I want to setup QOS in our LAN network where there isn't any voice traffic. But we got important traffic that needs priority. We have 2960 and 6509-Eseries running HSRP and OSPF.

Hi thanks for the Help, but i got those files.

I tried configuring qos on the 2960, tried classification using  mac-access list and normal access-list and then tried to mark the packets using dscp. Then i tried to monitor the packets but i cant find any markings on the packets . So could you give me a sample config  for a 2960.

Two questions, is any routing being performed in the topology?

Second, if not, how are you marking your packets as they traverse from your source?

You will either need to figure out a way to mark every packet leaving your devices (QoS Packet Scheduling?) or roll them through a routed interface so that you can identify the packet (switches only care about the frame unless layer three enable and configured) and mark/schedule as necessary.

Yes we got routing enabled on layer3 interfaces (OSPF) in 6509E-series, but i am marking the packets on 2960 with COS vlaues. but after re reading the PDF u send i tried and it did work good.

Thanks for the help, in anycase can you help me out with some sample config of qos for 6509 and 2960 to just verify about the queue settings.
