WAN qos question

Here is the statement from AVVID QOS SRND p118. Does this mean if I have two policy on the gw, and priority queue in the two policy has to use same method, either absolute or percentage? Thanks

If the percent keyword is used for one LLQ provisioning, then it must be used for all other LLQ

provisioning (as in the case of voice and video). Likewise, if an LLQ is provisioned in terms of absolute

kbps, then any additional LLQs must also be provisioned in absolute kbps.

Re: WAN qos question

Inside a single policy map, you must use either percentage based or explicitly stated bandwidth with the priority command. You cannot use both within the same policy map.

Hope this helps. If so, please rate the post.

Exactly as Brandon said, each class within a service-policy need to have consitent bandwidth units, for example assume the following example:

class-map match-any VOICE

match ip dscp ef

class-map match-any CALL-SETUP

match ip dscp af31

match ip dscp cs3 !

!

policy-map VoIP-SITE

class VOICE

priority percent 33

class CALL-SETUP

bandwidth percent 4

class class-default

fair-queue

you could not do the following:

policy-map VoIP-SITE

class VOICE

priority percent 33

class CALL-SETUP

bandwidth 4

class class-default

fair-queue
