QOS on WAN Links

Dear QOS Experts,

I have to set up a qos for my wan circuits. We use 200M links. My requirement as i need to dedicate 1MB committed bandwidth and 2MB as cap for specific SVI Vlan(public IP) which is configured in our core switch. I don't want to prioritize any traffic. I found couple of solutions where i see all with prioritizing, shaping & classification. Can anyone help me to meet my simple requirement. 

Thanks,

Satish.

For what platform and IOS?

Hi Joseph,

Thanks for your response. 

Cisco 1941 Router 

IOS: c1900-universalk9-mz.SPA.154-3.M5.bin.

I see below config in router already which is never applied to any of the interface. 

But my requirement seems to be different than the config existing in router. I only need to know how to apply 1MB CIR at 2MB Bc. I don't care about any other criteria. 

Existing qos config in device:

class-map match-all OUT
match access-group 11
class-map match-all ABC-OUT
match access-group 10
class-map match-all IN
match access-group 222
class-map match-all ABC-IN
match access-group 111
!
policy-map traffic-LAN
class ABC-IN
shape average 2000000
class IN
shape average 10000000
class class-default
fair-queue
policy-map traffic-WAN
class ABC-OUT
shape average 2000000
class OUT
shape average 10000000
class class-default
fair-queue
!
!

access-list 111 permit ip host 1.1.1.1 any
access-list 10 permit ip any host 1.1.1.1
access-list 11 permit ip host 1.1.1.2 any
access-list 222 permit ip any host 11.1.1.2

** But policy not applied any where. 

I'm least bothered about this QOS in device. I need to know what i should configure to achieve my criteria. 

This is internet circuit(fiber). Not ATM or Framerelay circuit. 

thanks. 

I was successful to fulfill my requirement myself and no more assistance required on this thread.  

Thanks,

Satish. 

Great!  Thanks for letting us know.
