mplsLdpEntityAtmIfIndexOrZero
Module: MPLS-LDP-ATM-MIB
OID (symbolic): MPLS-LDP-ATM-MIB::mplsLdpEntityAtmIfIndexOrZero
OID (numeric): 1.3.6.1.2.1.116.1.1.1.1.1
Node type: OBJECT-TYPE
Type: InterfaceIndexOrZero
Access: read-create
Description: This value represents either the InterfaceIndex of the 'ifLayer' where the ATM Labels 'owned' by this entry were created, or 0 (zero). The value of zero means that the InterfaceIndex is not known. For example, if the InterfaceIndex is created subsequent to the ATM Label's creation, then it would not be 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 read-create value is the InterfaceIndex of the ATM interface where the ATM labels owned by this LDP entity entry were created, or 0 if that InterfaceIndex is not yet known. An admin or management system relies on this to tie an LDP-over-ATM entity to its actual physical or logical ATM interface, which the agent must update from 0 once the InterfaceIndex becomes known. A value of 0 means the ATM interface index wasn't known at label creation time, but once the LSR uses this label for forwarding, this object must report the real ifIndex, e.g. 14.
