Configuring SNMPv3

SNMPv3 is the current standard version of SNMP defined by the Internet Engineering Task Force (IETF).

It provides three important security features:
•

Message integrity to ensure that a packet has not been tampered with in transit

•

Authentication to verify that the message is from a valid source

•

Encryption of packets to prevent unauthorized access

Configuring SNMPv1/v2c with SNMPv3

SNMP version 1 (SNMPv1) is the initial implementation of the SNMP protocol. SNMPv1 operates over

protocols such as User Datagram Protocol (UDP).

SNMPv2c includes improvements in performance, confidentiality, and manager-to-manager

communications over SNMPv1, however it uses the simple-community based security scheme of

SNMPv1.
