Container Instance Interfaces

To provide flexible physical interface use for container instances, you can create VLAN subinterfaces in FXOS and also share interfaces (VLAN or physical) between multiple instances. Native instances cannot use VLAN subinterfaces or shared interfaces. A multi-instance cluster cannot use VLAN subinterfaces or shared interfaces. An exception is made for the cluster control link, which can use a subinterface of the Cluster EtherChannel. See Shared Interface Scalability and Add a VLAN Subinterface for Container Instances.

Note	This document discusses FXOS VLAN subinterfaces only. You can separately create subinterfaces within the threat defense application. See FXOS Interfaces vs. Application Interfaces for more information.
