Interfaces
This chapter shows you how to use interface-related commands.
13.1 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 at most one zone.
• Many interfaces 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.
13.1.1 Types of Interfaces
You can create several types of interfaces in each ZyWALL / USG model. The types supported vary
by ZyWALL / USG model.
•
Port groups
create a hardware connection between physical ports at the layer-2 (data link, MAC
address) level.
•
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 ZyWALL / USG automatically adds or
removes the tags as needed. Each VLAN can only be associated with one Ethernet interface.
•
Bridge interfaces
create a software connection between Ethernet or VLAN interfaces at the
layer-2 (data link, MAC address) level. Unlike port groups, bridge interfaces can take advantage
of some security features in the ZyWALL / USG. You can also assign an IP address and subnet
mask to the bridge.
•
PPPoE/PPTP interfaces
support Point-to-Point Protocols (PPP). ISP accounts are required for
PPPoE/PPTP interfaces.
•
Cellular interfaces
are for 3G WAN connections via a connected 3G device.
•
•
Virtual interfaces
(IP alias) provide additional routing information in the ZyWALL / USG. There
are three types:
virtual Ethernet interfaces
,
virtual VLAN interfaces
, and
virtual bridge
interfaces
.
•
Trunks
manage load balancing between interfaces.
