## Synopsis

- Manages Bridge Domains (BD) on Cisco ACI fabrics.

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
arp_flooding boolean | Choices: no yes | Determines if the Bridge Domain should flood ARP traffic. The APIC defaults to `no` when unset during creation.
bd string |  | The name of the Bridge Domain. aliases: bd_name, name
bd_type string | Choices: ethernet 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. 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 |  | Description for the Bridge Domain.
enable_multicast boolean | Choices: no yes | Determines if PIM is enabled. The APIC defaults to `no` when unset during creation.
enable_routing boolean | Choices: no yes | Determines if IP forwarding should be allowed. The APIC defaults to `yes` when unset during creation.
endpoint_clear boolean | Choices: no yes | Clears all End Points in all Leaves when `yes`. The value is not reset to disabled once End Points have been cleared; that requires a second task. The APIC defaults to `no` when unset during creation.
endpoint_move_detect string | Choices: default garp | Determines if GARP should be enabled to detect when End Points move. The APIC defaults to `garp` when unset during creation.
endpoint_retention_action string | Choices: inherit resolve | Determines if the Bridge Domain should inherit or resolve the End Point Retention Policy. The APIC defaults to `resolve` when unset during creation.
endpoint_retention_policy string |  | The name of the End Point Retention Policy the Bridge Domain should use when overriding the default End Point Retention Policy.
host string / required |  | IP Address or hostname of APIC resolvable by Ansible control host. aliases: hostname
igmp_snoop_policy string |  | The name of the IGMP Snooping Policy the Bridge Domain should use when overriding the default IGMP Snooping Policy.
ip_learning boolean | Choices: no yes | Determines if the Bridge Domain should learn End Point IPs. The APIC defaults to `yes` when unset during creation.
ipv6_nd_policy string |  | The name of the IPv6 Neighbor Discovery Policy the Bridge Domain should use when overridding the default IPV6 ND Policy.
l2_unknown_unicast string | Choices: proxy flood | Determines what forwarding method to use for unknown l2 destinations. The APIC defaults to `proxy` when unset during creation.
l3_unknown_multicast string | Choices: flood opt-flood | Determines the forwarding method to use for unknown multicast destinations. The APIC defaults to `flood` when unset during creation.
limit_ip_learn boolean | Choices: no yes | Determines if the BD should limit IP learning to only subnets owned by the Bridge Domain. The APIC defaults to `yes` when unset during creation.
mac_address string added in 2.5 |  | The MAC Address to assign to the `bd` instead of using the default. The APIC defaults to `00:22:BD:F8:19:FF` when unset during creation. aliases: mac
multi_dest string | Choices: bd-flood drop encap-flood | Determines the forwarding method for L2 multicast, broadcast, and link layer traffic. The APIC defaults to `bd-flood` when unset during creation.
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
state string | Choices: absent present ← query | Use `present` or `absent` for adding or removing. Use `query` for listing an object or multiple objects.
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.
vrf string |  | The name of the VRF. aliases: vrf_name

## Notes

Note

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