Supported SR-TE policies and RSVP tunnels
Crosswork Network Controller traffic engineering supports the visualization and provisioning of a variety of SR-TE policies and RSVP tunnels. It simplifies service provisioning by exposing YANG model-based forms in its UI and providing APIs for integration with external systems, while Cisco NSO acts as the underlying provisioning engine.
Additionally, Crosswork Network Controller can discover and visualize pre-existing services that it did not create (such as brownfield service implementations) using telemetry and interaction with the SR-PCE. These services will be marked as unmanaged in Crosswork Network Controller. To modify these services, administrators can use a combination of device CLI, NSO's service models or APIs, the Crosswork Network Controller UI tool set, and in some case scripts to migrate pre-existing services from being un-mamanged to being managed.
Operators can collaborate with Cisco CX Professional Services or leverage resources and articles on the Cisco DevNet to customize or expand the capabilities of Crosswork Network Controller. This can include developing custom function packs tailored to their specific use cases.

Crosswork supports the use of Role-based Access Control (RBAC) to limit not only what functions a user can perform, but also on which devices they are allowed to perform those functions, see the "Cisco Crosswork Network Controller Administration Guide". |
