## Synopsis

- Manage Subnets on Cisco ACI fabrics.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
bd string |  | The name of the Bridge Domain. aliases: bd_name
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
description string |  | The description for the Subnet. aliases: descr

enable_vip
boolean

Choices:
- no
- yes

Determines if the Subnet should be treated as a VIP; used when the BD is extended to multiple sites.
The APIC defaults to `no` when unset during creation.

gateway string |  | The IPv4 or IPv6 gateway address for the Subnet. aliases: gateway_ip
host string / required |  | IP Address or hostname of APIC resolvable by Ansible control host. aliases: hostname
mask integer |  | The subnet mask for the Subnet. This is the number associated with CIDR notation. For IPv4 addresses, accepted values range between `0` and `32`. For IPv6 addresses, accepted Values range between `0` and `128`. aliases: subnet_mask
nd_prefix_policy string |  | The IPv6 Neighbor Discovery Prefix Policy to associate with the Subnet.

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`.

preferred
boolean

Choices:
- no
- yes

Determines if the Subnet is preferred over all available Subnets. Only one Subnet per Address Family (IPv4/IPv6). can be preferred in the Bridge Domain.
The APIC defaults to `no` when unset during creation.

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
route_profile string |  | The Route Profile to the associate with the Subnet.
route_profile_l3_out string |  | The L3 Out that contains the associated Route Profile.

scope
list

Choices:
- private
- public
- shared

Determines the scope of the Subnet.
The `private` option only allows communication with hosts in the same VRF.
The `public` option allows the Subnet to be advertised outside of the ACI Fabric, and allows communication with hosts in other VRFs.
The shared option limits communication to hosts in either the same VRF or the shared VRF.
The value is a list of options, `private` and `public` are mutually exclusive, but both can be used with `shared`.
The APIC defaults to `private` when unset during creation.

state
string

Choices:
- absent
- present ←
- query

Use `present` or `absent` for adding or removing.
Use `query` for listing an object or multiple objects.

subnet_control
string

Choices:
- nd_ra
- no_gw
- querier_ip
- unspecified

Determines the Subnet's Control State.
The `querier_ip` option is used to treat the gateway_ip as an IGMP querier source IP.
The `nd_ra` option is used to treat the gateway_ip address as a Neighbor Discovery Router Advertisement Prefix.
The `no_gw` option is used to remove default gateway functionality from the gateway address.
The APIC defaults to `nd_ra` when unset during creation.

subnet_name string |  | The name of the Subnet. aliases: name
tenant string |  | The name of the Tenant. aliases: tenant_name
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.

## Notes

Note

- The `gateway` parameter is the root key used to access the Subnet (not name), so the `gateway` is required when the state is `absent` or `present`.
- The `tenant` and `bd` used must exist before using this module in your playbook. The aci_tenant module and aci_bd can be used for these.
