Configuring Dell OpenManage IT Assistant to Monitor Your Systems 115
NOTE: Community names entered in the SNMP Get and Set community
name fields for the managed system’s operating system must match the
Get Community and Set Community names assigned in IT Assistant.
• Tom enters a case-sensitive value for the Set Community name.
Tom’s considerations:
The
Set Community name is a read-write password that allows access to a
managed system. SNMP agents running on the managed system use this
password for authentication when actions are attempted on the system,
including shutting down, configuring action alerts, and updating software.
NOTE: Although Dell server instrumentation has an authentication layer
above the SNMP Set community name (which requires a host name and
password), many SNMP agents do not. Agents without this added
security layer allow any user who knows the SNMP Set community
name to gain control of the managed system.
Tom chooses a Set Community name that matches the SNMP Set
community value on the system he is managing. He also makes sure
the name he chooses follows the secure password standards in place
across his enterprise.
NOTE: If you want to specify more than one SNMP Get or Set
community name in an individual discovery range (for example, one
community name for each IP subnet range), separate your community
names with commas.
NOTE: IT Assistant only uses SNMP sets to power cycle systems if the
Server Administrator remote command line is not available. If SNMP
sets are not required for this purpose, do not enter an SNMP set
community name in the discovery wizard.
• Tom enters time-out and retry values for the SNMP discovery range.
6 In step 4 of the wizard, Tom configures the CIM parameters to be used
during discovery.
Since Tom also has systems running Windows, he needs to configure
CIM.
• Tom ensures
Enable CIM Discovery is selected.
NOTE: Ensure that CIM is configured for Hyper-V and Hyper-V Server to
enable full virtualization support.
