QoS Configuration - help needed

[fabiogarcia]

Hello Everyone!

I have a 2Mbps link where I need tom confgure a QoS... I already have a QoS configured over there but my Netflow tool shows me a different scenario preety much different from my QoS CLI Config

This is my config below

policy-map qos_new

class voip

  priority percent 30

class signaling

  bandwidth percent 5

class web

  bandwidth percent 30

class critical_data

  bandwidth percent 30

class SHAPE_FILE_SERVER

   police 512000 conform-action transmit  exceed-action drop

class class-default

  fair-queue

The identification is working fine, but I think there are some strange behavior during the day, where specially the class SHAPE is not being shaped as I expected... etc etc

- Do you guys have any suggestion to change that config ?

- Does anyone have some documention with best practicies regarding this config, maybe with some xamples.. etcetc

- Shall I change the class-default line ?

thanks thanks thanks!

What direction do you have this applied in? Personally, I'd change the class SHAPE_FILE_SERVER to shape the traffic instead of policing it. You can only shape outbound on an interface though which is why I asked. Otherwise, if you're applying inbound, the rest of the policy wouldn't make sense so I'm assuming you're applying this outbound

That being said, I'd change your police line to "shape average 512000" and see if you get better results. Your class default looks fine. In fact, there are some people who guarantee bandwidth for the class default so that traffic doesn't starve.

HTH,
John
