1.11 SNMP Management

ROS supports Simple Network Management Protocol Version 3 (SNMPv3). This protocol provides secure access to devices by a combination of authentication and encrypting packets over the network. The security features provided are:

•message integrity - ensuring that a packet has not been tampered with in-transit

•authentication – determining the message is from a valid source

•encryption – scrambling 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 that is set up 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 security level will determine which security mechanism is employed when handling an SNMP packet.

Note the following about SNMPv3 protocol:

•each user belongs to a group

•a group defines the access policy for a set of users

•an access policy defines what SNMP objects can be accessed for: reading, writing and creating, notifications

•a group determines the list of notifications its users can receive

•a group also defines the security model and security level for its users.

1.11.1SNMP Users

These parameters provide the ability to configure users for the local SNMPv3 engine. Note that, if employed security level is SNMPv1 or SNMPv2, user Name represents a community name for authentication or sending traps. Up to 32 entries can be configured.
