What is Model-Driven Telemetry Model-driven telemetry is a new approach for network monitoring in which data is streamed from network devices continuously using a push model and provides near real-time access to operational statistics.

What is Guest Shell? Cisco IOS-XE devices (as of release 16.6.1) come with a guest shell, which is essentlially a virtualized Linux (CentOS) environment.

Introduction In this post, we walked through a number of SD-WAN API’s using POSTMAN. As a follow-up, we will explore in today’s post some Python scripts that implement these APIs.

Introduction SD-WAN is a software-defined approach to managing the WAN. In the past, MPLS networks were used to ensure reliable connectivity between users connecting at the branch to applications running on servers in the datacenter.

Introduction In this blog post, we used Ansible to interact with our IOS XE devices through a module called ios-modules.
