mplsLdpEntityAtmIfIndexOrZero
Module: MPLS-LDP-ATM-STD-MIB
OID (symbolic): MPLS-LDP-ATM-STD-MIB::mplsLdpEntityAtmIfIndexOrZero
OID (numeric): 1.3.6.1.2.1.10.166.5.1.1.1.1.1
Node type: OBJECT-TYPE
Type: InterfaceIndexOrZero
Access: read-create
Description: This value represents either the InterfaceIndex or 0 (zero). The value of zero means that the InterfaceIndex is not known.
However, if the InterfaceIndex is known, then it must be represented by this value.
If an InterfaceIndex becomes known, then the network management entity (e.g., SNMP agent) responsible for this object MUST change the value from 0 (zero) to the value of the InterfaceIndex. If an ATM Label is being used in forwarding data, then the value of this object MUST be the InterfaceIndex.
What is mplsLdpEntityAtmIfIndexOrZero?
This object holds either the ifIndex of the ATM interface this LDP entity runs over, or the value 0 if that interface index is not yet known. It matters operationally because once an ATM label is actually being used to forward data, the agent is required to update this value from 0 to the real InterfaceIndex, so it can serve as a live indicator of whether the LDP-ATM binding has been resolved. For example, a value of 0 on a newly configured LDP entity tells an admin the ATM interface mapping hasn't been established yet, while a nonzero value like 3 confirms it is now tied to ifIndex 3.
