Configuring the SNMP Agent on Systems Running Supported Red Hat Enterprise Linux
Operating Systems
Server Administrator uses the SNMP services provided by the ucd-snmp or 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 and Array Manager, perform the procedures described in the following sections.
NOTE: See your operating system documentation for additional details on SNMP configuration.
SNMP Agent Access Control Configuration
The management information base (MIB) branch implemented by the Instrumentation Service is
identified by the OID, 1.3.6.1.4.1.674.10892.1. Management applications must have access to this
branch of the MIB tree to manage systems running the Instrumentation Service.
For Red Hat Enterprise Linux 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 OID,
1.3.6.1.2.1.1) of the MIB tree. This configuration does not allow management applications to retrieve or
change Instrumentation Service and other systems management information outside of the MIB-II
"system" branch.
If Server Administrator detects this 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. It does
this by changing the SNMP agent configuration file, /etc/snmp/snmpd.conf, in two ways.
The first change is to create a view to the entire MIB tree by adding the following line if it does not exist:
view all included .1
The second change is to modify 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 line above, it modifies the line so that it reads:
access notConfigGroup "" any noauth exact all none none
