Hi,

You need to use the police command instead:

Hi,

Did you check your classification is working correctly ?

How is the trust state of your ingress interface. If they are in untrusted mode, you need to match DSCP 0 instead of default.

Here is an example:

mls qos

!

class-map match-all data1

match access-group 145

class-map match-all data2

match ip dscp 0

!

!

policy-map EGRESS

class data2

police 11000000 512750 exceed-action drop

policy-map INGRESS

class data1

police 11000000 512750 exceed-action drop

!

!

interface FastEthernet0/x

(...)

service-policy input INGRESS

service-policy output EGRESS

!

access-list 145 permit ip any any
