This link has the slides that I presented as part of lightning talk at Devops Days India, 2016. In the slides, I have tried to capture how automation in networking area is evolving. I attended first day of the conference and it had a pretty decent collection of talks in Devops area.
I had covered basics of Arista EoS and vEoS in my previous blog. Arista’s Eapi gives programmatic approach to manage Arista devices. Arista’s Pyeapi Python library is built on top of Eapi. In this blog, I will cover the following:
- Pyeapi library
I have used Arista vEoS for trying out all examples below without needing a physical Arista device. That shows the power of virtual device.
There is lot of similarity between Arista’s Eapi and Cisco’s NXAPI. I covered NXAPI in 1 of my earlier blogs. Arista’s Eapi is equivalent to Cisco’s NXAPI, Arista’s Pyapi library is equivalent to Cisco’s Pycsco library. Arista’s Eapi provides http/https access to the Arista router/switch through which we can send standard CLI commands and the output is received in JSON/XML formatted output. There is no need to do screen scraping with this approach, this makes it devops friendly. Arista’ Pyeapi is available as a github project.
To enable Eapi in Arista device, do “management api http-commands” in config prompt. Following is the output in my Arista vEoS switch:
