Configuring Dell OpenManage IT Assistant to Monitor Your Systems 93
order to correctly send these traps, the operating system’s SNMP service must
be configured with one or more trap destinations that correspond to the
system where IT Assistant is installed.
Details on Configuring the SNMP Service
For detailed information about SNMP configuration for the IT Assistant
system and for all supported managed system, operating systems, see
"Configuring the SNMP Service" on page 258.
Configuring SNMP on Systems You Want to Manage
In addition to having the SNMP service installed and running on the
IT Assistant system, each managed system’s operating system must have
the SNMP service or daemon configured.
SNMP Best Practices
When configuring SNMP, adhere to the following requirements:
• Use a host name or a static IP address for the IT Assistant system.
• On all managed systems, configure the static IP address or host name
as the SNMP trap destination. If you use a host name as the SNMP trap
destination (the IT Assistant system name), you must correctly configure
name resolution on your network.
• Ensure that
Get and Set community names for SNMP are different.
• When assigning community names to managed systems, keep the total
number of different community names low. The fewer community names,
the easier it will be to manage your network.
Information on the Managed System Needed for Optimal SNMP Configuration
For every system (running the Windows operating system) to be discovered
and managed using SNMP protocol, ensure that SNMP is installed and
properly configured.
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.
