From what I gather, the "bandwidth percent" command gives you the minimum
bandwidth available, and the police command limits the maximum. So in the
example the class will always have a minimum of 231600 bits available and
will have a maximum of 300000 bits available. This is what is stated in
DQOS by knowledgenet. Does anyone agree or disagree, or have any links on
cisco.com?
thanks

police normally means rate-limiting in the ingress direction whereas
bandwidth specifies the amount of BW reserved in the egress direction.
Starting from 12.2, the bandwidth percent refers to the percentage
calculated from the bandwidth of the port, say configured by the bandwidth
command or simply LINE RATE.
Please clarify me if I made any wrong assumptions.

Subject: CB policing with bandwidth command
I am looking over some sample configs and one of them is using class based
policing and the bandwidth command under the class. Here is the config:
policy-map CCIE
class color
bandwidth percent 15 <-------------
police 300000 1500 3000 conform-action ....................
int ser0/0
ip x.x.x...
service-policy out CCIE
clockrate 1544000
What exactly does the bandwidth command do when used in conjuction with the
police command? I thought maybe 15% of the int bw would be 300000, but 15%
of 1544000 is 231600.
thanks in advance.
