Hello,

Ciscoworks is often reporting the event HighQueueDropRate on some of
my wireless routers (837, 877w, ...)
for example, today : InputPacketQueueDropPct 1.6998109 %
but it could be OutputPacketQueueDropPct.
basically, the value is set to 1% (default value)

I would like to know if somebody have an idea of why I've got this
event (only on wireless interfaces), and how to decrease the number of
droped packet (please not how to set the value at 2% on
Ciscoworks :D ).

thanks

I suppose you could police your data flows so that your traffic throttling
doesn't show up as interface drops. No particular practical reason to do
that, that I can think of.

What is your goal/concern here?

I would like to be sure that quality of service is always good enough.
I just wonder if it's a real issue. Users never report any problems,
but if Cisco set this rate to 1%, that probably mean it's not very
good to be often over it.
If you tell me more than 1% of dropped packet is normal for a wireless
interface, it will be fine.
