Configuring Optimization Default Service Classes
To configure the default set of WAN Optimization Service Classes, do the following:
Open the Service Classes table.
Continuing in the **Defaults** branch of the **Optimization** section of the **Configuration Editor**, click **+** to the left of the **Service Classes** branch label.
This opens the **Service Classes** table, displaying the default set of Service Classes.
This table is also a configuration form. You can use this form to configure (edit), delete, and add Service Classes to create a customized default set. The modified default **Service Classes** set and individual Service Class settings you configure are automatically applied as the defaults to any branch site included in the **Optimization** section tree.
You can also customize the Service Classes set and settings for each specific branch site. For instructions on customizing the Optimization configuration for a branch site, see the section, Configuring Optimization for a Branch Site.
2. To configure an existing Service Class, click Edit (pencil icon), in the **Edit** column of that class entry in the Service Classes table. This opens a pop-up **Edit** settings form for configuring the selected Service Class.
3. Configure the basic settings for the Service Class. The basic settings are as follows: - **Enabled** – Select this to enable the new Service Class. The class is enabled by default. - **Acceleration Policy** – Select a policy from the **Acceleration Policy** drop-down menu. The options are: \* **disk** – Select this policy to specify the appliance disk as the location for storing the traffic history used for compression. This enables Disk Based Compression (DBC) policy for this Service Class. Generally speaking, a policy of **disk** is usually the best choice, as the appliance automatically selects **disk** or **memory** as the storage location, depending on which is more appropriate for the traffic. \* **none** – Select this if you do not want to enable an Acceleration Policy for this Service Class. A policy of **none** is generally used only for uncompressible encrypted traffic and real-time video. \* **flow control only** – Select this policy to disable compression but enable flow-control acceleration. Select this for services that are always encrypted, and for the FTP control channel. \* **memory** – Select this policy to specify memory as the location for storing the traffic history used for compression. - **Enable AppFlow Reporting –** Select this to enable AppFlow reporting for this Service Class. AppFlow is an industry standard for unlocking application transactional data processed by the network infrastructure. The WAN Optimization AppFlow interface works with any AppFlow collector to generate reports. The collector receives detailed information from the appliance, using the AppFlow open standard (http://www.appflow.org).
For more information on AppFlow, please see the Citrix CloudBridge 7.4 Product documentation available on the citrix documentation portal http://docs.citrix.com/.
To view WAN Optimization AppFlow reports, select the Monitoring tab, and then in the navigation tree (left pane), open the WAN Optimization branch, and select AppFlow. See also, Monitoring Your SD-WAN Virtual WAN.
- **Exclude from the SSL Tunnel** – Select this to exclude traffic associated with the Service Class from SSL Tunneling. 4. Configure the **Filter Rules** for the Service Class. To edit an existing rule, do the following: a. In the Filter Rules table (bottom of form), click Edit (pencil icon) in the Edit column of the rule you want to edit. This reveals the Filter Rules settings for the selected Filter Rule.
b. Select the filter direction from the Direction drop-down menu. Select one of the following options: \* **BIDIRECTIONAL** \* **UNIDIRECTIONAL** c. Add or remove Applications in the **Configured** list. **To add an Application to the list**: Select it in the **Applications** list on the left, and then click the Add right-arrow (**>**) to add the group to the **Configured** list on the right. To add all of the **Applications** to the list at once, click the Add All double right-arrow (**>>**). **To remove an Application from the list:** Select it in the Configured list on the right, and then click the Remove left-arrow **(\<**). To remove all of the **Applications** from the list at once, click the Remove All double left-arrow (**\<\<**). d. Scroll down to reveal the truncated portion of the form. The **Filter Rules** settings section is somewhat long, so you will need to use the scroll bars to reveal the truncated portion of the form.
e. Enter the Source IP Address in the **Source IP Address** field. f. Click **+** to the right of the Source IP Address you just entered. This adds the specified IP Address to the **Source IP Address** table.
g. Specify whether to include or exclude the Source IP Address for this Filter Rule.
** Select the **Exclude checkbox to exclude the specified Source IP Address from this Filter Rule. Deselect the checkbox to include the address.
h. Enter the Destination IP Address in the **Destination IP Address** field**.** i. Click **+** to the right of the Destination IP Address you just entered. This adds the specified IP Address to the **Source IP Address** table.
j. Specify whether to include or exclude the Destination IP Address for this Filter Rule. Select the **Exclude** checkbox to exclude the specified Destination IP Address from this Filter Rule. Deselect the checkbox to include the address. k. Click **Apply**. This applies your modifications to the rule and hides the **Filter Rules** settings section. 5. (Optional) Customize the default **Service Classes** set. You can add or delete Service Classes to customize the default set, as follows: **- To remove an Service Class from the set:** Click the trashcan icon in the **Delete** column of a Service Class entry in the table to remove that entry. **- To add an Service Class to the set**: a. Click **+** to the right of the **Service Class** branch label. This displays the **Add** configuration form.
b. Enter the name for the new Service Class in the **Name field.** c. Configure the new Service Class. The steps for configuring a new Service Class are the same as for modifying an existing Service Class. For instructions, see the following steps, earlier in this section: "3. Configure the basic settings for the Service Class." "4. Configure the Filter Rules for the Service Class." d. Click **Add** to add the new Service Class to the default set and dismiss the **Add** configuration form. 6. (Optional, recommended) **Save** the configuration package.
For instructions on saving and loading a configuration package, see Naming, Saving, and Backing Up the MCN Site Configuration.
You have now completed the Defaults section configuration, and can begin configuring the Optimization sets and settings for the branch sites.
