module: aci_bd_subnet
short_description: Manage Subnets on Cisco ACI fabrics (fv:Subnet)
description:
- Manage Subnets on Cisco ACI fabrics.
- More information from the internal APIC class
I(fv:Subnet) at U(https://developer.cisco.com/media/mim-ref/MO-fvSubnet.html).
author:
- Swetha Chunduri (@schunduri)
- Dag Wieers (@dagwieers)
- Jacob McGill (@jmcgill298)
version_added: '2.4'
requirements:
- ACI Fabric 1.0(3f)+
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.
options:
bd:
description:
- The name of the Bridge Domain.
description:
description:
- The description for the Subnet.
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 new Subnets to C(no).
choices: [ no, yes ]
default: no
gateway:
description:
- The IPv4 or IPv6 gateway address for the Subnet.
aliases: [ gateway_ip ]
mask:
description:
- The subnet mask for the Subnet.
- This is the number assocated with CIDR notation.
choices: [ Any 0 to 32 for IPv4 Addresses, 0-128 for IPv6 Addresses ]
aliases: [ subnet_mask ]
nd_prefix_policy:
description:
- The IPv6 Neighbor Discovery Prefix Policy to associate with the Subnet.
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 new Subnets to C(no).
choices: [ no, yes ]
default: no
route_profile:
description:
- The Route Profile to the associate with the Subnet.
route_profile_l3_out:
description:
- The L3 Out that contains the assocated Route Profile.
scope:
description:
- Determines if 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 APIC defaults new Subnets to C(private).
choices: [ private, public, shared ]
default: private
subnet_control:
description:
- 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 treate 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 new Subnets to C(nd_ra).
choices: [ nd_ra, no_gw, querier_ip, unspecified ]
default: nd_ra
subnet_name:
description:
- The name of the Subnet.
aliases: [ name ]
tenant:
description:
- The name of the Tenant.
aliases: [ tenant_name ]
