What is cpwVcMplsInboundTunnelInstance?
This is the inbound tunnel instance value paired with cpwVcMplsInboundTunnelIndex, distinguishing between parallel instances (like primary vs. backup LSPs) of the inbound TE tunnel serving this pseudowire. Watching this value change after a network event, while the pseudowire itself stays up, is direct evidence of a TE protection switchover having occurred on the receive side. Engineers correlating a brief packet-loss blip with an unexplained change in this instance value can attribute the blip to an inbound TE reroute rather than a pseudowire fault.
