# Getting Started
This section shows how to use ANTA with basic configuration. All examples are based on Arista Test Drive (ATD) topology you can access by reaching out to your preferred SE.
## Installation
The easiest way to intall ANTA package is to run Python (`>=3.8`) and its pip package to install:
```bash
pip install anta
```
For more details about how to install package, please see the [requirements and intallation](./requirements-and-installation.md) section.
## Configure Arista EOS devices
For ANTA to be able to connect to your target devices, you need to configure your management interface
```eos
vrf instance MGMT
!
interface Management0
description oob_management
vrf MGMT
ip address 192.168.0.10/24
!
```
Then, configure access to eAPI:
```eos
!
management api http-commands
protocol https port 443
no shutdown
vrf MGMT
no shutdown
!
!
```
## Create your inventory
ANTA uses an inventory to list the target devices for the tests. You can create a file manually with this format:
```yaml
anta_inventory:
hosts:
- host: 192.168.0.10
name: spine01
tags: ['fabric', 'spine']
- host: 192.168.0.11
name: spine02
tags: ['fabric', 'spine']
- host: 192.168.0.12
name: leaf01
tags: ['fabric', 'leaf']
- host: 192.168.0.13
name: leaf02
tags: ['fabric', 'leaf']
- host: 192.168.0.14
name: leaf03
tags: ['fabric', 'leaf']
- host: 192.168.0.15
name: leaf04
tags: ['fabric', 'leaf']
```
> You can read more details about how to build your inventory [here](usage-inventory-catalog.md#create-an-inventory-file)
## Test Catalog
To test your network, ANTA relies on a test catalog to list all the tests to run against your inventory. A test catalog references python functions into a yaml file.
The structure to follow is like:
```yaml
<anta_tests_submodule>:
- <anta_tests_submodule function name>:
<test function option>:
<test function option value>
```
> You can read more details about how to build your catalog [here](usage-inventory-catalog.md#test-catalog)
Here is an example for basic tests:
```yaml
# Load anta.tests.software
anta.tests.software:
- VerifyEOSVersion: # Verifies the device is running one of the allowed EOS version.
versions: # List of allowed EOS versions.
- 4.25.4M
- 4.26.1F
- '4.28.3M-28837868.4283M (engineering build)'
- VerifyTerminAttrVersion:
versions:
- v1.22.1
anta.tests.system:
- VerifyUptime: # Verifies the device uptime is higher than a value.
minimum: 1
- VerifyNTP:
- VerifySyslog:
anta.tests.mlag:
- VerifyMlagStatus:
- VerifyMlagInterfaces:
- VerifyMlagConfigSanity:
anta.tests.configuration:
- VerifyZeroTouch: # Verifies ZeroTouch is disabled.
- VerifyRunningConfigDiffs:
```
## Test your network
ANTA comes with a generic CLI entrypoint to run tests in your network. It requires an inventory file as well as a test catalog.
This entrypoint has multiple options to manage test coverage and reporting.
```bash
# Generic ANTA options
$ anta
--8<-- "anta_help.txt"
```
```bash
# NRFU part of ANTA
Usage: anta nrfu [OPTIONS] COMMAND [ARGS]...
Run ANTA tests on devices
Options:
-u, --username TEXT Username to connect to EOS [env var: ANTA_USERNAME;
required]
-p, --password TEXT Password to connect to EOS that must be provided. It
can be prompted using '--prompt' option. [env var:
ANTA_PASSWORD]
--enable-password TEXT Password to access EOS Privileged EXEC mode. It can
be prompted using '--prompt' option. Requires '--
enable' option. [env var: ANTA_ENABLE_PASSWORD]
--enable Some commands may require EOS Privileged EXEC mode.
This option tries to access this mode before sending
a command to the device. [env var: ANTA_ENABLE]
-P, --prompt Prompt for passwords if they are not provided. [env
var: ANTA_PROMPT]
--timeout INTEGER Global connection timeout [env var: ANTA_TIMEOUT;
default: 30]
--insecure Disable SSH Host Key validation [env var:
ANTA_INSECURE]
--disable-cache Disable cache globally [env var:
ANTA_DISABLE_CACHE]
-i, --inventory FILE Path to the inventory YAML file [env var:
ANTA_INVENTORY; required]
-t, --tags TEXT List of tags using comma as separator:
tag1,tag2,tag3 [env var: ANTA_TAGS]
-c, --catalog FILE Path to the test catalog YAML file [env var:
ANTA_CATALOG; required]
--ignore-status Always exit with success [env var:
ANTA_NRFU_IGNORE_STATUS]
--ignore-error Only report failures and not errors [env var:
ANTA_NRFU_IGNORE_ERROR]
--help Show this message and exit.
Commands:
json ANTA command to check network state with JSON result
table ANTA command to check network states with table result
text ANTA command to check network states with text result
tpl-report ANTA command to check network state with templated report
```
To run the NRFU, you need to select an output format amongst ["json", "table", "text", "tpl-report"]. For a first usage, `table` is recommended. By default all test results for all devices are rendered but it can be changed to a report per test case or per host
### Default report using table
```bash
anta nrfu \
--username tom \
--password arista123 \
--enable \
--enable-password t \
--inventory .personal/inventory_atd.yml \
--catalog .personal/tests-bases.yml \
table --tags leaf
