The application catalog in Cisco SD-WAN Manager provides visibility and control of applications running in your Cisco Catalyst SD-WAN environment powered by SD-AVC. For more information about SD-AVC, see Cisco SD-AVC User Guide. The application catalog includes applications ranging from business productivity apps like Office 365 or Google Workspace to social media platforms, cloud platforms, and customer-created applications.

The application catalog is a central place to take care of all operation tasks related to applications, capabilities like updating applications and cloud SaaS feeds from different sources, creating custom applications, viewing applications in different groups, creating an application list and many more. The feature optimizes network connectivity based on the specific requirements of different Kubernetes services.

Note	You can use custom applications in the same way as any other protocol when configuring policies using policy groups or using centralized policies. For more information on configuring policies using Policy Groups, see, Group of Interest - Policy.

The Application Catalog tab has the following features:

• Overview

• Applications

• Application Source Settings

• Discovered Application

• Application List

• Configure SD-AVC

• Configure Cloud Connection

• Cloud Sourced Applications

Adding Applications to the Application Catalog

A cloud-sourced application may match some of the same traffic as an existing application. In some cases, Cisco SD-WAN Manager prompts you to take action to resolve any conflicts.

To fully utilize the capabilities of application catalog, the following conditions must be met:

• Enable SD-AVC on the Administration > Settings page.

  Note	For Cisco Cloud-hosted overlays provisioned in Cisco Catalyst SD-WAN Control Components Release 20.10.x and later releases, the SD-AVC service and Cloud Connector are enabled by default. For more information see, Cisco SD-AVC.

• Enable SD-AVC Cloud Connector to use SaaS feeds for enhanced application classification (Optional, but recommended).

View the applications associated with your cloud account including the applications you create and the default applications on Cisco SD-WAN Manager.

1. From the Cisco SD-WAN Manager menu, choose Configuration > Application Catalog > Applications.

   A list of applications associated with your Cisco SD-WAN Manager appears.

2. Choose an application attribute from the Select Application Attributes drop-down box. For example, Application Source.

   From the Choose Filter drop-down choose a filter to view only the relevant applications.

1. From the Cisco SD-WAN Manager menu, choose Configuration > Application Catalog > Applications > Custom Application

2. Enter Application name.

   Configure the following:

   Field	Description
   Application Name	Enter a name for the application list.
   Server Names	Enter the server names. The names specify the fully qualified domain names or regex starting with '*' but not ending with '*', or both separated by commas. For example, *.customapp.com, customapptest.com, *appcustom.
   Application Family	Choose the application family. The options include instant messaging, game, mail, routing, and so on.
   Application Group	Choose the application group. The options include flash-group, ipsec-group, concur-group, and so on.
   Traffic Class	Choose the traffic class. The options include multimedia-conferencing, network-control, real-time-interactive, and so on. Note   This attribute is used to categorize network traffic into different classes based on specific criteria like source and destination IP addresses, port numbers, etc. Traffic classes are crucial in the traffic matching process because they enable the Cisco Catalyst SD-WAN to identify and sort traffic, which helps in efficiently managing bandwidth and resources. When setting up the policy group workflow, different traffic classes can be allocated different priorities.
   Business Relevance	Choose the business relevance from the drop-down list. The options are: Bronze Gold Silver Note   This attribute is used to specify the priority of network traffic based on its relevance to business operations. For example, traffic related to critical business applications can be assigned a higher relevance, and therefore, a higher priority. This ensures that important traffic gets the resources it needs for optimal performance.
   IPv4 Address	Enter the IPv4 addresses separated by commas. Subnet prefix length is 24 to 32.
   Ports	Enter the port number or range or both separated by a space. For example, 1 2 10-20.
   L4 Protocol	Enter L4 protocol. The options are: TCP UDP TCP-UDP

3. Click Save.

1. From the Cisco SD-WAN Manager menu, choose Configuration > Application Catalog.

2. Click Cloud-sourced Application.

3. Choose one or more cloud-sourced applications by clicking the check box adjacent to the applications.

4. Click Apply Application(s) and choose Apply Selected Application(s).

   A cloud-sourced application may match some of the same traffic as an existing application. If this creates a conflict, Cisco SD-WAN Manager prompts you to take action to resolve any conflicts. For information about the logic, see Information About Cloud-Sourced Applications.

5. If the policy conflict pop-up window opens, choose one of the following:

   • Fix Conflicts: Opens the Conflicts tab to enable you to update the policy.

   • Click Manage Cloud-Sourced Application Conflicts to add cloud-sourced applications after fixing the policy conflicts.

   • Ignore and Apply: Defer resolving conflicts that affect policies and add cloud-sourced applications to application catalog.

   Note	To remove cloud-sourced applications from the application catalog, contact Cisco technical support.

• Unified Network Management: Cisco SD-WAN Manager gives the ability to add Kubernetes clusters and it discovers any applications running on them.

• Enhanced Visibility: The Cisco SD-WAN Manager and Kubernetes clusters integration provides complete visibility over both network infrastructure and application definitions, making it easier to identify and resolve issues.

• Improved Performance: Cisco Catalyst SD-WAN’s ability to optimize network traffic, combined with direct visibility over Kubernetes resources, results in improved application performance.

• Greater Efficiency: The network management based on application requirements and Kubernetes services leads to greater operational efficiency.

• Advanced Security: The Cisco SD-WAN Manager and Kubernetes clusters integration provides more robust security for both network and application layers.

• Cloud SaaS feeds provide real-time data on cloud application classification. Cisco SD-WAN Manager uses this information to make intelligent decisions about routing and optimizing traffic to ensure the best possible performance for these applications.

• The Application classification is enhanced and up-to-date with latest Cloud SaaS feeds.

1. From the Cisco SD-WAN Manager menu, choose Configuration > Application Catalog > Application Source Settings.

2. In the Cloud SaaS Feeds table, you see a list of cloud application feeds.

   Note	Only if you've enabled SD-AVC and Cloud connections, you'll see the list of cloud SaaS feeds.

3. In the Actions column, click the ... icon adjacent to the respective cloud SaaS feed row.

4. Click Enable to view cloud SaaS feeds for the application of your choice.

   Note	Choose Disable so that the application classification doesn't use the Cloud SaaS feeds and instead uses NBAR classification logic.

1. From the Cisco SD-WAN Manager menu, choose Configuration > Application Catalog > Application Source Settings.

2. In the Action column, click ... icon and choose View Feeds.

3. In the the View Feeds page, you see detailed information regarding the particular cloud SaaS feeds.
