mls qos trust xxxx


I did some testing with an Autonomous AP and mls qos on a switch.

When you’re using a native vlan and you want to trust the qos, you’ll have to trust DSCP.
If you’re using a tagged vlan, trust COS….

I wasn’t aware of this….

with
mls qos map cos-dscp you can change the cos-dscp mappings.

With
mls qos ip dscp-mutation NAME
you can change the dscp-dscp mapping… (Very nice to simulate a switch which is a SP with wrong qos mapping)
