Don't forget to use "max-reserved-bandwidth 100" on the interface with the policy. If you don't you are limited to having 75% of the BW of the interface "reservable" since IOS "keeps" 25% for overhead. If you know what your traffic is, use the above so you can control 100%.

Note: in our QoS policies we always have a class for telnet/ssh/ftp/syslog/ntp/etc. so we can reach the device even when it's busy...
