Simple DSCP marking

[davidmesquita]

Hello

I am trying to set up a simple configuration on a Cisco 4928-10G switch running

cat4500-entservicesk9-mz.122-37.SG.bin

All I want to do is to mark all trafic on vlan 3 let's say for this example with dscp af31.

All outgoing trafic to be marked with DSCP AF31.

In pratice If I have 2 laptops connected to access ports on vlan 3.

When one laptop pings the other I want to see on the receiving end when I run wireshark the traffic to come marked with DSCP AF31.

Any suggestions of sample configurations guys ?

Thank you in advance.

Regards

Hi ,

You must set on every port the default DSCP value. For AFxy the dscp value is 8*x + 2*y.
