PBR and NBAR - Prioritize bandwidth percentage for a specific application

[Dave4692312]

Greetings,

I am looking for help with a sample configuration that will allow 80% bandwidth utilization for an application, and the rest of available bandwidth for all other traffic.

Thank you

Egress QoS often varies much depending on platform, and sometimes IOS version.  So, what platform and IOS?

Ok, for your egress QoS, something along the lines of . . .

class-map match-all SpecialApplication
match . . . !you can match on ToS tag and/or use an ACL reference

policy-map Sample
class SpecialApplication
bandwidth percent 80
class class-default
bandwidth pecent 20

interface X
service-policy output Sample
