Hi Guys, For the Cisco gurus.Could someone please give me a lead on how I can prioritize and test WebEx, Skype and some two websites on Cisco equipment. My set up is such that the link goes to a Cisco 1941 router>Cisco ASA 5505>Cisco Catalyst Switch 2960>Computer. Thanks!
If your link is terminated on Ethernet to the cisco, then its no use prioritizing. The router will never sense congestion on the 100mbps interface and therefore not employ QOS. But your ISP should be able to prioritize your inbound traffic for you.

Tony, I beg to differ. Cisco supports QoS on Ethernet interfaces - using something called Hierarchical QoS - parent policy to define interface bandwidth and child policies to prioritise applications. You can start with the example on the link below: http://www.networkengineerblog.com/2011/03/qos-hierarchical-class-based-weig... You might have to start with the router and also do something on the ASA Kind regards, Bernard On Mon, Sep 12, 2011 at 3:14 PM, Tony Gacheru <tonygacheru@gmail.com> wrote:

David, Though they seem to disagree, Tony and Bernard have both provided you with the solution :) In your case, am assuming that your ISP; 1. Has sufficient Internet capacity from their upstream, 2. Is rate-limiting you at your subscribed capacity. Now, what Bernard has suggested is mostly effective for up-link(outbound) traffic only. It will not, however, greatly enhance your applications' performance as the return packets via your down-link may still be delayed. To achieve the best results, QoS must be implemented at all points of congestion/bandwidth limitation. You need to talk to your ISP and ask them to shape the down-link traffic for you because your packets are queued on their routers/bandwidth manager before they are released to get to you. On your end, please follow the guide from Bernard to shape your up-link traffic. R, On 14 September 2011 22:59, Bernard Wanyama <bwanyama@eis.co.ug> wrote:

Benard, I take back my explanation after reading the article. But the down side to this work-around is you would be dropping your own traffic when there is a chance the isp might have accepted the excess.

Hi, There is an opportunity to 'be your own ISP' in terms of QoS shaping because the two intermediate devices - Cisco ASA and Cisco router are back-to-back and within your control. The ASA can shape downstream for the Cisco router. Kind regards, Bernard On Thu, Sep 15, 2011 at 9:15 AM, Tony Gacheru <tonygacheru@gmail.com> wrote:

Bernard, I was not implying that cisco doesn't support QOS on Ethernet interfaces. What I meant is if your isp is giving you say 4mbps internet link and interface to your cpe is Fast Ethernet(100mbps), when your 4mbps pipe is full the cpe doesn't see this congestion as its communicating to the adjacent device at 100mbps. So even when QOS rules are there it doesn't enforce them since in essence there is enough capacity to pass all traffic.
