usdMplsIfMinorLowerIfIndex

Module: Unisphere-Data-MPLS-MIB

OID (symbolic): Unisphere-Data-MPLS-MIB::usdMplsIfMinorLowerIfIndex

OID (numeric): 1.3.6.1.4.1.4874.2.2.54.1.3.1.2.1.3

Node type: OBJECT-TYPE

Type: InterfaceIndexOrZero

Access: read-only

Description: The ifIndex of an interface over which this MPLS Minor interface is to be layered. A value of zero indicates no layering. As minor interface can be created without stacking on major interface, as and when it stacks on major interface by signalling protocol, it's value can be read.

What is usdMplsIfMinorLowerIfIndex?

The ifIndex of the MPLS Major interface this Minor interface (tunnel) is layered over; reads as zero if the minor interface hasn't yet been stacked onto a major interface by the signaling protocol, since a minor interface can exist before that stacking happens.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.54.1.3.1.2.1.3
snmpwalk -v2c -c public <target> Unisphere-Data-MPLS-MIB::usdMplsIfMinorLowerIfIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.54.1.3.1.2.1.3.1
