AttachNetworkInterface

Description

The elastic network card must be in the available (Available) state.

The instance must be in Running or Stopped status.

Elastic network cards can only be attached to VPC type instances and must be in the same VPC as the instance.

An elastic network card can only be attached to one instance at the same time.

One instance can be attached to multiple elastic network cards at the same time. Please refer to Elastic Network Cards to view the number of elastic network cards that can be attached to each instance specification.

Since VPC virtual switches cannot span across availability zones, the instance to which the elastic network adapter is attached and the switch where the elastic network adapter is located must belong to the same availability zone.
