Connection Plug-ins

  • httpapi - New connection method that simplifies connections to platform-specific

APIs such as Arista eAPI and Cisco NXAPI. This method replaces connection: local with connection: httpapi and then specifying the specific platform via the ansible_network_os variable.

Modules

  • net_get - downloads a large config file to target network device with SCP/SFTP
  • net_put - copies a large config file to target network device with SCP/SFTP
  • netconf_get - fetches the configuration and state data from remote NETCONF enabled network

device/host

  • netconf_rpc - executes generic NETCONF RPC (remote procedure call) commands that are

defined by NETCONF standard as well as proprietary RPC-based NETCONF capabilities supported by the remote network device/host

New for Ansible Network Automation

Ab Abstrac act

WWT's Advanced Technology Center has many environments that can be accessed by customers and internal engineers to get hands-on exposure to the newest technologies. Maintaining and managing these labs absolutely requires automation and Ansible is a great choice. This webinar will explore the Ansible use case in WWT's deployment of Cisco DNA Center (DNA-C) / SD Access labs and WWT's newly released DNA-C Ansible Modules developed to aid in the automation of environment provisioning.
