Configuring the SNMP Agent on Systems Running Supported SUSE Linux Enterprise Server
Operating Systems
Server Administrator uses the SNMP services provided by the ucd-snmp or net-snmp agent. You can
configure the SNMP agent to enable SNMP access from remote hosts, 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: On SUSE Linux Enterprise Server (version 9), the SNMP agent configuration file is located at
/etc/snmpd.conf. On SUSE Linux Enterprise Server (version 10), the SNMP agent configuration file is located at
/etc/snmp/snmpd.conf.
NOTE: See your operating system documentation for additional details about SNMP configuration.
