Updating the Port IP Address

Function

This API is used to update the port IP address.

Restrictions

The port must be a primary network port and cannot contain IPv6 addresses.
The port cannot be bound to a virtual IP address.
The subnet of the port after the update and the current subnet must belong to the same VPC.
The ECS corresponding to the port is stopped.

URI

PUT /v1/{project_id}/ports/{port_id}/subnet-ip

Table 1 describes the parameters.

**Table 1** Parameter description
Name	Mandatory	Description
port_id	Yes	Specifies the port ID, which uniquely identifies the port.
project_id	Yes	Specifies the project ID. For details about how to obtain a project ID, see Obtaining a Project ID.

Request Message

Request parameter

**Table 2** Request parameter
Name	Mandatory	Type	Description
subnet_id	Yes	String	Specifies the subnet ID.
ip_address	No	String	Specifies the port IP address. The IP address must be in the subnet CIDR block.

Example request

PUT https://{Endpoint}/v1/{project_id}/ports/7204e0da-40de-4207-a536-6f59b84f6f0e/subnet-ip

{
    "subnet_id": "689156ca-038f-4478-b265-fd26aa8bbe31",
    "ip_address": "192.168.0.9"
}

Response Message

Response parameter

**Table 3** Response parameter
Name	Type	Description
port	Object	Specifies the port objects. For details, see Table 4.

**Table 4** Description of the **port** field
Name	Type	Description
id	String	Specifies the port ID, which uniquely identifies the port.
name	String	Specifies the port name. The value can contain no more than 255 characters. This parameter is left blank by default.
network_id	String	Specifies the ID of the network to which the port belongs. The network ID must be a real one in the network environment.
admin_state_up	Boolean	Specifies the administrative state of the port. The value can only be true, and the default value is true.
mac_address	String	Specifies the port MAC address. The system automatically sets this parameter, and you are not allowed to configure the parameter value.
fixed_ips	Array of fixed_ip objects	Specifies the port IP address. For details, see Table 5. A port supports only one fixed IP address that cannot be changed.
device_id	String	Specifies the ID of the device to which the port belongs. The system automatically sets this parameter, and you are not allowed to configure or change the parameter value.
device_owner	String	Specifies the belonged device, which can be the DHCP server, router, load balancer, or Nova. The system automatically sets this parameter, and you are not allowed to configure or change the parameter value.
tenant_id	String	Specifies the project ID.
status	String	The value can be ACTIVE, BUILD, or DOWN. Specifies the port status. The status of a HANA SR-IOV VM port is always DOWN.
security_groups	Array of strings	Specifies the security group UUID (extended attribute).
allowed_address_pairs	Array of allow_address_pair objects	Specifies a set of zero or more allowed address pairs. An address pair consists of an IP address and MAC address. This attribute is extended. For details, see parameter allow_address_pair in Table 6. The IP address cannot be 0.0.0.0. Configure an independent security group for the port if a large CIDR block (subnet mask less than 24) is configured for parameter allowed_address_pairs.
extra_dhcp_opts	Array of extra_dhcp_opt objects	Specifies the extended option (extended attribute) of DHCP. For details, see Table 7.
binding:vnic_type	String	Specifies the type of the bound vNIC. The value can be normal or direct. Parameter normal indicates software switching. Parameter direct indicates SR-IOV PCIe passthrough, which is not supported.

**Table 5** **fixed_ip** object
Name	Type	Description
subnet_id	String	Specifies the ID of the subnet to which the port belongs.
ip_address	String	Specifies the port IP address.

**Table 6** **allow_address_pair** object
Name	Type	Description
ip_address	String	Specifies the IP address. You cannot set it to 0.0.0.0. Configure an independent security group for the port if a large CIDR block (subnet mask less than 24) is configured for parameter allowed_address_pairs.
mac_address	String	Specifies the MAC address.

**Table 7** **extra_dhcp_opt** object
Name	Type	Description
opt_name	String	Specifies the option name.
opt_value	String	Specifies the option value.
