Re: CQ band reservation

You need to configure "queue-list 1 default x" so other traffic goes to a specific queue. The default byte-count will be 1500 for the default queue.

Concerned to if it can use up to 100% of the bandwidth thse are my though:
(I hope somebody else comment it)

1-if you are applying it to a physical inteface, maximum-reservation will let you use up to 75% of the interface bandwidth

2-if you are applying it to a DLCI, maximum-reservation does not apply, so you can use up to 100% of the mincir

3-if you are using ATM, I really hope somebody else help us here. I posted a question yesterday about this because I found two opposite statements from Cisco. They are:

=======================
"The max-reserved bandwidth command is intended for use on main interfaces
only; it has no effect on virtual circuits (VCs) or ATM permanent virtual
circuits (PVCs)."

from 'Low Latency Queueing with Priority Percentage Support', 12.2(2)T New
Feature
(http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t2/ftllqpct.htm)

"You now can increase the maximum reservable bandwidth value on ATM PVCs
using the max-reserved-bandwidth command"
