Object
This object specifies whether ifIndex values persist across
reinitialization of the device.
ifIndex persistence means that the mapping between the ifDescr
object values and the ifIndex object values will be retained
across reboots.
Applications such as device inventory, billing, and fault
detection depend on the maintenance of the correspondence
between particular ifIndex values and their interfaces. During
reboot or insertion of a new card, the data to correlate the
interfaces to the ifIndex may become invalid in absence of
ifIndex persistence feature.
ifIndex persistence for an interface ensures ifIndex value for
the interface will remain the same after a system reboot. Hence,
this feature allows users to avoid the workarounds required for
consistent interface identification across reinitialization.
The allowed values for this object are either enable or disable.
global value is not allowed.

Enumeration
Type Description
This textual convention is used to define the state of ifIndex
Persistence for both global as well as interface level.
The global object, cieIfIndexGlobalPersistence can have two
state of ifIndex Persistence i.e. either enable or disable. At
interface level, the object cieIfIndexPersistenceControl can
take all the three values enable/disable/global.
