QoS Congestion

[Youn88]

Hello,

I have two separate streams at the input of my L3 switch. The first stream is marked EF and the second is marked AF11.
I would like to check that the EF traffic is prioritized in case of congestion.

I started by configuring two separates class-map that match DSCP 46 for EF and DSCP 10 for AF11.

I am stuck in the configuration of the policy-map, how can I do that ?

Thank you in advance

Can you post your config for the class-maps?  Once you configure you class-maps, you can configure your policy-maps like this:

policy-map xxx-OUT

  class-map ef-data

     priority percent 10

 class xxx

     bandwidth remaining percent 50

 class xxx

    bandwidth remaining percent 45

 class class-default

    bandwidth remaining percent 5

There are tons of different variations you can do with QoS depending on what your goals are.  My example above is a very basic example.

What model switch and what IOS version and what IOS feature set?

Please further define what you mean by wanting "to check that the EF traffic is prioritized in case of congestion."
