About NX-API REST
NX-API REST
In Release 7.0(3)I2(1), the NX-API REST SDK has been added.
On Cisco Nexus switches, configuration is performed using command-line interfaces (CLIs) that run only on the swtich. NX-API REST improves the accessibility of the Cisco Nexus configuration by providing HTTP/HTTPS APIs that:
-
Make specific CLIs available outside of the switch.
-
Enable configurations that would require issuing many CLI commands by combining configuration actions in relatively few HTTP/HTTPS operations.
NX-API REST supports show commands, basic and advanced switch configurations, and Linux Bash.
NX-API REST uses HTTP/HTTPS as its transport. CLIs are encoded into the HTTP/HTTPS POST body. The NX-API REST backend uses the Nginx HTTP server. The Nginx process,and all of its children processes, are under Linux cgroup protection where the CPU and memory usage is capped. If the Nginx memory usage exceeds the cgroup limitations, the Nginx process is restarted and the NX-API configuration (the VRF, port, and certificate configurations) is restored.
