Group,

I am inquiring about queuing option's within the 6500 platform for routed
interfaces.

I am looking at a scenario where I have 2 6500's with Ten Gig modules, and
the default queuing is FIFO, but having a hard time where to go with
prioritizing Voice and Video etc etc. Here is my interface and my queuing
info.

Any idea's? or a good document to help me understand my options here?

Thanks in advance!
