entStateUsage
Module: ENTITY-STATE-MIB
OID (symbolic): ENTITY-STATE-MIB::entStateUsage
OID (numeric): 1.3.6.1.2.1.131.1.1.1.4
Node type: OBJECT-TYPE
Type: EntityUsageState
Access: read-only
Description: The usage state for this entity.
This object refers to an entity's ability to service more physical entities in a containment hierarchy. A value of 'idle' means this entity is able to contain other entities but that no other entity is currently contained within this entity.
A value of 'active' means that at least one entity is contained within this entity, but that it could handle more. A value of 'busy' means that the entity is unable to handle any additional entities being contained in it.
Some entities will exhibit only a subset of the usage state values. Entities that are unable to ever service any entities within a containment hierarchy will always have a usage state of 'busy'. Some entities will only ever be able to support one entity within its containment hierarchy and will therefore only exhibit values of 'idle' and 'busy'.
What is entStateUsage?
This object indicates how much capacity this entity's containment slot still has for holding other entities, ranging from idle through active to busy. Admins check it when planning to add new sub-components, such as modules or ports, to see whether a chassis slot or card still has room. For example, entStateUsage reporting busy on a chassis slot tells an admin that slot is already at full capacity and cannot accept another card.
