All of the information I read about enabling CoS refers to a three tier setup, an access layer, dist. layer and edge. I am in a small environment that has only an access layer (EX4200 closet switches on each floor), which connect to a core switch (also EX4200) with ae interfaces. The core switch provides all L3 routing, access layer functions for some servers and also a dedicated ae interface to another location over our WAN link. My ultimate goal is to setup CoS for that link. In theory, I think I have to setup and define ingress filters for each interafce on the closet switches, in addition to the interfaces for the servers on the core switch. I then need to create and define schedulers and a scheduler map. I assign the scheduler map to the outgoing ae interface that is used for the WAN link. I know I'm missing something (or several somethings).
Also, when I definea firewall ingress filter, does each source-address have to be exact (/32)? Or can I define an entire vlan, such as x.x.x.0/24? I guess that means I want to definte these per vlan, I suppose. Confusion reigns!
Thank you in advance for any pointers.
