Percent in a Policy map is a derivative of Mincir but only IF IF there
is a traffic shaper present on the interface.
If there is no traffic shaper present - then Percent is a derivative
of the "bandwidth" command.

Ryan.
I got really disappointed for lack of what i call "friendly"
approach about this part of QOS so I left it alone for a while and
today i came back to give it another shot and then WOOOW Ryan you
are a life saver . nice explanation pal.
That was exactly where i got lost in QOS and now I am all clear.
May i ask you one question about QOS marking .
There are different approached to do the marking specially about the
CS3 marking since new SRND recommends to remark the SIG with CS3 .
I see different approaches to achieve this using class Maps
1. Match Protocols in class-map and remark with policy-map
2. have access-lists to match the packets , then match with class-
map following with remarking by policy-map
3. using dial-peer commands where call is hitting the WAN directly
( for example from CME to GK to CCM ) like "ip qos dscp cs3 signaling"
can one of these methods do the whole job of matching so we don't
put time on configuring for example each and every dial-peer with
CS3 .
I personally think the access-lists are the one who can take care of
this matter.
having an access list and match "any with destination port SIP or
SCCP or MGCP ..."and assign it to class-map and remark it with
policy-map
Please advice .
Best of regards.

256 divided by total bandwidth maybe? I don't know. Can't assign

Subject: [OSL | CCIE_Voice] QOS LLQ
Hi everybody . hope you all having a good day .
got a question about QOS LLQ .
as far as i understand to reserve amount of bandwidth for media and
control where media=256kbps and SIG=8 kbps
Class RTP
priority 256-------> 256 Kbps of which bandwidth, Interface or CIR
or MINCIR
Class SIG
Bandwidth 8 -------> same as above question
also what if we have to allocate percentage of bandwidth in the
above mentioned scenario what would be the correct percentage to use
with
eg. allocate VOICE=256kbps and SIG=8kbps .
Class RTP
priority percent-------> what to calculate for this
Class SIG
priority Precent------->same as above question
basically i,m lost in calculation of these parameters.
