    Hi All,



    I've problem with my 3com switch 2226-SFP Plus, I've 3 Vlans on my network in one of these i've also voip packets.



    I need to tag my voip packets that come in to the switch inside an untagged port with dscp code ef  with VID and with priority CoS .



    At now my switch don't set the CoS, so all packets that came in an untagged port are tagged with the corret VID but they have priority 0 .



    I thinks Switch doesn't read dscp code on ingress packet.



    (In web configuration in the Dscp to Cos view, mapping Dscp--> Cos is correct, but doesn't work).



    Are there any suggestion ? What should I do to tag priority code on Vlan packet ?



    Really thanks



    Tgw!



    p.s



    I think i've the last software version 1.0.1.15
