## Synopsis

- Provides rollback and rollback preview functionality for Cisco ACI fabrics.
- Config Rollbacks are done using snapshots `aci_snapshot` with the configImportP class.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
certificate_name string |  | The X.509 certificate name attached to the APIC AAA user used for signature-based authentication. If a `private_key` filename was provided, this defaults to the `private_key` basename, without extension. If PEM-formatted content was provided for `private_key`, this defaults to the `username` value. aliases: cert_name
compare_export_policy string |  | The export policy that the `compare_snapshot` is associated to.
compare_snapshot string |  | The name of the snapshot to compare with `snapshot`.
description string |  | The description for the Import Policy. aliases: descr
export_policy string / required |  | The export policy that the `snapshot` is associated to.
fail_on_decrypt boolean | Choices: no yes | Determines if the APIC should fail the rollback if unable to decrypt secured data. The APIC defaults to `yes` when unset.
host string / required |  | IP Address or hostname of APIC resolvable by Ansible control host. aliases: hostname
import_mode string | Choices: atomic best-effort | Determines how the import should be handled by the APIC. The APIC defaults to `atomic` when unset.
import_policy string |  | The name of the Import Policy to use for config rollback.
import_type string | Choices: merge replace | Determines how the current and snapshot configuration should be compared for replacement. The APIC defaults to `replace` when unset.
output_level string | Choices: debug info normal ← | Influence the output of this ACI module. `normal` means the standard output, incl. `current` dict `info` adds informational output, incl. `previous`, `proposed` and `sent` dicts `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. This value also influences the default `certificate_name` that is used. This option is mutual exclusive with `password`. If `password` is provided too, it will be ignored. aliases: cert_key
snapshot string / required |  | The name of the snapshot to rollback to, or the base snapshot to use for comparison. The `aci_snapshot` module can be used to query the list of available snapshots.
state string | Choices: preview rollback ← | Use `preview` for previewing the diff between two snapshots. Use `rollback` for reverting the configuration to a previous snapshot.
timeout integer | Default: 30 | The socket level timeout in seconds.
use_proxy boolean | Choices: no yes ← | If `no`, it will not use a proxy, even if one is defined in an environment variable on the target hosts.
use_ssl boolean | Choices: no yes ← | If `no`, an HTTP connection will be used instead of the default HTTPS connection.
username string | Default: "admin" | The username to use for authentication. aliases: user
validate_certs boolean | Choices: no yes ← | If `no`, SSL certificates will not be validated. This should only set to `no` when used on personally controlled sites using self-signed certificates.
