Configuring Your System To Send SNMP Traps To A Management Station
Server Administrator generates SNMP traps in response to changes in the status of sensors and other
monitored parameters. You must configure one or more trap destinations on the system running Server
Administrator for SNMP traps to be sent to a management station.
1. Open the Computer Management window.
2. Expand the Computer Management icon in the window, if necessary.
3. Expand the Services and Applications icon and click Services.
4. Scroll down the list of services until you find SNMP Service, right-click SNMP Service , and then click
Properties.
The SNMP Service Properties window appears.
5. Click the Traps tab to add a community for traps or to add a trap destination for a trap community.
a. To add a community for traps, type the community name in the Community Name box and click
Add to list, which is located next to the Community Name box.
b. To add a trap destination for a trap community, select the community name from the
Community Name drop-down box and click Add under the Trap Destinations box.
The SNMP Service Configuration window appears.
c. In the Host name, IP or IPX address box, type the trap destination, Add.
The SNMP Service Properties window appears.
6. Click OK to save the changes.
Configuring The SNMP Agent On Systems Running Supported Red Hat Enterprise Linux
Server Administrator uses the SNMP services provided by the net-snmp SNMP agent. You can configure
the SNMP agent to change the community name, enable Set operations, and send traps to a
management station. To configure your SNMP agent for proper interaction with management
applications such as IT Assistant, perform the procedures described in the following sections.
NOTE: For additional details on SNMP configuration, see the operating system documentation.
SNMP Agent Access Control Configuration
The management information base (MIB) branch implemented by Server Administrator is identified by the
Object Identifier (OID) 1.3.6.1.4.1.674. Management applications must have access to this branch of the
MIB tree to manage systems running Server Administrator.
For Red Hat Enterprise Linux and VMware ESXi 4.0 operating systems, the default SNMP agent
configuration gives read-only access for the public community only to the MIB-II system branch
(identified by the 1.3.6.1.2.1.1 OID) of the MIB tree. This configuration does not allow management
applications to retrieve or change Server Administrator or other systems management information
outside of the MIB-II system branch.
Server Administrator SNMP Agent Install Actions
If Server Administrator detects the default SNMP configuration during installation, it attempts to modify
the SNMP agent configuration to give read-only access to the entire MIB tree for the public community.
Server Administrator modifies the SNMP agent configuration file
/etc/snm, p/snmpd.conf by:
• Creating a vew to the entire MIB tree by adding the following line if it does not exist: view all
