The InfiniBand switches that are installed in the racks of an Engineered System are updated to send traps to the Gateway and a set of SSH/SCP keys is created to allow password-less login from the monitoring agent to the nm2user on the switch.
The SSH/SCP keys for Exadata and SuperCluster systems are configured at discovery time. For the other systems, these are created manually by the installation engineer during the implementation prior to the target discoveries.
