QoS Marking

Hi all,

When trusting DSCP marking where should i put "mls qos trust dscp"? On all edge port, including uplinks? Should i also configure this on the core switch? And lastly how can i check that coming from the LAN to the router the DSCP marking was not changed? Thanks a lot for any feedback.. I have some idea about this but i would like to make sure. Again thanks!

QoS Marking

John

QOS is a big subject.

Basically you need to employ QOS through the whole network.

So yes if you start implementing on the edge you need to carry on through the core too.

Depending on switch models

3750 2960 etc

lets say your router is on interface fas 1/0/1

show mls qos int fas 1/0/1 stat

This will show which DSCP values are being sent out and in from the interface.

Regards,
Alex.
