Site2site VPN QoS question

Hi

We have site2site VPN with ASA 8.03 and I configured the QoS on ASA outside interface. But there is no traffic mapping the QoS, here is my QoS setting and show service-policy output. In the output, there is no traffic mapping the class-map ERP. Anyone knows if the QoS can work with site2site IPSec VPN tunnel or any ideas about this issue?

Thanks, Leo

What is your IP subnet on the inside interface?

Re: Site2site VPN QoS question

Thanks for the reply, but when I changed the QoS configuration, I can see there are the traffic can hit the QoS policy. Following the my old and new configuration, anyone knows what's the difference between them? My connection is 3M BDSL circuit, my goal is to priority the ERP traffic, so which configuration is better for my situation?

Thanks. Leo

Re: Site2site VPN QoS question

You are policing to a certain amount - but you are not defining a priority bw for your important traffic.

What exactly are you trying to do or stop?

Re: Site2site VPN QoS question

What I want to do is prioritize the ERP traffic in our 3M link, I don't care how much bandwidth it need, just want to give priority to this kind of traffic.
