Two questions here:
I have used the following basic configuration to do rate limiting on a vlan interface on a 6509:
access-list 100 permit ip any any
class-map match-all ratelimit
match access-group 100
policy-map ratelimit-10Mb
class ratelimit
police 10000000 428750 conform-action transmit exceed-action drop
interface Vlan1
service-policy input ratelimit-10Mb
service-policy output ratelimit-10Mb
This works in lab just fine- when applied in production the output service policy works, but the input policy still allows 100Mb of traffic. Im not sure why this is occuring- the only difference in configuration is that the data in production goes thru 2 different switches before it hits the route point.
Secondly, Im having trouble with adding QoS for voice to the mix on the same policy map. I dont want to have to completely set aside a certain amount of bandwidth simply for voice and lessen their data performance, but it doesnt seem to work the same way as with most routers:
class-map match-any QoS-voice
match ip dscp ef
match ip dscp cs6
policy-map QoS-voice
class QoS-voice
police 2000000 234375 conform-action transmit exceed-action drop
interface Vlan1
service-policy output QoS-voice
How do I combine the two correctly to give me a vlan port rate limited at 10Mb up and down, but still setting aside (dynamically) 2Mb for voice?
Thanks

Hi
1) Could you provide the simple diagram? also the config portion of VLAN 1 associated ports if any. Where you are seeing 100MB ? is it by using "show interface" ? can I have the "show policy-map interface vlan 1?
2) It will helpful if you elabrate you findings on what didn't work. Also, it is advisable to use the strict priority Queuing for voice traffic. You can refer the design technotes for C6500 here http://www.cisco.com/en/US/products/hw/switches/ps708/tsd_products_support_design_technotes_list.html
