7.3 Interface Mode / Bridge Groups
In this menu, you define the operation mode for your device's interfaces.
Routing versus bridging
Bridging connects networks of the same type. In contrast to routing, bridges operate at lay-
er 2 of the OSI model (data link layer), are independent of higher-level protocols and trans-
mit data packets using MAC addresses. Data transmission is transparent, which means the
information contained in the data packets is not interpreted.
With routing, different networks are connected at layer 3 (network layer) of the OSI model
and information is routed from one network to the other.
Conventions for port/interface names
If your device has a radio port, it receives the interface name WLAN. If there are several ra-
dio modules, the names of wireless ports in the user interface of your device are made up
of the following parts:
(a) WLAN
(b) Number of the physical port (1 or 2)
Example:
8$,9
The name of the Ethernet port is made up of the following parts:
(a) ETH
(b) Number of the port
Example:
)>
The name of the interface connected to an Ethernet port is made up of the following parts:
(a) Abbreviation for interface type, whereby
stands for internet.
(b) Number of the Ethernet port
(c) Number of the interface
Example:
(first interface on the first Ethernet port)
The name of the bridge group is made up of the following parts:
(a) Abbreviation for interface type, whereby
7
stands for bridge group.
(b) Number of the bridge group
