To check the snmpd agent and stop it (if necessary): If it is, you must stop the snmpd agent so you can create the configuration file. You must check if the snmpd agent is running. NOTE: You should configure the nf file before you start the snmpd daemon. The configuration file for the snmpd agent is installed in /etc/snmp/nf. The snmpd binary is installed in the directory /usr/sbin/snmpd. The Linux RPM for net-snmp includes the snmpd (Net-SNMP agent) binary as follows: 
After you have verified and installed all the packages, you can create the net-snmp configuration file and start the snmp service (agent).If one or more of these packages are missing you can run the appropriate command from the following commands:.Ensure that the output of this command includes each RPM listed above.Enter one of the following at the prompt:.To continue with the steps in this section, you must verify the presence of these RPMs on the server that SL1 will monitor.

SL1 includes multiple default Dynamic Applications for the Net-SNMP agent. If Net-SNMP is correctly installed and configured on a Linux device, SL1 can automatically query the device and collect data.
