Angelo,
The queueing methods always work with outbound traffic. Typically used
with slower interfaces though. Queueing is always working, but like you
said, if the traffic load isn't high, it's really not giving you any
benefit. I don't think you'll see anything useful with Sniffer. The router
can send the traffic pretty much as soon as it arrives at the outgoing FE
interface. The queue never fills beyond a couple packets, so no
prioritization ever takes effect. I think you've just got to trust the 'sh
queuexxx' commands. Or else set up back-to-back aux ports, and create a
very slow link. Then you'll see the difference, especially if you run an
FTP session, and prioritize telnet. That's where it shines.
