SNMP NMS and SNMP agent. Community name functions as password. It can limit accesses made by SNMP NMS to SNMP agent. You can perform the following community name-related configuration.

zSpecifying MIB view that a community can access.

zSet 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 device information, while those with read-write permission can configure the device as well.

zSet the basic ACL specified by the community name.

Supported MIBs

An SNMP packet carries management variables with it. Management variable is used to describe the management objects of the 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.

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 devices are listed in Table 1-1.
