3. If you already have a Class of Service created that you want to apply that bandwidth limiting Rate to, you can skip this step and go directly to Step 4 below and edit that existing CoS and apply the Rate directly. In the example below, we'll create a new CoS called "Guest Class of Service" by going to Configure > Policy > Class of Service > Add

4. From the CoS definition screen, give your new CoS a Name, and then select the new Rate you have created by selecting it for either "Inbound" or "Outbound" or both, depending on how you wish to control and limit client traffic that will have this CoS applied, and click "Save"

5. For this new Rate and CoS to be applied, you will need to assign the new CoS that has the new Rate configured to a Role that will be applied for XCA clients.  In this example, we'll apply the "Guest Class of Service" to an existing Role called "Guest Access". To do this, go to Configure > Policy > Roles and double-click the "Guest Access" Role

6. In the Guest Access role definition screen, click on the "wrench" icon to edit the Class of Service that is defined for the "Guest Access" Role. In the "Use Existing CoS" drop down, select the "Guest Class of Service" you created in Step 4 above, and click "OK"

7. When you click "OK" in Step 6 above, you will be presented with the question shown below. If you wish to apply this adjusted Role to one or more AP Profiles, you may select "Yes" and do so in the screen that is shown next in Step 8, or you may select "Skip" and do so at another time

9. Now you have created a bandwidth limiting Rate of 5120Kbps called "Guest Rate Limit" and applied it to newly created Class of Service called "Guest Class of Service" and you have then applied that "Guest Class of Service" to the "Guest Access" Role.  Clients that are then assigned the "Guest Access" Role, will be limited to a bandwidth limit of 5120Kbps, both Inbound and Outbound as is shown below
