cienaCesPmInstanceInterfaceId2
Module: CIENA-CES-PM
OID (symbolic): CIENA-CES-PM::cienaCesPmInstanceInterfaceId2
OID (numeric): 1.3.6.1.4.1.1271.2.3.1.2.2.1.1.21
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-create
Description: InterfaceId2 in the PM instance acts as a secondary identifying index in cases where the cienaCesPmInstanceInterfaceId object cannot uniquely identify the interface associated with the PM instance.
For interfaces which do not utilize this secondary object, the value of this object is zero and unused during new row creation.
For interfaces which utilize this secondary object, the value of this object is specific to the interface type. During new row creation, the value of this object may be used along with the cienaCesPmInstanceInterfaceId object value to uniquely identify the interface, and such usage may result in the normalization of the values for this object and the cienaCesPmInstanceInterface object, as evident by subsequent get of this object and the cienaCesPmInstanceInterfaceId object.
What is cienaCesPmInstanceInterfaceId2?
This read-create Unsigned32 acts as a secondary identifying index for a PM instance, used specifically when cienaCesPmInstanceInterfaceId alone cannot uniquely identify the monitored interface, per its description, defaulting to zero and unused for interface types that don't need it. This exists because some interface types require a compound key beyond a single numeric ID to disambiguate the exact sub-resource being monitored, similar to how a channelized port needs both a port and channel number. An engineer creating a PM instance on an interface type known to require this secondary index would need to supply the correct sub-identifier value here, rather than leaving it at the default zero used by simpler interface types.
