QOS: GOLD + Citrix...

Hi,

We have a need to provide "GOLD" priority to a clients ethernet connections between our POPS(I have attached config that will hopefully achieve this over 2 PE's) - The client is also requesting that Citrix traffic be given the highest priority also - Just wondering the best way to achieve this?

Client LAN subnets (Example):

Site A - 10.10.1.0/24

Site B - 10.10.2.0/24

I would assume that a similar QOS be implemented on the CE's to ensure end-to-end GOLD priority, and also give Citrix the highest priority.

Neglected to attach config in original!

Hi John

There is 2 ways to solve your request:

1. Make the customer mark his traffic with the correct QoS marking and then trust these on ingress. (Usually not a good solution for SP's)

2. Mark traffic on ingress using Class based marking.

You can use NBAR to match citrix applictions and do your tagging on ingress interfaces, that is interfaces towards customers.

example:

class-map citrix-app

match protocol citrix app

policy-map setcitrixhigh

class citrix-app

set dscp af31

set precedence 3

set cos 3

class class-default

set dscp be

set precedence 0

set cos 0

interface fastethernet0/0.100

service-policy input setcitrixhigh

This would sure high QoS for Citrix applications. Just make sure you choose the right Citrix applications.

Re: QOS: GOLD + Citrix...

Thanks for the assistance - When I attempt to apply the policy map to subint, I am getting:

(config-subif)#service-policy input mfsw-setcitrixhigh

Process 'set' action associated with class-map citrix-app failed:

Set cos not supported in input policy

I have the following:

class-map match-all citrix-app

match protocol citrix

policy-map mfsw-setcitrixhigh

class citrix-app

set precedence 3

set cos 3

class class-default

set precedence 0

set cos 0
