Chapter 8 Interfaces 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 UAG, 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. Table 39 Relationships Between Different Types of Interfaces INTERFACE port group Ethernet interface REQUIRED PORT / INTERFACE physical port physical port VLAN interface bridge interface port group Ethernet interface Ethernet interface* PPP interface VLAN interface* Ethernet interface* VLAN interface* bridge interface virtual interface WAN1, WAN2 (virtual Ethernet interface) Ethernet interface* (virtual VLAN interface) VLAN interface* (virtual bridge interface) trunk bridge interface Ethernet interface VLAN interface bridge interface PPP interface * - You cannot set up a PPP interface, virtual Ethernet interface or virtual VLAN interface if the underlying interface is a member of a bridge. You also cannot add an Ethernet interface or VLAN interface to a bridge if the member interface has a virtual interface or PPP interface on top of it.
