QoS on Cisco 877, Dialer, ATM or PVC level?

Hi guys,

Can anyone please be so kind as to explain the best way of applying QoS on Cisco 877 router? I am really confused to which interface to apply the policy-map, Dialer, atm0 or atm PVC interface level. Some resources say to apply it on both Dialer and ATM but when I test it with VoIP after showing policy-map on both Dialer and ATM interfaces for instance Voice packets queue on one interface and signalling on a different one.

Please anyone help how to apply QoS in this scenario and best way for verifying it. Please ask for more details should you need to.

Many thanks,

Remi

Re: QoS on Cisco 877, Dialer, ATM or PVC level?

Hello Remi,

I would configure it on one interface only.

Start with the dialer if you are using PPPoA.

mark traffic on lan interface, create class-map based on DSCP or IP precedence marking and a CBWFQ service-policy.

If it does not work try on the ATM0.

Hope to help

Giuseppe
