Table 44 Ethernet, Vlan, Bridge, Pppoe/Pptp, And Virtual Interfaces Characteristics; Table 45 Relationships Between Different Types Of Interfaces - ZyXEL Communications ZyWALL USG 300 User Manual

Port groups, trunks, and the auxiliary interface have a lot of characteristics that are specific to
each type of interface. See
10.15 on page 237
PPTP, and virtual--have a lot of similar characteristics. These characteristics are listed in the
following table and discussed in more detail below.

* - 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.
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. The relationships
between interfaces are explained in the following table.
