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 included
• Modifying the default access line to give read-only access to the entire MIB tree for the public community. Server Administrator
looks for the following line: access notConfigGroup "" any noauth exact systemview none none
• If Server Administrator finds the above line, it modifies the line as: access notConfigGroup "" any noauth exact
all none none
NOTE: To ensure that Server Administrator is able to modify the SNMP agent configuration for providing proper
access to systems management data, it is recommended that any other SNMP agent configuration changes be made
after installing Server Administrator.
Server Administrator SNMP communicates with the SNMP agent using the SNMP Multiplexing (SMUX) protocol. When Server
Administrator SNMP connects to the SNMP agent, it sends an object identifier to the SNMP agent to identify itself as a SMUX
