Object
column r/w
OctetString
This object is an 'alias' name for the physical entity, as
specified by a network manager, and provides a non-volatile
'handle' for the physical entity.
On the first instantiation of a physical entity, the value
of entPhysicalAlias associated with that entity is set to
the zero-length string. However, the agent may set the
value to a locally unique default value, instead of a
zero-length string.
If write access is implemented for an instance of
entPhysicalAlias and a value is written into the instance,
the agent must retain the supplied value in the
entPhysicalAlias instance (associated with the same physical
entity) for as long as that entity remains instantiated.
This includes instantiations across all
re-initializations/reboots of the network management system,
including those resulting in a change of the physical
entity's entPhysicalIndex value.
