Despite its name, this object's own description defines it as a counter of inbound packets discarded (with no error detected) on this virtual WAN link, e.g. to free up buffer space, rather than a throughput rate; it can reset at re-initialization or per maxWanCounterDiscontinuityTime. An admin monitoring this counter for a specific virtual WAN link watches for unexpected discards that could indicate buffer exhaustion under load, keeping in mind the discontinuity behavior when interpreting a sudden drop in the count.
