Chapter 5. Off-Box Programmability and Automation with Cisco Nexus NX-OS

Off-box programmability and automation are tools that run outside of the network equipment. Off-box programmability allows the network to be managed holistically or as part of an automation or orchestration solution. Off-box programmability provides a pathway for the network to be leveraged in Cloud operational models.

Off-box Cisco Nexus solutions include an API, named NX-API, that provides full configuration and monitoring of the switch. Additionally, NX-OS supports next-generation automation tools, including Puppet, Chef, and Ansible. NX-API serves as the interface that enables Nexus solutions to participate in continuous integration/continuous delivery software development ...
