This chapter shows you how to use interface-related commands.
6.1 Interface Overview
In general, an interface has the following characteristics.
• An interface is a logical entity through which (layer-3) packets pass.
• An interface is bound to a physical port or another interface.
• Many interfaces can share the same physical port.
• An interface is bound to one zone at most.
• Many interface can belong to the same zone.
• Layer-3 virtualization (IP alias, for example) is a kind of interface.
Some characteristics do not apply to some types of interfaces.
6.1.1 Types of Interfaces
You can create several types of interfaces in the NXC:
• Ethernet interfaces are the foundation for defining other interfaces and network policies.
RIP and OSPF are also configured in these interfaces.
• VLAN interfaces receive and send tagged frames. The NXC automatically adds or
removes the tags as needed.
6.2 Interface General Commands Summary
The following table identifies the values required for many of these commands. Other input
values are discussed with the corresponding commands.
