deployment of QoS over Ethernet interfaces in LAN

Dear All,

In our network we have deployed Qos consisting of CBWFQ incl. a priority Q (which runs voip and other 'premium' traffic).

Our network consists of a couple of LAN sites connected by WAN links of varying bandwidth (e.g. 32 Mb PVCs with a 2Mb serial link at one point, the congestion point)

At the moment Qos is only deployed on the outgoing interfaces of the 2mb serial WAN link, i am wondering is it worth it to deploy the same Qos on all the ethernet interfaces and the ATM interfaces between the two sites?

I initally thought that it would not be necessary because that is not the congestion point, however now i am thinking that a priQ on the fast ethernet intrefaces would also add some benefit to the voice service?

Thanks

Chris

Re: deployment of QoS over Ethernet interfaces in LAN

It's better to configure QoS through out the path since it will gaurantee the bandwidth required for that traffic flow.
