Section 5.7
Managing SNMP
ROS supports versions 1, 2 and 3 of the Simple Network Management Protocol (SNMP), otherwise referred to
as SNMPv1, SNMPv2c and SNMPv3 respectively. SNMPv3 provides secure access to the devices through a
combination of authentication and packet encryption over the network. Security features for this protocol include:
Feature Description
Message Integrity Makes sure that a packet has not been tampered with in-transit.
Authentication Determines if the message is from a valid source.
Encryption Encrypts the contents of a packet to prevent it from being seen by an unauthorized source.
SNMPv3 provides security models and security levels. A security model is an authentication strategy setup for
a user and the group in which the user resides. A security level is a permitted level of security within a security
model. A combination of a security model and level will determine which security mechanism is employed when
handling an SNMP packet.
