Chapter 6 Interfaces

ZyWALL (ZLD) CLI Reference Guide

• Virtual interfaces (IP alias) provide additional routing information in the ZyWALL.

There are three types: virtual Ethernet interfaces, virtual VLAN interfaces, and virtual

bridge interfaces.

•The auxiliary interface, along with an external modem, provides an interface the

ZyWALL can use to dial out. This interface can be used as a backup WAN interface, for

example. The auxiliary interface controls the DIAL BACKUP port (labeled AUX on

some models).

• Trunks manage load balancing between interfaces.

Port groups, trunks, and the auxiliary interface have a lot of characteristics that are specific to

each type of interface. These characteristics are listed in the following tables and discussed in

more detail farther on.

* - The format of interface names is strict. Each name consists of 2-4 letters (interface type), followed by a

number (x, limited by the maximum number of each type of interface). For example, Ethernet interface

names are ge1, ge2, ge3, ...; VLAN interfaces are vlan0, vlan1, vlan2, ...; and so on.

** - The names of virtual interfaces are derived from the interfaces on which they are created. For example,

virtual interfaces created on Ethernet interface ge1 are called ge1:1, ge1:2, and so on. Virtual interfaces

created on VLAN interface vlan2 are called vlan2:1, vlan2:2, and so on. You cannot specify the number

after the colon(:) in the web configurator; it is a sequential number. You can specify the number after the

colon if you use the CLI to set up a virtual Interface Parameters
