Table 46 Ethernet, Vlan, Bridge, Ppp, And Virtual Interfaces Characteristics; Table 47 Relationships Between Different Types Of Interfaces - ZyXEL Communications 200 Series User Manual

Trunks and the auxiliary interface have many characteristics that are specific to each type of
interface. See
types of interfaces--Ethernet, VLAN, bridge, PPPoE/PPTP, and virtual--have a lot of similar
characteristics. These characteristics are listed in the following table and discussed in more
detail below.

* - Each name consists of 2-4 letters (interface type), followed by a number (x). For most interfaces, x is limited
by the maximum number of the type of interface. For VLAN interfaces, x is defined by the number you
enter in the VLAN name field. For example, Ethernet interface names are wan1, wan2, opt, lan1, ext-
wlan, dmz; 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 wan1 are called wan1:1, wan1:2, 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.
Relationships Between Interfaces
In the ZyWALL, interfaces are usually created on top of other interfaces. Only Ethernet
interfaces are created directly on top of the physical ports or port groups (multiple ports using
the same port role). The relationships between interfaces are explained in the following table.
