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 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: See your operating system documentation for additional details about
SNMP configuration.
SNMP Agent Access Control Configuration
The management information base (MIB) branch implemented by Server
Administrator is identified by the 1.3.6.1.4.1.674 OID. Management station
applications must have access to this branch of the MIB tree to manage
systems running Server Administrator.
For supported 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 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 /etc/snmp/snmpd.conf SNMP agent
configuration file 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:
