Management Features

Management features of SNMPv3 allow you to specify who will receive notifications and to define MIB views that users in different groups can access:

• Notification—Message that informs you of a status change; the equivalent of a trap in SNMPv1.
• View—Definition of the management information that is available: read, write, or notification. Predefined views are available for each group:
  • everything—Includes all MIBs associated with the router, except the packetMirror MIB
  • user—Includes all MIBs associated with the router, except the packetMirror MIB and standard and enterprise MIBs used to configure SNMP operation
  • nothing—Excludes all MIBs
  • mirrorAdmin—Includes the packetMirror MIB
• User—An individual who requires access to the router. The router may provide authentication and privacy for the user through SNMPv3. Each user is associated with a group.
• Group—A set of users with the same access privileges to the router. Three predefined groups are available: admin, public, and private. Table 18 shows the security levels and views associated with these groups.
