Xmodulo shows you how to configure SNMPv3 in Ubuntu, CentOS and Cisco

Simple Network Management Protocol (SNMP) is a widely used protocol for gathering information about what is going on within a device. For example, CPU and RAM usage, load on a server, traffic status in a network interface, and many other interesting properties of a device can be queried using SNMP.

Currently, three versions of SNMP are available: v1, v2c and v3. SNMP v1 and v2c can be easily configured, which has been discussed in a previous article. SNMPv3 adds some additional features, including authentication and encryption schemes (e.g., MD5, SHA, AES and DES). This makes SNMPv3 more secure and advisable while you run SNMP queries over the Internet.

SNMPv3 configuration is a bit different compared to SNMP v1 or v2c. The following sections explain in detail how the configuration is done.
