When the BSGX4e is polled by a SNMP network management workstation, the QoS
counters can be incremented. You may observe downgraded packets because the
Quality Group Management uses a CAR policer (if the offered load is higher than 64
Kbps, it is downgraded in best effort). You may observe dropped packets if the
offered load exceeds the burst rate (1 000 000 bps), but this is unlikely.

When other traffic types run, they are managed in best effort mode. It is likely to
have packets dropped, showing that low priority packets have been discarded by the
QoS mechanism because the offered load has been greater than the QoS link rate (1
684 450 bps).
