What is ibIfPortStatSwLifetimeDiscards?
This counter, applicable only to InfiniBand switches, tracks outbound packets discarded because they exceeded the switch's configured lifetime limit while queued for transmission. A rising count indicates packets are spending too long in switch queues before being forwarded, typically a sign of congestion within the fabric. An admin seeing this counter climb on a switch port would investigate downstream congestion rather than the port's own physical link quality.
