre and download the extension policy files for your version of java. Following the documentation and replacing the documented version with the version in your environment should resolve this for you.
