Hi group,
Am I right to understand that:
o 3550 by default with 'mls qos' turned off will not trust any DSCP/COS values
o After turning on 'mls qos' global command, unless explitcly configured to
trust dscp/cos values per interface, it still won't trust.
Is this correct or am I way off?
I'm trying to police a port on a 3550 in both in/out direction. Since IP ACL
only does ingress, and DSCP does both, I'll use DSCP code 0 to match in/out.
But so much for DSCP if the user on the policed port changes DSCP values and
switch trusts them :)
Thanks for the tip!
-J
