52 Configuring IT Assistant to Monitor Your Systems

Although the

Get Community

name affects read-only information retrieved by IT Assistant from

managed systems, such as the results of discovery, status polling, and alert logs, Tom wants to limit

access to this data. Therefore, he changes the default

Get Community

name (

public

) to a name

known only to him and his system administrators.

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.

• Enter 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.

• Enter time-out and retry values for the SNMP discovery range. In Tom’s type of network, the

default values are usually good choices.

In Step 4 of the wizard, configure the CIM parameters to be used during discovery.

Since Tom also has systems running Windows, he needs to configure CIM.

•Make sure

Enable CIM Discovery

is selected.

•In

Domain/User Name

, enter the same name that you used to configure CIM on the

managed system.

• Enter the same

Password

that you used for the CIM password on the managed system.

In Step 5 of the wizard, choose what action IT Assistant will take upon completion of the wizard.

In Step 6 of the wizard, review your selections and choose

Finish

to complete the wizard or

Back

change your selections.
