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 the switch
information, while those with read-write permission can configure the switch 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 switch. To uniquely identify the management
objects of the switch, 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 (OID) of the managed
object.
The common MIBs supported by switches are listed in
Table 1-1.
