I have an 871, I would like to know if after I setup another vlan if I can give that vlan priority? I would like to hook up my Vonage up to that vlan. If anyone know or can point me to the right documents that would be a big help.

Hello Phil,

if I understood correcly you would like to give priority to traffic originated in one vlan.

the QoS tools can provide a better treatment to the traffic originated in one vlan over the WAN link

you need to use class-maps to define traffic types


let's suppose the ip subnet associated to the vlan you want to be treated better is

access-list 11 permit

class-map preferred_traffic

match access-group 11

policy-map wan_cbwfq

class preferred_traffic

bandwidth percent 60

this has to be applied to wan interface with

int type x/y

service-policy out wan_cbwfq



Hope to help

Thank you I will give this a try. We do a lot of downloading and I would like the Vonage to take priority over everything else on the network. Do you think that putting it on its own vlan is a good idea?

I'm not sure what you mean 'given the vlan priority, can you explain what you need to happen?
