[c-nsp] silly qos question

[Jeremy Stretch]

With the 656 Kbps limit for the Data-DSCP class, your reserved 
bandwidths total 1152 Kbps, or 75% of a 1.536 Mbps interface. Remember 
that by default IOS will only reserve up to 75% of an interface's 
bandwidth. You should be able to change this with the 
'max-reserved-bandwidth <percent>' command applied to the interface.
