You define site connectivity templates in the Sites & Networks page.

A site connectivity template is a container for one or more uplinks that are used at different sites. We recommend you use the site connectivity template if you have the same uplinks with common uplink properties at more than one site. Common uplink properties that are independent of a site configuration are defined in a site connectivity template. The template is then applied to a site, thereby creating a copy of the uplinks of the template to the site. After the uplinks are copied to a site, you must define the site-specific configuration for the uplinks. Any changes made to the site connectivity template don’t affect the sites that have uplinks.

Site connectivity templates enable you to define the characteristics of a site once and use it for multiple sites. For example, if you add a SteelHead to the network at a new site, you can choose a site template that defines the configuration for multiple sites. The site template includes a description that explains the intent of the configuration. This description is important because if a new network administrator has to make changes to the configuration, it will be clear what type of configuration it is and how it is used.
