36 Configuring IT Assistant to Monitor Your Systems
Information on the Managed System Needed for Optimal SNMP Configuration
For every system to be discovered and managed using SNMP protocol, ensure that:
• SNMP is installed.
• The name or IP address for the IT Assistant system is in the list under the
SNMP Service Properties
window → Security tab → Accept SNMP packets from these hosts radio button. This value needs to
be configured on the managed system.
• If managed systems are going to send traps to IT Assistant, the host name or IP address of the
IT Assistant system must be listed as the
Trap destination on the Traps tab of the SNMP Service
Properties
window.
• Valid community names must be assigned on the
Traps and Security tabs as appropriate in the
SNMP Service Properties window.
The two community names that are to be set up are the Get (or read) community name and the Set (or
write) community name. The read community name, which is sometimes labeled read only, allows
IT Assistant to read information from the managed system, while the write community name,
sometimes labeled read write, allows IT Assistant to read and write information to the managed system.
NOTE: Community names are case sensitive.
NOTE: Although you can set up just one community name as both read and read/write, it is advisable to create a
separate name for each to allow restricted access to the write action.
The community names that you assign for SNMP for managed systems in the operating system must also
be recorded in IT Assistant when you set up SNMP discovery ranges.
In the Discovery Range dialog box under the protocols section, make sure that the Get (or read) and Set
(or write) community names of all of the managed systems are entered. If there is more than one
community name per field, separate each community name with a comma.
Configuring CIM for Manageability
Depending on your network environment, configuring CIM may be a required task. CIM is the preferred
systems management protocol for newer client instrumentation and is required for Dell systems
instrumented with OMCI version 7.x. CIM is also used for performing remote Windows
software updates.
In her small-to-medium size network, Jane must install, enable, and configure CIM to be able to manage
client systems running the latest Client Instrumentation (OMCI 7.x). Although Tom’s group of
managed systems are made up entirely of servers, he will also install and enable CIM. Generally, CIM
should be enabled if your enterprise includes any managed system running a Microsoft
®
Windows
®
operating system.
