- fc

The type of traffic on the Bridge Domain.
The APIC defaults to `ethernet` when unset during creation.

certificate_name string |  | The X.509 certificate name attached to the APIC AAA user used for signature-based authentication.

endpoint_clear
boolean

`debug` adds debugging output, incl. `filter_string`, `method`, `response`, `status` and `url` information

password string / required |  | The password to use for authentication. This option is mutual exclusive with `private_key`. If `private_key` is provided too, it will be used instead.
port integer |  | Port number to be used for REST connection. The default value depends on parameter `use_ssl`.
private_key string / required |  | Either a PEM-formatted private key file or the private key content used for signature-based authentication.

state
string

Choices:

- query

Use `present` or `absent` for adding or removing.

## Notes

Note

- The `tenant` used must exist before using this module in your playbook. The aci_tenant module can be used for this.
