Independent Interface States in the Chassis and in the Instance
You can administratively enable and disable interfaces in both the chassis and in the instance. For an interface
to be operational, the interface must be enabled in both locations. Because the interface state is controlled
independently, you may have a mismatch between the chassis and instance.
The default state of an interface within the instance depends on the type of interface. For example, the physical
interface or EtherChannel is disabled by default within the instance, but a subinterface is enabled by default.
