Voice QoS

Nabs

 

Hi all,

I have a question about policy-map on one exam question:

This is the exam question  :

Configure a router with:

- a strict priority queue with 128kbps guarantee for the voice class is reserved

- a minimum bandwith guarantee of 30 kbps is configured for the class interactive

-  a minumum bandwith guarantee of 16kbps for bulk and limit the
class to an average rate of 24 kbps by buffering excess traffic (use
the IOS default Bc and Be).

- and the default class is configured for WFQ with no bandwith guarantee.

 

I have made this:

policy-map llq-policy

class voice

priority 168

class interactive

bandwith 30

class bulk

bandwith 16

shape average 24000

class default

fair-queue

 

but the exam answer this:

policy-map llq-policy

class voice

priority 168

class interactive

priority 30

class bulk

priority 16

class default

fair-queue

 

I am not sure about what I have done. So what do you
think about my answer and the exam answer ?

 

Thant you in advance for your help
