[OSL | CCIE_Voice] WAN QoS Calculations
QoS Guru's, In the real lab I know I have to do some calculations utilizing 95% of the bandwidth...so if there is a link between SA and SB of 384k and SA and SC of 768k is the 95% from these numbers or what the actual interface can do? Also what is a simple straight to the point read on this, I really don't want to review an srnd?

Re: [OSL | CCIE_Voice] WAN QoS Calculations
From those numbers, those are the CIR values of the PVC, so you have to use those values. They physical circuit would be a T1, which is academic as the carrier can discard above the committed rate.

Re: [OSL | CCIE_Voice] WAN QoS Calculations
I believe that a 768kbps link falls within the recommendation to leverage a fragmentation mechanism. So, I believe that the map-classes are accurate. Hugo, I know you said you don't want to review a SRND but I definitely recommend you take the time to a look at the WAN Edge Link-Specific QoS Design in the QoS SRND. It is an informative section and not as much of a yawn fest as you may think. Also, if you are ever asked to do class-based traffic shaping, you will be comfortable where to find some good examples. Remember that the QoS SRND is made available to you on the candidate machine. -Bill -- William Bell blog: http://ucguerrilla.com twitter: @ucguerrilla On Apr 9, 2013, at 6:19 PM, Leslie Meade wrote: Hmmm I cannot remember but I am 95% sure J that the fragmentation is not for links over 768… Hence the map-class for the link to Site C is incorrect… remove the frame-relay fragment 960 From: Barrera, Hugo [mailto:hugo.barr...@nexusis.com] Sent: Tuesday, April 09, 2013 3:17 PM To: Abel ...; Leslie Meade Cc: ccie_voice@onlinestudylist.com Subject: RE: [OSL | CCIE_Voice] WAN QoS Calculations So my first set of commands below this is NOT using 95% of the BW and the second set of commands, in blue, are using 95% correct?

Re: [OSL | CCIE_Voice] WAN QoS Calculations
First I used the SRND for LAN QoS and I believe that to be the best way, but I'm sure there are many other flavors. I found using the SRND for LAN QoS to be quick and easy, page 107. It's very efficient way to do it and eliminates mistakes. For WAN QoS I used auto qos voip trust or auto qos voip depending on the question wording. In addition I did QoS first and I know some people disagree with that, but it worked for me speed wise using the device based approach. I did not use the SRND for WAN QoS, but agree is a good reference to have since it's on the desktop of the lab. I used the 95% rule as well as removing the rmon commands. I passed. I agree with most of the comments especially read the question very carefully.
