Views control the access to a managed object. The total MIB of a 7705 SAR router can be viewed as a hierarchical tree. When a view is created, either the entire tree or a portion of the tree can be specified and made available to a user to manage the objects contained in the subtree. Object identifiers (OIDs) uniquely identify managed objects. A view defines the type of operations allowed, such as read, write, or notify.
OIDs are organized in a hierarchical tree with specific values assigned to different organizations. A view defines a subset of the agent’s managed objects controlled by the access rules associated with that view.
Predefined views are available that are particularly useful when configuring SNMPv1 and SNMPv2c.
The SNMP agent associates SNMPv1 and SNMPv2c community strings with an SNMPv3 view.
