Modifies the attributes of an elastic network interface (ENI), such as its name, description, and security group.

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.

RegionId String Yes cn-hangzhou

The region ID of the ENI. You can call the DescribeRegions operation to query thecurrent list of regions.

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.

NetworkInterfaceId String Yes eni-bp67acfmxazb4p****

The ID of the ENI.

QueueNumber Integer No 8

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

  • You can modify the number of queues supported only by the secondary ENI.
  • You can modify the number of queues supported by the 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 number of queues supported by the secondary ENI cannot exceed the maximum number of queues that the instance allows for each ENI. The total number of queues for all ENIs on the instance cannot exceed the queue quota that the instance allows. To obtain information about the maximum number of queues per ENI and the queue quota for an instance type, you can call the DescribeInstanceTypes operation to query the MaximumQueueNumberPerEni and TotalEniQueueQuantity values.
Description String No testDescription

The description of the ENI. The description must be 2 to 255 characters in length and cannot start with http:// or https://.

This parameter is empty by default.

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

The list of security group IDs. Valid values of N: 1, 2, 3, 4, and 5.

  • You can modify only the security groups to which the secondary ENI is added.
  • After you specify a security group, the secondary ENI is added to the specified security group and removed from the existing security group.
Note After you modify the security group, the modification takes effect after a short delay.
