mplsInterfaceFailedLabelLookup
Module: MPLS-LSR-MIB
OID (symbolic): MPLS-LSR-MIB::mplsInterfaceFailedLabelLookup
OID (numeric): 1.3.6.1.3.96.1.2.1.4
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This value indicates the number of labeled packets that have been received on this interface and were discarded because there were no matching entries found for them in mplsInSegmentTable.
What is mplsInterfaceFailedLabelLookup?
This OID counts packets received on an MPLS interface that lack a matching forwarding entry in the label table. MPLS uses numerical labels for faster routing than address lookups, and missing entries cause packet drop. An engineer would monitor this to detect routing misconfiguration or attacks sending packets with invalid labels.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.3.96.1.2.1.4 snmpwalk -v2c -c public <target> MPLS-LSR-MIB::mplsInterfaceFailedLabelLookup
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.3.96.1.2.1.4.1 snmpget -v2c -c public <target> MPLS-LSR-MIB::mplsInterfaceFailedLabelLookup.1
