Goal

The goal of this document is to explain how to change the SNMP community string on compute nodes, cell nodes and their associated ILOMs within an Engineered system.  This is particularly useful when needing to change the string from the default "public" to meet security requirements (such as addressing CVE-1999-0517).

  

While changing the community string does not explicitly require the cell, cluster and/or database to be down, it is recommended that the changes be made during a maintenance window.
After accomplishing the following steps it is important to test the configuration thoroughly to ensure there is no impact to EM monitoring, Automated Service Requests, etc.   Performing these changes on a test system first is highly recommended.
