IMPORTANT:
An NMS and an SNMP agent must use the same SNMP version to communicate with each other.
MIB and view-based MIB access control
A MIB view represents a set of MIB objects (or MIB object hierarchies) with certain access privilege and
is identified by a view name. The MIB objects included in the MIB view are accessible while those
excluded from the MIB view are inaccessible.
A MIB view can have multiple view records each identified by a view-name oid-tree pair.
You can control access to the MIB by assigning MIB views to SNMP groups or communities. The
relationship between an NMS, agent and MIB is shown in
Figure 35 .
Figure 35 Relationship between an NMS, agent and MIB
A MIB stores variables called “nodes” or “objects” in a tree hierarchy and identifies each node with a
unique OID. An OID is a string of numbers that describes the path from the root node to a leaf node. For
example, the object B in Figure 36 is uniquely identified by the OID {1.2.1.1}.

Configuring SNMP basic parameters
SNMPv3 differs from SNMPv1 and SNMPv2c in many aspects. Their configuration procedures are
described in separate sections.
