By default QoS is disabled. But what is its exact behaviour?
I've read that DSCP is trusted, COS untrusted when QoS is disabled.
What will be the result for the queuing on the egress queue?
Will packets scheduled based on the Cos value? this means:
COS to DSCP mapping=> DSCP 0
DSCP to Tx queue=> Tx 1 for all traffic and DSCP value set to 0
or the DSCP value keeps maintained and the default DSCP to Tx queue mapping is used?
I've no hardware to test and I don't find the exact information online
