adnAtmInterfaceLowLayerIfIndex
Module: ADN-MIB
OID (symbolic): ADN-MIB::adnAtmInterfaceLowLayerIfIndex
OID (numeric): 1.3.6.1.4.1.637.3.1.4.37.1.2.1.1
Node type: OBJECT-TYPE
Type: InterfaceIndex
Access: read-only
Description: The ifIndex of the logical or physical line supporting this ATM interface. The line is considered to be the lower layer of the ATM interface. Common Name: Lower Layer Interface Index
What is adnAtmInterfaceLowLayerIfIndex?
This interface index points to the underlying physical or logical line that carries an ATM interface (one layer below in the stack). When diagnosing ATM performance, an engineer checks this to move down the stack — if ATM errors spike, they check the physical line's health. For example, ifIndex 23 might point to the SONET line that physically carries the ATM traffic.
