Operation Manual – SNMP-RMONH3C S3100 Series Ethernet Switches Chapter 1 SNMP Configuration1-2z Specifying MIB view that a community can access.z Set the permission for a community to access an MIB object to be read-only orread-write. Communities with read-only permissions can only query the switchinformation, while those with read-write permission can configure the switch aswell.z Set the basic ACL specified by the community name.1.1.3 Supported MIBsAn SNMP packet carries management variables with it. Management variable is usedto describe the management objects of a switch. To uniquely identify the managementobjects of the switch, SNMP adopts a hierarchical naming scheme to organize themanaged 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 pathstarting from the root.A261521121BFigure 1-1 Architecture of the MIB treeThe management information base (MIB) describes the hierarchical architecture of thetree 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 ofnumbers {1.2.1.1}. The number string is the object identifier (OID) of the managedobject.The common MIBs supported by switches are listed in Table 1-1.
