module: aci_bd_subnet
short_description: Manage Subnets (fv:Subnet)
description:
- Manage Subnets on Cisco ACI fabrics.
version_added: '2.4'
options:
bd:
description:
- The name of the Bridge Domain.
type: str
aliases: [ bd_name ]
description:
description:
- The description for the Subnet.
type: str
aliases: [ descr ]
enable_vip:
description:
- Determines if the Subnet should be treated as a VIP; used when the BD is extended to multiple sites.
- The APIC defaults to C(no) when unset during creation.
type: bool
gateway:
description:
- The IPv4 or IPv6 gateway address for the Subnet.
type: str
aliases: [ gateway_ip ]
mask:
description:
- The subnet mask for the Subnet.
- This is the number associated with CIDR notation.
- For IPv4 addresses, accepted values range between C(0) and C(32).
- For IPv6 addresses, accepted Values range between C(0) and C(128).
type: int
aliases: [ subnet_mask ]
nd_prefix_policy:
description:
- The IPv6 Neighbor Discovery Prefix Policy to associate with the Subnet.
type: str
preferred:
description:
- 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 C(no) when unset during creation.
type: bool
route_profile:
description:
- The Route Profile to the associate with the Subnet.
type: str
route_profile_l3_out:
description:
- The L3 Out that contains the associated Route Profile.
type: str
scope:
description:
- Determines the scope of the Subnet.
- The C(private) option only allows communication with hosts in the same VRF.
- The C(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, C(private) and C(public) are mutually exclusive, but both can be used with C(shared).
- The APIC defaults to C(private) when unset during creation.
type: list
choices:
- private
- public
- shared
subnet_control:
description:
- Determines the Subnet's Control State.
- The C(querier_ip) option is used to treat the gateway_ip as an IGMP querier source IP.
- The C(nd_ra) option is used to treat the gateway_ip address as a Neighbor Discovery Router Advertisement Prefix.
- The C(no_gw) option is used to remove default gateway functionality from the gateway address.
- The APIC defaults to C(nd_ra) when unset during creation.
type: str
choices: [ nd_ra, no_gw, querier_ip, unspecified ]
subnet_name:
description:
- The name of the Subnet.
type: str
aliases: [ name ]
tenant:
description:
- The name of the Tenant.
type: str
aliases: [ tenant_name ]
state:
description:
- Use C(present) or C(absent) for adding or removing.
- Use C(query) for listing an object or multiple objects.
type: str
choices: [ absent, present, query ]
default: present
extends_documentation_fragment: aci
notes:
- The C(gateway) parameter is the root key used to access the Subnet (not name), so the C(gateway)
is required when the state is C(absent) or C(present).
- The C(tenant) and C(bd) used must exist before using this module in your playbook.
The M(aci_tenant) module and M(aci_bd) can be used for these.
