ITA communicating with Linux systems:

SNMP is required on the Linux system for discovery, status polling and

inventory.

Dell software updates are done through an SSH session and secure FTP

and root level permissions/credentials are required for this discrete action

and asked for when the action is setup or requested. Credentials from the

discovery range are not assumed.

ITA

communicating with Windows systems:

For servers (systems running Windows Server operating systems), the

system may be configured with either or both of SNMP and CIM for

discovery by ITA. Inventory requires CIM.

Software updates, as in Linux, are not related to discovery and polling and

the protocols used.

Using Administrator level credentials asked for at the time the update is

scheduled or performed, an administrative (drive) share is established to a

drive on the target system, and file(s) copying from somewhere (possibly

another network share) is done to the target system. WMI functions are

then invoked to execute the software update.

As Server Administrator is not installed on Clients/Workstations, so CIM

discovery is used when the target is running the OpenManage Client

Instrumentation.

For many other devices such as network printers, the standard is still

SNMP to communicate with (primarily discover) the device.

Devices such as EMC storage have proprietary protocols. Some

information about this environment can be gathered from looking at the

ports used tables in the OpenManage documentation.

Are there any plans for SNMP v3 support?

No, there are no plans for SNMP v3 support.
