Hi Gary, I've read through your email again and answered my own question.
My next question would be, have you given thought to the upstream sync-speed? Our testing highlighted that when QoS was applied to the pvc, it didn't seem to function properly unless we applied a vbr-nrt bitrate configuration which matched the upstream sync-speed e.g. interface ATM0 pvc 0/38 vbr-nrt 832 832 tx-ring-limit 3 encapsulation aal5mux ppp dialer dialer pool-member 2 service-policy output dsl-out max-reserved-bandwidth 100 Steven Steven McCrory Senior Network Engineer Netservices PLC Waters Edge Business Park Modwen Road Manchester, M5 3EZ www.netservicesplc.com -----Original Message----- From: cisco-nsp-boun...@puck.nether.net [mailto:cisco-nsp-boun...@puck.nether.net] On Behalf Of Steve McCrory Sent: 01 May 2009 12:21 To: gie...@snickers.org; cisco-nsp@puck.nether.net Subject: Re: [c-nsp] QoS Strategy for Cisco 877 Hi Gary, Configuring QoS on Cisco 877 routers is actually at the heart of one of our products. Can I ask what queuing method you are using, are you using CBWFQ or Priority queuing?

Giesen Sent: 30 April 2009 21:17 To: cisco-nsp@puck.nether.net Subject: [c-nsp] QoS Strategy for Cisco 877 Guys, I've been trying a bunch of different methods, but nothing seems to achieve what I want. Ideally I'd like to use Priority Queueing (or something that operates the same) on the ATM0 interface of a Cisco 877. I have 3 classes of traffic: Telnet/SSH/ICMP/Management - High Priority General Data - Default Priority IP Video Camers - Low Priority Normally I would just use a priority-list/priority-group, but I can't seem to apply it to either the ATM0 interface or the ATM0.33 interface (and I have also tried applying it on the PVC under the subinterface). I would like all packets in the high priority queue to be serviced first, then all packets in the default priority, and if there's any bandwidth leftover, service the low priority queue. I would prefer not to have to define minimum and maximum bandwidth for each queue (I don't want any hard queues/bandwidth limits, I would like all available bandwidth to be used by any particular queue as long as the queues above it are serviced). Can anyone recommend a QoS strategy/configuration for this that will work on the ATM0/DSL interface (no PPPoE) on a Cisco 877?
