l3 ip-prec and l2 cos

[rabeder]

hi,

i have a router which receives traffic on an ethernet and the router marks this traffic with the ip precedence value from 0 to 5.

the router is then on a second ethernet interface to a third-party switch connected .

now i want that the router also sets the layer2 cos value, so that the switch can do queueing based on the layer2 cos value.

how to do this ?

thanks for answer

You need to create Class-map and then set CoS value for that class. Refer to the QoS configuration guide for the commands,
