eos_validate_state - Preview Integration with ANTA


eos_validate_state intergration with ANTA is in preview. Everything is subject to change. If you have any questions, please leverage the GitHub discussions board


eos_validate_state is a role leveraged to validate Arista EOS devices’ operational states.

eos_validate_state role:

  • Consumes structured EOS configuration file, the same input as the role eos_cli_config_gen. This input is considered the source of truth (the desired state).
  • Connects to EOS devices to collect operational states (actual state). This requires access to the configured devices.
  • Compares the actual states against the desired state.
  • Generates CSV and Markdown reports of the results.

Known limitations

  • Loose mode to ignore playbook errors is no longer supported in ANTA mode.
  • ANTA mode exclusively supports the newer “list-of-dicts” data models in the structured configuration file input. For further details, consult the AVD 4.x.x porting guides.



Subject to change. No commitments implied.

  • Provide a custom ANTA test catalog as a YAML file or by input variables.
  • Ability to exclude some interfaces from the report.
  • More tests!

Expected changes

  • You should expect faster execution, and if not please report on the GitHub discussions board
  • Hardware tests are now collapsed.
  • Some description of tests have been updated to be more precise.
  • Sorting of the test results is now done per device as opposed to per category.
  • Tests skipped by ANTA will be marked as SKIPPED in the final reports.
  • All tests will be removed from the catalog for a device flagged as undeployed using the host level variable is_deployed: false. Additionally, all tests take into account the is_deployed variable value and remove tests accordingly.


Tests can also be automatically removed from the catalogs depending on the structured configuration of the devices. ANTA is therefore not aware of these tests and they will not appear in the final report. For example, the AvdTestMLAG tests will not be present in the test catalog of a device that does not have an MLAG configuration in its structured configuration.

  • BGP tests will only run if service_routing_protocols_model is set to multi-agent in the structured configuration file.


Starting from version 4.30.1F, service_routing_protocols_model is preset to multi-agent by default on EOS devices.

How to run eos_validate_state in ANTA mode

  • Install the “anta” Python package (this is not part of the requirements.txt):

    pip3 install '
  • Run eos_validate_state playbook by setting the variable use_anta=true.

    This can be set for instance in your group_vars or under the task in your playbook.

    If you use_anta=false which is the default, the current version of eos_validate_state leveraging Ansible asserts will be run.

  • Ansible tags are supported for backwards compatibility until AVD version 5.0.0. To run/skip tests use --tags or --skip-tags.

    ansible-playbook playbooks/fabric-validate.yaml --tags routing_table
  • You can now run the eos_validate_state role in check_mode. This will produce a report of tests that will be performed without running the tests on your network. Tests will be marked as NOT RUN in the final reports.

    ansible-playbook playbooks/fabric-validate.yaml --check
  • You can increase the Ansible verbosity by adding multiple -v when running the playbook. This will give you visibility on which test categories are being removed from a device’s catalog by AVD according to the structured configurations.

    ansible-playbook playbooks/fabric-validate.yaml -v


ANTA mode also supports other functionnalities. For more details, please refer to the input variables below.
