Re: 3750 Outbound Queues

Hi Tony,

Yes of course I could map packets into Q2T2 based on markings. The
confusing thing is that there is no configuration that maps packets of any
kind into that queue / threshold and there is also nothing in the
configuration or output-q output that shows anything for Q2T2, yet there
are packets seemingly being put into that queue on output. That makes no
sense.
