About this repository

This repository has a Python package to automate tests on Arista devices.

  • The package name is anta, which stands for Arista Network Test Automation.
  • This package (or some functions of this package) can be imported in Python scripts:
    • To automate NRFU (Network Ready For Use) test on a preproduction network
    • Or to automate tests on a live network (periodically or on demand)

In addition, this repository has also Python scripts to:

  • Test devices
  • Test devices reachability
  • Collect commands output from devices
  • Collect the scheduled show tech-support files from devices
  • Clear counters on devices
  • Clear the list of MAC addresses which are blacklisted in EVPN

This content uses eAPI (EOS API). You can find examples of EOS automation with eAPI in this repository.

Tests available in the python package anta

The tests are defined in functions in the python package anta:

  • Each function returns True, False or None (when it can not run properly)
  • The overview.md file has an overview of the functions documentation

Requirements and installation

Please see the requirements and intallation documentation for the requirements and installation procedure.

Repository usage

Once you are done with the installation, you can use the anta package and the scripts.

How to use the anta package

Have a quick look to the package documentation:

  • The overview.md file is an overview of the anta package documentation
  • The tests.md file is a detailled documentation of the anta package

Here's how we can import and use the functions of the anta package:

>>> import ssl
>>> from jsonrpclib import Server
>>> ssl._create_default_https_context = ssl._create_unverified_context
>>> USERNAME = "arista"
>>> PASSWORD = "aristatwfn"
>>> ENABLE_PASSWORD = "aristatwfn"
>>> IP = "192.168.0.12"
>>> URL=f'https://{USERNAME}:{PASSWORD}@{IP}/command-api'
>>> switch = Server(URL)
>>> from anta.tests import *
>>> dir()
>>> help(verify_eos_version)
>>> help(verify_bgp_evpn_state)
>>> help(verify_interface_discards)
>>> verify_eos_version(switch, ENABLE_PASSWORD, ["4.22.1F"])
>>> verify_bgp_ipv4_unicast_state(switch, ENABLE_PASSWORD)
>>> exit()

How to use the scripts

How to tests devices

  • Update the devices inventory with the devices IP address or hostnames.
  • Update the file tests.yaml to indicate the tests you would like to run. Some tests require an argument. In that case, provide it using the same YAML file.
  • Run the python script check-devices.py.
    • This script imports the python functions defined in the directory anta.
    • These functions defined the tests.
  • Check the result in the output file.
vi devices.txt
vi tests.yaml
./check-devices.py --help
./check-devices.py -i devices.txt -t tests.yaml -o output.txt -u username
cat output.txt

How to test devices reachability

vi devices.txt
./check-devices-reachability.py --help
./check-devices-reachability.py -i devices.txt -u username

How to collect commands output

  • Update the devices inventory with your devices IP address or hostnames.
  • Update the EOS commands list eos-commands.yaml you would like to collect from the devices in text or JSON format.
  • Run the python script collect-eos-commands.py.
  • Check the output in the output directory.
vi devices-list.text
vi eos-commands.yaml
./collect-eos-commands.py --help
./collect-eos-commands.py -i devices.txt -c eos-commands.yaml -o outdir -u username
ls outdir

How to collect the scheduled show tech-support files

vi devices-list.text
./collect-sheduled-show-tech.py --help
./collect-sheduled-show-tech.py -i devices.txt -u username -o outdir
ls outdir

How to clear counters

vi devices-list.text
./clear-counters.py --help
./clear-counters.py -i devices.txt -u username

How to clear the MAC addresses which are blacklisted in EVPN

vi devices-list.text
./evpn-blacklist-recovery.py --help
./evpn-blacklist-recovery.py -i devices.txt -u username

Devices testing demo

To test devices, once you are done with the installation, you simply need to indicate:

  • Your devices name or IP address in a text file. Here's an example.
  • The tests you would like to run in a YAML file. Some tests require an argument. In that case, provide it using the same YAML file. Here's an example.
./check-devices.py --help
usage: check-devices.py [-h] -i INVENTORY_FILE -u USERNAME -t TEST_CATALOG -o OUTPUT_FILE

EOS devices health checks

optional arguments:
  -h, --help         show this help message and exit
  -i INVENTORY_FILE  Text file containing a list of switches, one per line
  -u USERNAME        Devices username
  -t TEST_CATALOG    Text file containing the tests
  -o OUTPUT_FILE     Output file
./check-devices.py -u arista -i devices.txt -o output.txt -t tests.yaml
Device password:
Enable password (if any):
