Chapter 10 Interfaces 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 65 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. Finding Out More • See Section 10.8 on page 191 for background information on interfaces. • See Chapter 11 on page 195 to configure load balancing using trunks. 10.2 Port Role Screen To access this screen, click Configuration > Network > Interface > Port Role. Use the Port Role screen to set the UAG's flexible ports as part of the lan1, lan2 or dmz interfaces. This creates a hardware connection between the physical ports at the layer-2 (data link, MAC address) level. This provides wire-speed throughput but no security. UAG Series User's Guide 156
