Attaching NICs to a BMS¶

Function¶

This API is used to attach one or more NICs to a BMS.

URI¶

POST /v1/{project_id}/baremetalservers/{server_id}/nics

Table 1 lists the parameters.

**Table 1** Parameter description¶
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the project ID, see Obtaining a Project ID.
server_id	Yes	Specifies the BMS ID. You can obtain the BMS ID from the BMS console or by calling the Querying BMSs (Native OpenStack API).

Request¶

Request parameters

Parameter	Mandatory	Type	Description
nics	Yes	Array of objects	Specifies the NICs to be attached. For details, see Table 2. Constraints: Currently, you can concurrently attach a maximum of 10 NICs to a BMS. If more than 10 NICs are attached concurrently, the attachment may fail.

Parameter

Mandatory

Type

Description

nics

Yes

Array of objects

Specifies the NICs to be attached. For details, see Table 2.

Constraints:

Currently, you can concurrently attach a maximum of 10 NICs to a BMS. If more than 10 NICs are attached concurrently, the attachment may fail.

**Table 2** **nics** field data structure description¶
Parameter	Mandatory	Type	Description
subnet_id	Yes	String	Specifies the subnet ID of the NIC. You can obtain the subnet ID (in UUID format) from the console or by referring to in Virtual Private Cloud API Reference. Constraints: If subnet_id is specified, the value of quota:min_rate will be used as the minimum NIC bandwidth by default. If subnet_id is specified, the value of quota:vif_multiqueue_num will be used as the number of queues for a NIC by default. For details about quota:min_rate and quota:vif_multiqueue_num, see Querying Details About extra_specs Parameters of a BMS Flavor (Native OpenStack API).
security_groups	No	Array of objects	Specifies the security groups for the NIC. For details, see Table 3. Constraints: This parameter is valid only when subnet_id is specified. It is mandatory when subnet_id is used to attach NICs across tenants.
ip_address	No	String	Specifies the IP address of the NIC. If this parameter is left blank, the IP address is automatically assigned. Constraints: This parameter is valid only if subnet_id is specified.

**Table 3** **security_groups** field data structure description¶
Parameter	Mandatory	Type	Description
id	Yes	String	Specifies the security group ID.

Example request

{
    "nics": [
        {
            "subnet_id": "d32019d3-bc6e-4319-9c1d-6722fc136a23",
            "security_groups": [
                {

            ]
        }
    ]
}
