A simple PoC demonstrates how a few lines of Python code can retrieve the switch VLAN configuration from Google Sheets and use Arista’s eAPI to implement changes to the switch. A few more lines of code enable a constant track of changes in the spreadsheet. This presentation will demonstrate the power of network programmability for automation and orchestration challenges.
