mplsInterfaceInDiscards
Module: MPLS-LSR-MIB
OID (symbolic): MPLS-LSR-MIB::mplsInterfaceInDiscards
OID (numeric): 1.3.6.1.3.96.1.2.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of inbound 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 mplsInterfaceInDiscards?
This Counter32 counts inbound 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 monitors this counter to catch MPLS-layer congestion drops that wouldn't show up in lower-layer interface error counters. A steadily increasing value here, especially alongside a shrinking mplsInterfaceAvailableBuffer, points to buffer-related congestion on that interface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.3.96.1.2.1.3 snmpwalk -v2c -c public <target> MPLS-LSR-MIB::mplsInterfaceInDiscards
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.3.96.1.2.1.3.1 snmpget -v2c -c public <target> MPLS-LSR-MIB::mplsInterfaceInDiscards.1
