Hi : Below is a sample config on rate limit

For your example this could be the configuration

!

! Your access-list defining your internal ! traffic

access-list 101 permit ip x.x.x.x y.y.y.y any

access-list 102 permit ip a.a.a.a b.b.b.b any

.

.

.

access-list 110 permit ip c.c.c.c d.d.d.d any

!class maps matching your access-list

!

class-map 1cust

match address 101

!

class-map 2cust

match address 102

!

.

.

.

class-map 10cust

match address 110

!

policy-map shape-cbwfq

class 1cust

!gurantee of 1mbps shaping it to 5Mbps if !bandwidth available

bandwidth 1000

shape peak 5000000

class 2cust

bandwidth 1000

shape peak 5000000

.

.

.

class 10cust

bandwidth 1000

shape peak 5000000

!

interface fastethernet0/0

desc outside interface connected to internet

service out shape-cbwfq

The above config works for rate limiting, the question i have , within the customer1 (1cust)group, can we shape the traffic by IP subnets etc

thank you

Hi,

if you want to apply treatment per subnet per customer and not per customer anymore, you need a class-map per subnet which match a dedicated ACL which match this subnet.

Hello Krishnan,

you need to used nested policy maps hierarchical policies to achieve this.

For example see

http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a0080114326.shtml#applyingaservicepolicy

http://www.cisco.com/en/US/docs/ios/qos/configuration/guide/qos_mqc_ps6350_TSD_Products_Configuration_Guide_Chapter.html#wp1060235

Recently a three level qos hierarchy has been introduced.

Hope to help

Giuseppe
