name can limit access to SNMP Agent from SNMP NMS, functioning as a password.
You can define the following features related to the community name.
z Define MIB view of subsets of all MIB objects which a community can access.
z Set read-only or read-write right to access MIB objects for the community. The
read-only community can only query device information while the read-write
community can configure the device.
1.1.3 MIBs Supported by the Device
The management variable in the SNMP packet describes management objects of a
device. To uniquely identify the management objects of the device in SNMP messages,
SNMP adopts the hierarchical naming scheme to identify the managed objects. It is like
a tree, and each tree node represents a managed object, as shown in the figure below.
Thus the object can be identified with the unique path starting from the root.

Figure 1-1 Architecture of the MIB tree
The management information base (MIB) is used to describe the hierarchical
architecture of the tree and it is the set defined by the standard variables of the
monitored network device. In the above figure, the managed object B can be uniquely
specified by a string of numbers {1.2.1.1}. The number string is the Object Identifier of
the managed object.
The common MIBs supported by the system are listed in the following table.
