Manage Applications

Application management

Catalyst Center provides many of its functions as individual applications, packaged separately from the core infrastructure. This enables you to install and run the applications that you want and uninstall those you are not using, depending on your preferences.

The number and type of application packages shown in the Software Management window vary depending on your Catalyst Center release and your Catalyst Center licensing level. All the application packages that are available to you are shown, whether or not they are currently installed.

Some applications are basic that they are required on nearly every Catalyst Center deployment. For a description of a package, click the Currently Installed Applications link and place your cursor over its name.

Each Catalyst Center application package consists of service bundles, metadata files, and scripts.


Note

  • Avoid using any CLI command for package management activities. If you encounter issues with package install or upgrade tasks in Catalyst Center, contact Cisco TAC for assistance.

  • From the Software Maintenance window, you can upgrade to the latest available Catalyst Center release. For upgrade instructions, see the Cisco Catalyst Center Upgrade Guide.

Download and install applications

Catalyst Center treats individual applications as separate from the core infrastructure. Specifically, individual packages for applications can be installed to run on Catalyst Center.

Installing and deploying application packages may take time, so schedule it during a maintenance period for your network.

Before you begin

Only a user with SUPER-ADMIN-ROLE permissions can perform this procedure. For more information, see About user roles.

Procedure

Step 1

From the main menu, choose System > Software Management.

Important

 

At this point, Catalyst Center performs a connectivity check. If there is a connectivity issue, the Software Management window won’t display the applications that are currently available.

Step 2

At the bottom of the window, choose which applications to install.

You can either

  • Select all applications: Click Select All.

  • Individual application: Check the check box.

Note

 

View more details about an available application by clicking View Details in any application card.

Step 3

Click Install.

Step 4

After Catalyst Center completes a dependency check, click Continue.

The window displays a progress bar for each application that's being installed. The Software Management window updates after all the applications have been installed.

Step 5

Click Currently Installed Applications and confirm that the selected applications are installed.

Package download and upgrade event notifications

You can receive a notification whenever a package download or upgrade event takes place. To configure and subscribe to these notifications, complete the steps described in the Work with Event Notifications topic of the Cisco Catalyst Center Platform User Guide. When completing this procedure, ensure that you select and subscribe to the SYSTEM-SOFTWARE-UPGRADE-v2 event.

Notifications are generated and sent when:

  • The download of a package upgrade failed. This failure typically happens because your Catalyst Center appliance doesn't have the necessary disk space or you're attempting to download a corrupted package.

  • The installation of a package upgrade failed (possibly because the service that's associated with the package is currently down).

  • The download or installation of a package upgrade succeeded.


    Note

    A notification is sent only if the previous attempt to complete the operation failed.

View an upgrade summary report

From the Upgrade Summary Report slide-in pane, you can view the results of the latest upgrade of Catalyst Center and its applications. This report allows you to:

  • Identify the previous Catalyst Center version that was installed on your appliance.

  • Determine when the upgrade took place.

  • In the Post-check tab, see whether the post-upgrade checks Catalyst Center makes completed successfully. If a problem occurs for a particular check, click its information (i) icon in the Issues column for a description of the problem.

  • In the Packages tab, view the application packages that were upgraded and their current version number.

Complete the following steps to open this report.

Procedure

Step 1

From the main menu, choose System > Software Management.
