We are moving our network from point to point to metro ethernet (MVLS). My Internet provider allows for two vlans: priority/real-time traffic, and all other traffic. The real-time traffic would be items like ICA, DNS, LDAP, DS, and so on.
Creating vlans is not a problem. My issue is how to assign certain traffic (tcp ports) to particular vlans? From what my ISP tells me, the ISP's systems read my vlans and will prioritize the vlans I tell them are real-time. So do I use QOS to create traffic profiles for vlans? Not having done this, I'd appreciate some guidance and recommendations.
All of my sites and HQ have 3com 5500 series switches.
