I have crafted and applied some rules which I thought would prioritize traffic from an 871w (via ADSL) to one specific host. The idea is that any traffic destined to this host should be prioritized over all other traffic. What is your upstream connection? If you're using PPPoE, you won't

Hi, you should use hierarchical QoS. First of all you should shape the output traffic down to the upstream speed, then you can use the llq inside the shaped class: http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a00800b2d29.shtml BR, A. On Tue, 24 Mar 2009, Ivan

First, thanks to those who pointed out my (should have been obvious) error where I named the access-list qos1 but then tried to reference it with al-qos1. When you're looking for a big problem it's easy to overlook the obvious. On Tue, 2009-03-24 at 12:56 +, Tim Franklin wrote: On Tue, March

Hi. So just a final question, would the solution have worked if it was on a regular interface? I just want to make sure I had the right idea. Yes, in this case the ATM-interface where the PVC lives. But the PVC must be something else than the default ubr class of service. The U in UBR stands

Hi. Which direction are you trying to prioritize? In the first post the policy were on the Dialer0-interface (traffic from LAN towards DSL), but in the last post it's on the Fa4-interface (traffic from DSL towards LAN). I assume it's the first one because there is less point shaping when going
