| Description | A unique value, for each Energy Object.
If an implementation of the ENERGY-AWARE-MIB module is
available in the local SNMP context, then the same index,
eoIndex, as the one in the ENERGY-AWARE-MIB MUST be
assigned for the identical Energy Object. In this case,
entities without an assigned value for eoIndex cannot be
indexed by the eoPowerStateTable.
If there is no implementation of the ENERGY-AWARE-MIB
module but one of the ENTITY MIB module is available in
the local SNMP context, then the same index of an entity
MUST be chosen as assigned to the entity by object
entPhysicalIndex in the ENTITY MIB module. In this case,
entities without an assigned value for entPhysicalIndex
cannot be indexed by the eoPowerStateTable.
If neither the ENERGY-AWARE-MIB module nor of the ENTITY
MIB module are available in the local SNMP context, then
this MIB module may choose identity values from a further
MIB module providing entity identities. In this case the
value for each eoPowerIndex must remain constant at least
from one re-initialization of the entity's network
management system to the next re-initialization.
In case that no other MIB modules have been chosen for
providing entity identities, Power States can be reported
exclusively for the local device on which this table is
instantiated. Then this table will have a single entry
only and an index value of 0 MUST be used. |
