Entity MIB Objects Description Syntax An enumerated value that provides an indication of the general hardware type of a particular physical entity. There are no restrictions as to the number of entPhysicalEntries of each entPhysicalClass, which must be instantiated by an agent. Integer Table 7: Possible values for PhysicalClass Values other (1) unknown (2) chassis (3) backplane (4) container (5) powerSupply (6) fan (7) sensor (8) Description The physical entity class is known, but does not match any of the supported values. The physical entity class is unknown to the agent. The physical entity class is an overall container for networking equipment. Any class of physical entity except a stack may be contained within a chassis, and a chassis may be contained only within a stack. The physical entity class is a device for aggregating and forwarding networking traffic, such as a shared backplane in a modular ethernet switch. Note that an agent may model a backplane as a single physical entity, which is actually implemented as multiple discrete physical components (within a chassis or stack). The physical entity class is capable of containing one ore more removable physical entities, possibly of different types (such as a chassis slot or daughter-card holder). For example, each (empty or full) slot in a chassis will be modeled as a container. Note that all removable physical entities should be modeled within a container entity, such as field-replaceable modules, fans, or power supplies. Note that all known containers, including empty containers, should be modeled by the agent. The physical entity class is a power-supplying component. The physical entity class is a fan or other heat-reduction component. The physical entity class is a sensor, such as a temperature sensor within a router chassis.
