Tips

pyATS Tip: Use pyATS APIs, like get_platform_memory_usage() , to easily retrieve device performance metrics, such as memory usage, from network devices, which you can later use within your test cases. Example below 👇 from genie import testbed testbed = testbed.load("testbed.yml") device = testbed.devices["leaf1&

Ansible Resource Modules offer various states to manage network configuration sections effectively. For example use parsed to convert configurations into structured data, like so: --- - name: Ansible Modules - Resource Modules (Parse) hosts: leaf1 gather_facts: false tasks: - name: Parse the provided configuration cisco.ios.ios_l3_interfaces:

pyATS Tip: Customize SSH directly within the pyATS testbed using ssh_options. Ideal when needing to alter the algorithms used when connecting to older devices. Here is an example 👇 devices: leaf1: alias: leaf1 connections: cli: ip: 172.29.151.100 protocol: ssh ssh_options: -o KexAlgorithms=+diffie-hellman-group1-sha1 -o HostKeyAlgorithms=+ssh-rsa

Python Tip: Use product from itertools to flatten your nested for loops. Here is an example 👇 devices = ["192.168.1.1", "192.168.1.2", "192.168.1.3"] interfaces = ["Gi0/1", "Gi0/2", "Gi0/3"] # -- Using

Python Tip: Use pip-audit to check your local Python project dependancies for vulerabilities. Heres how 👇 # Install python -m pip install pip-audit # Scan pip-audit # or, if you have a requirements.txt file pip-audit -r requirements.txt # Output: # Found 2 known vulnerabilities in 1 package # Name Version ID Fix Versions # ---- -------

Python Tip: You can filter a dictionary against keys that are present in a list by using dictionary comprehension. Here’s an example 👇 vlans = { 100: "VLAN-100-HR", 200: "VLAN-200-IT", 300: "VLAN-300-Finance", } filter_ids = [100, 300] filtered_vlans = { vlan_id: vlan_name for vlan_id, vlan_

Python Tip: Use Python Set intersection to find common values between two sets. Here's an example 👇 vlans = {100, 200, 300} # Intersection of two sets using & vlans & {100, 500, 300} # Output: {100, 300}

Tip: If you're looking for a faster alternative to Netmiko for CLI scraping, consider using Scrapli. It offers various transport types, such as SSH2, which can significantly enhance speed. Here's a short example 👇 # Install: pip install scrapli from scrapli import Scrapli device = { "host": "

Python Tip: Append the variable with = to also show the variable name when using Python f-string's. Heres an example 👇 x, y, z = 1, 2, 3 f"{x} {y} {z}" # Output: # '1 2 3' f"{x=} {y=} {z=}" # Output: # 'x=1 y=
