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

  • You can modify only the queue numbers of secondary ENIs.
  • You can modify the queue number of an ENI only when the ENI is in the Available state.
  • The maximum queue number of secondary ENIs cannot exceed the quota provided by the instance type of the instance to which the secondary ENIs are bound. For more information about the quota, query the TotalEniQueueQuantity parameter by calling the DescribeInstanceTypes operation.
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://.
