ipv6_vip_virsubnet_id

No

String

Specifies the ID of the IPv6 subnet where the load balancer resides. You can query parameter id in the response by calling the API (GET https://{VPC_Endpoint}/v1/{project_id}/subnets).

The IPv6 subnet can be updated using ipv6_vip_virsubnet_id, and the private IPv6 address of the load balancer will be changed accordingly.

Note:

  • This parameter will be passed only when IPv6 is enabled for the subnet. The subnet specified by ipv6_vip_virsubnet_id must be in the VPC specified by vpc_id.

  • This parameter can be updated only when guaranteed is set to true.

  • The value will become null if the IPv6 address is unbound from the load balancer.

  • The IPv4 subnet will not change, if IPv6 subet is updated. This parameter is unsupported. Please do not use it.

vip_subnet_cidr_id

No

String

Specifies the ID of the IPv4 subnet where the load balancer resides. You can query parameter neutron_subnet_id in the response by calling the API (GET https://{VPC_Endpoint}/v1/{project_id}/subnets).

  • The IPv4 subnet can be updated using vip_subnet_cidr_id, and the private IPv4 address of the load balancer will be changed accordingly. Note:

  • If vip_address is also specified, the IP address specified by vip_address must be in the subnet specified by vip_subnet_cidr_id and will be used as the private IPv4 address of the load balancer.

  • The IPv4 subnet must be in the VPC where the load balancer resides.

Minimum: 1

Maximum: 36

l4_flavor_id

No

String

Specifies the ID of a flavor at Layer 4.

Note:

  • This parameter can be updated only when guaranteed is set to true.

  • The value cannot be changed from null to a specific value, or in the other way around.

Minimum: 1

Maximum: 255

l7_flavor_id

No

String

Specifies the ID of a flavor at Layer 7.

Note:

  • This parameter can be updated only when guaranteed is set to true.

  • The value cannot be changed from null to a specific value, or in the other way around.

Minimum: 1

Maximum: 36

ipv6_bandwidth

No

BandwidthRef object

Specifies the ID of the bandwidth used by an IPv6 address. This parameter is available only when you create or update a load balancer with a public IPv6 address. If you use a new IPv6 address and specify a shared bandwidth, the IPv6 address will be added to the shared bandwidth.

ip_target_enable

No

Boolean

Specifies whether to enable IP as a Backend Server.

If you enable this function, you can add servers in a peer VPC connected through a VPC peering connection, or in an on-premises data center at the other end of a Direct Connect or VPN connection, by using their IP addresses.

This function is supported only by dedicated load balancers.

The value can be true (enable IP as a Backend Server) or false (disable IP as a Backend Server).

The value can only be update to true.

This parameter is not available in eu-nl region. Please do not use it.

elb_virsubnet_ids

No

Array of strings

Specifies the IDs of subnets on the downstream plane. You can query parameter neutron_network_id in the response by calling the API (GET https://{VPC_Endpoint}/v1/{project_id}/subnets).

  • If the IDs of the subnets required by the load balancer are specified in elb_virsubnet_ids, the subnets will still be bound to the load balancer.

  • If the IDs of the subnets required by the load balancer are not specified in elb_virsubnet_ids, the subnets will be unbound from the load balancers. Do not unbound the subnets that have been used by the load balancer. Otherwise, an error will be returned.

  • If the IDs of the subnets are specified in elb_virsubnet_ids, but not on the downstream plane, a new load balancer will be bound to the downstream plane.

Note:

  • All subnets belong to the same VPC where the load balancer resides.

  • Edge subnets are not supported.

Minimum: 1

Maximum: 64

deletion_protection_enable
