Important notes
Behavioral change: NSO keepalive configuration now required for stable RESTCONF integration
Before using Crosswork Network Controller 7.2.1, you must update the NSO keepalive configuration.
In earlier deployments, Crosswork Network Controller interactions with the NSO service-state-changes RESTCONF API could leave sessions hanging. Over time, these inactive sessions could consume all available NSO sessions and cause communication failures between CNC and NSO.
To prevent this issue, configure NSO keepalive settings in the ncs.conf file for all deployments, including Standalone NSO and NSO LSA. This configuration allows NSO to detect closed client connections and automatically clean up inactive sessions.
For configuration steps, refer to the Install the Cisco NSO function packs section in the Crosswork Network Controller Release 7.2.1 Patch Installation Workflow documentation.
For instructions on installing the Crosswork Network Controller 7.2.1 patch, see Crosswork Network Controller Release 7.2.1 Patch Installation Workflow.
