The Site Hierarchy selector in Catalyst Center Global Manager offers an aggregated view of all sites across different controllers. When multiple controllers share the same site (for example, Global/USA/East Coast), those sites are combined and presented as a single node in the site selector. The content displayed on the pages will be filtered based on the site that you select. An ufiltered view is also available.

The Site Hierarchy selector lists the first 100 nodes at each level. You can search for a specific site by entering a string and then click Enter or the Search button to initiate the search.

Refresh site hierarchy

There are effectively three scenarios to trigger a refresh of site hierarchy:

1. If there any updates on the sites in any of the controllers, you need to manually click the Refresh button in the site selector to reload the data from all the controllers.

2. If any updates on the controller’s reachability, such as updates on the controller or changes in reachability (for example, a controller becoming reachable or unreachable), then a manual Refresh is required in the site selector.

   Note	Selecting a site will reflect the network health and alerts data on the Overview dashboard, as well as the other second-level pages data. The network health and alerts are specific to each site, whereas the controller health is not site-specific.

3. In case of any error while populating the site data, an error count shows up in the bottom bar next to the Refresh.

The site selector does not automatically refresh for all changes; it only automatically refreshes the controller's sites in response to specific events such as:

• Controller enrollment with toast notification refresh.

• Unenrollment with toast notification refresh.

For these events, there's no need to manually click the Refresh button. In contrast, an on-demand refresh in the Catalyst Center Global Manager site selector is required when there are changes to the sites on the controller side, such as adding, deleting, or modifying sites.

The Catalyst Center Global Manager Overview page includes controller health and additional details about individual controllers.

When you log in to Catalyst Center Global Manager after adding controllers, Catalyst Center Global Manager starts rendering the data on the Overview page progressively. You can see a progress bar on the Overview page when the data loads incrementally as Catalyst Center Global Manager receives data from the enrolled controllers. This process is known as progressive loading.

Note	The total loading time of a page may differ based on the response time of each controller.

After all the enrolled controllers responded with data, the progress bar turns green. The progress bar disappears within 15 seconds after the data load is complete.

Note

If there is any error in the data fetching from the enrolled controllers, then the progress bar with error alerts will be shown on the page. You can mouse over to see how many controllers have responded. You can further drill down the details about the individual failure by clicking the loading status icon located near the date and time to view the specific failure details for each dashlet in the Overview page.

Note

Click Refresh to update the information displayed, ensuring you have the most current status of your network devices and components. This will provide you with the latest data on device health, performance, and any ongoing issues. Click Customize to rearrange the dashlets within the different sections of the Overview page.

The Alerts feature in Catalyst Center Global Manager allows you to view and explore details about alerts that require your attention. This includes information on different alert types and analytics, highlighting the top site groups and segment types of individual alert.

To view the alerts, navigate to the Catalyst Center Global Manager dashboard and click Alerts. Then the data gets loaded on this page progressively as it receives the data from the enrolled controllers.

The alerts are categorized into four levels:

• Critical

• Major

• Minor

• Informational

To see more information about a specific alert, click the alert type name on Alert types to cross-launch or navigate to their respective controller.

The Alerts page also gives information on:

• Analytics- Analytics shows the top site groups and top segment types.

• Users & Roles- Catalyst Center Global Manager uses both users and roles to manage access. Each user is assigned roles to access controller functionality.

  • Role Based Access Control- Role-Based Access Control (RBAC) in Catalyst Center Global Manager currently supports only the default roles: super-admin-role, observer-role, and network-admin-role. Custom role creation is not supported. Additionally, the user experience in Catalyst Center Global Manager may be impacted if there is a mismatch in permissions for the same user between Catalyst Center Global Manager and Catalyst Center. For example, if a user in Catalyst Center Global Manager does not have identical privileges in Catalyst Center due to site-based restrictions or custom roles, the Catalyst Center Global Manager may display limited data based on the user's access privileges.

    Also, accessing Catalyst Center Global Manager with a custom role or a site-based user from Catalyst Center is currently not supported, which may result in a suboptimal user experience.

    • The SUPER-ADMIN-ROLE has full control over the Catalyst Center Global Manager deployment, with all access permissions enabled.

    • The OBSERVER-ROLE has read-only access and cannot view certain sensitive data within the system settings.

    • The NETWORK-ADMIN-ROLE is a general-purpose role that does not have the capability to alter system configurations.

    On installation of Catalyst Center Global Manager, a user with super-admin privilege is created. The user in super-admin role will have the ability to create local users on Catalyst Center Global Manager.

  • External Authentication- Catalyst Center Global Manager supports external Authentication, Authorization and Accounting (AAA) servers for access control. If you are using an external server for authentication and authorization of external users, you should enable external authentication in Catalyst Center Global Manager. The default AAA attribute setting matches the default user profile attribute.

    Catalyst Center Global Manager enables external authentication with either AAA–RADIUS/TACACS or Cisco ISE server type. The external authentication process disables local user authentication.

    Note

    If external authentication is enabled on a specific Catalyst Center and it is integrated with Catalyst Center Global Manager, any cross-launch to that Catalyst Center fails and data specific to this controller is not fetched if the user has not logged in at least once using their external authentication credentials. Users must log in to Catalyst Center at least once before they can view any controller-specific data in Catalyst Center Global Manager or perform a cross-launch.
