MQC Question

$

Hello all,

I need some clarification with respect to Modular QoS CLI commands.

Take for instance, I have the following requirements

1. Class VOICE, match with dscp AF42, to get 40% of available bandwidth (with priority)

2. Class VIDEO, match with dscp AF22, to get 30% of available bandwidth

3. Class OTHERS, match with dscp AF11, to use remaining bandwidth without any guaranteed bandwidth.

Please look at the following commands:

 

class-map match-all OTHERS

 match  dscp af11

class-map match-all VIDEO

 match  dscp af22

class-map match-all VOICE

 match  dscp af42

!

policy-map ALL_TRAFFIC

 class VOICE

  priority percent 40

 class VIDEO

  bandwidth 30

 class OTHERS

 

My question is with the policy that will be applied to the class OTHERS. 

1. When nothing is configured under the class OTHERS, will it have the same effect as class CLASS-DEFAULT with FIFO queueing?

Or do I need to calculate the remaining bandwidth and the apply it to the class?

2. What effect does this have on the CLASS_DEFAULT class? Will the remaining bandwidth be shared between class OTHERS and CLASS_DEFAULT?
3. Is it compulsory to define/configure class CLASS-DEFAULT under all policy-maps?
Im kind of confused. Can someone please help me out.
Thank you.
