Chapter 9 Interfaces Table 95 Ethernet, PPP, Cellular, VLAN, Bridge, and Virtual Interface Characteristics (continued) CHARACTERISTICS ETHERNET ETHERNET PPP CELLULAR VLAN BRIDGE VIRTUAL Bandwidth Yes Yes Yes Yes restrictions Yes Yes Yes Packet size Yes Yes Yes Yes (MTU) Yes Yes No DHCP DHCP server No Yes No No Yes Yes No DHCP relay No Yes No No Yes Yes No Connectivity Check Yes No Yes Yes Yes Yes No Note: - * The format of interface names other than the Ethernet and ppp interface names is strict. 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, lan1, lan2, 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 Zyxel Device, 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.
