pyATS DNAC REST testbed formatting

omz — Tue, 24 Mar 2020 13:00:06 GMT

Following this blog post -

https://blogs.cisco.com/developer/dna-center-pyats-genie

with testbed file -

devices:
    sandboxdnac2:
        alias: dnac
        type: dnac
        os: dnac
        credentials:
            rest:
                username: devnetuser
                password: "Cisco123!"
        connections:
            rest:
                class: rest.connector.Rest
                host: sandboxdnac2.cisco.com
                verify: False

I get key error for ‘ip’

$ genie dnac interface isis ospf --testbed-file dna.yaml --output initial --via dnac:rest --device:dnac -v

KeyError: 'ip'


'ip'

If I replace the host: in testbed dna.yaml with ip: the key error is resolved.

But the credentials are not being read from the testbed file. I have tried placing credentials at different places within the file and can validate the file with pyats validate.

testbed:

name: myTestbed

credentials:

default:

username: devnetuser

password: "Cisco123!"

devices:

dnac:

alias: dnac

type: dnac

os: dnac

credentials:

rest:

username: devnetuser

password: "Cisco123!"

custom:

abstraction:

order: [os]

connections:

rest:

# Rest connector class

Can you please advise on how to properly format the testbed file?

I have tried to create the testbed file with create tool but it doesn’t work for rest connection .. defaults to cli.

Thank you
