mplsInterfaceOutDiscards
Module: MPLS-LSR-MIB
OID (symbolic): MPLS-LSR-MIB::mplsInterfaceOutDiscards
OID (numeric): 1.3.6.1.3.96.1.2.1.7
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of outbound labeled packets, which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a labeled packet could be to free up buffer space.
What is mplsInterfaceOutDiscards?
This Counter32 counts outbound labeled packets that were deliberately discarded on this interface even though no transmission errors were detected, for example to free up buffer space under congestion. An admin watches this counter for signs of egress-side MPLS congestion distinct from the inbound discards tracked separately. A rising value here on an LSR's core-facing egress interface suggests that interface's outbound queue is regularly hitting capacity and dropping labeled traffic.
