The SNMP agent is preinstalled on this server and runs on Oracle ILOM, so all SNMP management occurs through Oracle ILOM. To manage the server using SNMP, you must install an SNMP client application (for example, HMP, Openview, or Tivoli).
The SNMP agent is active only on the Active SP. In the event of failover, the SNMP agent is restarted on the newly assigned Active SP.
