Configure SNMP Service on Oracle Linux

Configure SNMP Service on Oracle Linux/CentOS/Red Hat

SNMP stands for Simple Network Management Protocol, It is use to collect the behaviors of Network Devices through IP and send the Network Devices Behaviors information's to NMS (Network Management System) for example: Open Manager, Zenoss and etc. The Ports of SNMP (Simple Network Management Protocol) are 161 udp and 162 udp.
Here we are configuring the SNMP (Simple Network Management Protocol) service on Oracle Linux 6.5, During the installation of Oracle Linux 6.5 SNMP (Simple Network Management Protocol) service has installed. To check the status of SNMP (Simple Network Management Protocol) service type the below command.

service snmpd status

To Configure the SNMP (Simple Network Management Protocol) service edit the file "snmpd.conf" that available in directory "/etc/snmp/snmpd.conf" by use of vi editor.

vi /etc/snmp/snmpd.conf

Edit the below lines in file "snmpd.conf" and remove all inside the file before edit, you can also create new file "snmpd.conf" and replace with the original file "snmpd.conf". Replace your Network addresses and Community name that you configure in Network Management System "NMS" means Open Manager, Zenoss and etc. you can also set specific Network Management System "NMS" IP for example: 172.20.1.89 not complete network for example: 172.20.1.0/16.

# Allow Systems Management Data Engine SNMP to connect to snmpd using SMUX

To Enable and Start the SNMP (Simple Network Management Protocol) service permanently on second, third, fourth and fifth Linux interface levels type the below command.

chkconfig --level 2345 snmpd on

service snmpd start

To check the status of SNMP (Simple Network Management Protocol) service type the below command.

service snmpd status

This is complete configuration of SNMP (Simple Network Management Protocol) on client machine of Linux Base Operating System. In our case the machine is Oracle Linux 6.5. Oracle Linux compiled from Red Hat Enterprise Linux source code therefore you can use this SNMP (Simple Network Management Protocol) configuration on Red Hat and CentOS Linux (Community Supported Means Open Source).
