Hello Divine
You can set up your Policing QoS on the following
access-list 1 permit ip any 1.1.1.1 Subnet 1
access-list 2 permit ip any 2.2.2.2 Subnet 2
class-map Vlan 1
match access-group 1
class-map Vlan 2
match access-group 2
policy-map 10mbps
class valn 1
police 10000000 bc 26000 be 26000 exceed-action [drop]
class vlan 2
police 10000000 bc 26000 be 26000 exceed-action [drop]
Than you can to bind it to the output of the VLAN interface
interface vlan 100

mls qos
