Supported Mibs - 3Com WX3000 Series Operation Manual

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.
Specifying MIB view that a community can access.
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 device information, while those with
read-write permission can configure the device as well.
Set 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
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.
