You define uplink types in the Sites & Networks page.

An uplink type is a name for similar functioning uplinks. On the SCC, uplink types can be used across multiple sites and path selection rules can be created using these names. The name must be unique at a site (but it can be same across different sites) so that the system can detect which path selection rule uses which uplinks. Because path selection rules are global on the SCC, you are restricted to 8 uplink types.

Uplink types are the building blocks for path selection. You select the path preference order using the uplink types created, and it is used in various sites. Riverbed recommends that you reuse the same uplink types at different sites in order to label uplinks based on the preference for path selection. For example, you can label uplink types as primary, secondary, and tertiary based on the path selection preference. The uplink type can be based on the type of interface or network resource, such as Verizon or global resource of uplink abstraction that is tied to a network.
