Finally, click on the CoS Policy tab to attach policies to interfaces. In Figure 3, you can specify policies on the Node A and Node Z endpoints of a link. Note that only the CoS Policies that are applicable to the Node A router will be listed under the Node A Policy drop-down menu, and likewise for Node Z. Recall that in Create Policies for Classes, the user can specify a particular router or “[Any Router]” for each newly created policy.
