You can call this operation to modify the properties such as the name, description, and security group of an elastic network interface (ENI).

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes ModifyNetworkInterfaceAttribute

The operation that you want to perform. Set the value to ModifyNetworkInterfaceAttribute.
NetworkInterfaceId String Yes eni-bp67acfmxazb4p****

The ID of the ENI.
RegionId String Yes cn-hangzhou

The region ID of the ENI. You can call the DescribeRegions operation to query the most recent region list.

SecurityGroupId.N RepeatList No sg-bp67acfmxazb4p****

The ID of security group N to which the ENI finally belongs. If a security group to which the ENI has belonged is in the ID list, that security group is removed from the list. Valid values of N: 1, 2, 3, 4, and 5.

Note After you modify the security group, the modification will take effect after a short delay.
NetworkInterfaceName String No eniTestName

The name of the ENI. The name must be 2 to 128 characters in length. It must start with a letter and cannot start with http:// or https://. It can contain letters, digits, colons (:), underscores (_), and hyphens (-).

This parameter is empty by default.
QueueNumber Integer No 8

The number of ENI queues. Valid values: 1 to 2048.

  • You can modify only the queue numbers of secondary ENIs.
  • You can modify the queue number of a secondary ENI only when the ENI is in the Available state or the secondary ENI is bound (InUse) to an instance that is in the Stopped state.
  • The maximum queue number of a single secondary ENI cannot exceed the service quota of queues allowed by the instance type of the instance to which the secondary ENI is bound. The total queue number of all ENIs that are bound to the instance also cannot exceed the total queue quota allowed by the instance type of the instance. To learn the queue quotas for a single ENI and all ENIs bound to an instance, you can call the DescribeInstanceTypes operation to query the MaximumQueueNumberPerEni and TotalEniQueueQuantity fields.
Description String No testDescription

The description of the ENI. The description must be 2 to 256 characters in length and cannot start with http:// or https://.

This parameter is empty by default.
