Hi, Thanks your advice again. I am just trying the method to provide Per-VC QoS based on IP header information (in our case is IP precedence). From cisco documentation, I found WRED, Set-CLP, WFQ/CBWFQ/LLQ will proivde IP-to-ATM CoS.
>From your comment, you recommend use queueing method to do that. Can you give me more hints about that? Something like the following class-map voice match ip precedence 5 class-map data match ip precedence 0 .... policy-map policy1 class voice bandwidth/priority percent 60 class data bandwidth percent 20 .... interface atm1/0.100 point-to-point pvc 1/100 service-policy output policy1 I'm confused the use of bandwidth and priority command. They are guaranteed bandwidht or reserved bandwidth? In the above example, does it mean the data can only have up to 20% of bandwidth even NO voice traffic persent (no link congestion)?
