Episode Description:
For years we have tested networks the same way, with ping. "Can you ping it?" "It's pingable?" "Uh oh... I lost a ping?" All statements you've undoubtedly heard, and said yourself. The problem is, 'ping' doesn't actually tell you much about the state of your network. Ping doesn't tell you if your routing protocols are working as expected. Ping doesn't tell you if you are seeing interfaces flapping. Ping doesn't tell you if you have a memory leak that will cause an outage in the near (or distant) future. Ping is a terrible network test tool...but we have a better one now.
pyATS, or Python Automation Test Systems, is a free network testing framework from Cisco with Open Source roots. With pyATS, you can actually test your network and answer questions like the ones ping failed miserably at. Start by profiling your network to learn what protocols are running, and their current state. With the profile, you now have a baseline of platform state that you can track overtime and monitor for deviations that hint at an underlying problem. Build test cases to run following changes to ensure the network is working before you get the call from the application team. Tests can be as simple as verify count '3' 'ospf neighbors' on device 'core1' . Join this session to learn all about pyATS, and how you can get started today!
