CreateNetworkInterface

Description

The newly created elastic network card is available (Available) status.

Elastic network cards only support VPC type instances attached to the same availability zone.

An elastic network card can only be attached to one instance. You need to detach it from the current instance before attaching it to a new instance.

When the elastic network card is reattached to another instance, its properties follow the elastic network card, and network traffic is also redirected to the new instance.

An account can create up to 100 elastic network cards by default in an Alibaba Cloud region. If you need more, please submit a ticket request.
