Port Role Screen - ZyXEL Communications UAG5100 User Manual

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

* - 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.

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.
