Important Considerations
The transmit statistics help you track bandwidth utilization and packet
loss by physical port and queue (reserved, high, best, and low).
The RSVP and network control packets go out on the reserved queue.
When you mark any packet (conforming or excess) as loss
eligible, the packet is dropped if the transmit queue for which it is
destined is over its threshold. A packet that is marked loss-eligible falls
into one of the two highLoss statistic categories:
If the transmit queue is not over its threshold, the packet is sent
and counted as a highLossSent packet.
If the transmit queue is over its threshold, it is dropped and
counted as a highLossDropped packet.
If you do not mark a packet as loss-eligible, it falls into one of the
three lowLoss statistics.
If the queue is not over the threshold, it is counted as a
lowLossSent.
If the queue is over its threshold, it is counted as
lowLossDelayed.
If the queue is full, it is counted as lowLossDropped.
Loss-eligible packets are conforming packets that are discarded
instead of queued when transmit queues back up beyond a threshold.
You can specify whether conforming packets (as well as
nonconforming excess packets) are loss-eligible when you define a
control. Marking packets loss-eligible is useful to enable intelligent
discard of traffic in a congestion situation. When the system is
congested, you can decide which traffic can be discarded and mark
that traffic as loss eligible.
