hi,

i have some question about qos in layer2.

we have a router on one side which does qos with the dscp value which we are settin in the router based on acl?s.

the router is connected over a ethernet to a switch (no trunk).

how can i achive that the switch does qos based on the dscp values which the router is setting.

I have this problem too.

hi, thank you.

just one (two) questions regarding this:

if the router sets the dscp value in the ip header, who sets the 3 bits cos value in layer two even this connection is no 802.1q

connection - its a user port in the switch.

- does the switch automaticly sets cos from the layer3 dscp it receives from the router ?

thanks for answer
