1. Why not make max-reserved bandwidth 100%, also if you used "bandwidth
percent" under your policy map would you need to set the bandwidth.
2. Your setting CIR, which on a Cisco box is port access-rate, mincir is
what I would have thought you should use, this is what we would "normally"
call CIR. I think your getting 50% because by default mincir is 1/2 of cir.
These terms and contradictions have popped up many times recently so I won't
explain any further....I'm sure they'll come up many times more ;-)
