Basic CBWFQ:Please confirm if this is "input"?

Task:

Implement QoS. Traffic from YourBOGUSBackbone needs to be

limited to 2000Kbit with burst 10K on R3 fa0/0.

R1-----R3(fa0/0)----------YourBOGUSBackbone

My question:
Is the implementation below using "service-policy input" correct?
Someone made a point that CBWFQ only can be applied as 'output". Is that right?

I know that policing can be applied as input or output policy...

R3:

class-map match-all CBWFQ

match any

!

policy-map CBWFQ

class CBWFQ

police cir 2000000 bc 1250

Interface fastethernel 0/0

service-policy intput CBWFQ

Re: Basic CBWFQ:Please confirm if this is "input"?

Hello Marlon,

CBWFQ refers in modular QoS to the use of commands like bandwidth or priority with their variations, a policy map like the  that can only be applied outbound. In your case you have a policer that can be applied inbound with a name of CBWFQ that can be misleading but it is possible.

A policer provides control on the traffic rate for the class.

your policy is not an example of CBWFQ is an example of a service policy that provides traffic rate control

Hope to help

Giuseppe
