Policy-Map / QoS

I have an issue at a remote site that when I run backups (on 1 server) that it brings the WAN to a grinding halt. I thought I would use QoS/Policy map to guarantee bandwidth for Citrix and printing but does not seem to be working. It appears that it's not interpreting the protocols citrix and printer. Just wanting a second pair eyes to see if maybe I'm missing something .

class-map match-all citrix

match protocol citrix

match protocol printer

Re: Policy-Map / QoS

Is the NBAR making it possible to classify the protocols like this?

I didn't see it defined any where else:

match protocol citrix

match protocol printer

"Is the NBAR making it possible to classify the protocols like this"

Yes it is. The "match protocol" within a class-map is what triggers use of NBAR for classifying traffic.

Re: Policy-Map / QoS

Thanks Jon,

Are there guideline documents on how to use NBAR and QoS like this?

We have NBAR configured on our router interfaces, but it is not in use in QoS policies like this.

We have MARS monitoring the network, does it use NBAR?
