QoS for App-V

[florent.appointaire]

Hello,

I'm currently configuring new 3750X switches.

I must implement QoS on the stack. The QoS must be the following:

• VOIP Class (50%)
• App-V Class (40%)
• Movie Class (10%)

How I can do this (in particular for AppV)? I do the following for the moment:

class-map match-any VOIP
match protocol voice
match  dscp ef
match protocol sip
match protocol skype
match protocol rtp audio
match protocol rtp video
exit
class-map AppV
exit
class-map Movie
match protocol rtp video
exit

policy-map BandwidthTraffic
class VOIP
priority percent 50
set dscp ef
class AppV
bandwidth remaining percent 40
class Movie
bandwidth remaining percent 10

interface Gig1/0/3
ip nbar protocol-discovery
service-policy input BandwidthTraffic

Anyone can says me if it's correct or not? And why?

Thank you for your help.

Florent

It appears you've some router QoS.  3750X QoS is quite different for egress as you're limited to working with four egress queues.  I don't recall 3750X supporting NBAR.

Suggest you read the configuration guide's chapter on QoS, for you 3750X IOS version, and then post questions as necessary.  (My concern is, 3750X QoS is so different, it wouldn't be helpful to suggest a QoS configuration until you had a basic understanding of the 3750 QoS architecture and features.)
