functions as password. It can limit accesses made by SNMP NMS to SNMP agent. You
can perform the following community name-related configuration.
z
Specifying MIB view that a community can access.
z
Set the permission for a community to access an MIB object to be read-only or
read-write. Communities with read-only permissions can only query device
information, while those with read-write permission can configure devices as well.
z
Set the basic ACL specified by the community name.
1.1.3 Supported MIBs
An SNMP packet carries management variables with it. Management variable is used
to describe the management objects of a device. To uniquely identify the management
objects of the device, SNMP adopts a hierarchical naming scheme to organize the
managed objects. It is like a tree, with each tree node representing a managed object,
as shown in Figure 1-1. Each node in this tree can be uniquely identified by a path
starting from the root.

Figure 1-1 Architecture of the MIB tree
The management information base (MIB) describes the hierarchical architecture of the
tree and it is the set defined by the standard variables of the monitored network devices.
In the above figure, the managed object B can be uniquely identified 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 Table 1-1.
