Module: MPLS-LSR-STD-MIB

OID (symbolic): MPLS-LSR-STD-MIB::mplsInterfacePerfInLabelLookupFailures

OID (numeric): 1.3.6.1.2.1.10.166.2.1.2.1.2

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

What is mplsInterfacePerfInLabelLookupFailures?

Counts labeled packets received on this interface that were dropped because no matching cross-connect entry existed for their label. A rising count points to a misconfigured LSP or a label that expired on this router but is still being sent by an upstream neighbor.
