In this use case we review the standard traffic classes (called QoS profiles) and recommend the default mapping into those classes. We also review how you can edit a QoS policy (and rule) to define application level matching within these standard classes. Colt sets up and deploys the following seven QoS profiles for your organisation’s class of service. | PROFILE NAME | RECOMMENDED USE | FORWARDING CLASS | TRAFFIC CLASS | | ---------------------- | ------------------ | ---------------- | ------------- | | Expedited Forwarding-1 | Voice | FC4 | Premium+ | | Expedited Forwarding-2 | Video Conferencing | FC5 | Premium | | PROFILE NAME | RECOMMENDED USE | FORWARDING CLASS | TRAFFIC CLASS | | ------------------- | --------------- | ---------------- | ------------- | | AssuredForwarding-1 | Priority Apps | FC8 | Enhanced+ | | AssuredForwarding-2 | Business Apps | FC9 | Enhanced | | PROFILE NAME | RECOMMENDED USE | FORWARDING CLASS | TRAFFIC CLASS | | ------------ | -------------------- | ---------------- | ------------- | | BestEffort-1 | Low Priority Apps | FC12 | Basic+ | | BestEffort-2 | Internet | FC13 | Basic | | BestEffort-3 | Local Guest Internet | FC14 | Basic | #### TO REVIEW QOS PROFILES: 1. Log in to the SD WAN portal. 2. In the Director Context, click the Config Templates tab. 3. Select the template you want to review QoS for. QoS profiles may be defined on its own template, which is called a service template. *CenturyLink creates your template and names it: \[your organisation’s name]-QoS.* 4. In the Networking tab, select Class of Service > QoS > Profiles. 5. To view how a profile is mapped to a forwarding class, click on the profile name.
{% hint style="info" %} **Note:** Colt recommends your organisation does not create addiitonal profiles or edit the forwarding classes or settings for the default profiles without a custom design review. To schedule a custom design review, contact your account representative. {% endhint %}
Colt uses the application identification functionality to identify most of your organization’s traffic and assigns it to the appropriate traffic class. In addition, Colt uses differentiated services code point (DSCP) values and zones to define traffic into the appropriate traffic class. The table below shows samples of how your traffic is matched to the forwarding classes.

{% hint style="info" %} **Note:** Colt names the rule either *Voice* or *GuestInternet*. Look for the appropriate name to monitor and view analytics for the rule. {% endhint %} You can take the following steps to edit a rule using the SD WAN app QoS feature. Rules are executed in priority order with the highest (or first) rule at the top and the lowest (or last) rule at the bottom. You can move rules by selecting them and moving them up or down the list. An app QoS policy (called the default-policy) was created by Colt during the onboarding process. You can have only one QoS policy, but you can edit the rules for that policy by following the instructions below. To configure app QoS policies and rules: 1. Log in to the SD WAN portal. 2. In the Director Context, click the **Config Templates** tab, select a template. 3. In the **Networking** tab, select **Class of Service > App QoS > Policies > Rules**. 4. From the **Organization** list, select an entity. 5. Select the checkbox next to an existing rule to edit.\
6. *In our example, we will edit Voice-SIP-RTP.*
7. Click the **Applications/URL** tab to review/edit the applications that are matched to this rule.\
8. To add a new application, click the **+ sign** and select the application from the list. You can also define a new custom application by selecting the **New Application** selection. 9. Click **OK**. #### APPLY THESE CHANGES TO YOUR BRANCHES 10. Click **Commit**.
11. From the **Select Template** list, select the related branches to commit either the new SD WAN rule or all rules. *We recommend you commit a template to just one branch to test your new rule before applying it to all the branches related to your template.*\
12. In the **View** column, click the **eye icon** to preview changes.
