Gateway/bridge management interface. This interface is used as a
bridge host interface or gateway interface depending on the
operation mode. In this manual it is called VBRIDGE. On the
MW1122 web pages, the interface is called gateway or bridge IP
interface.
MW1122 can operate in four different main modes:
D
Bridging only
D
Routing/tunneling IP only
D
Routing/tunneling IP, bridging all but IP
D
Routing/tunneling IP and bridging all, including IP
The mode in which MW1122 operates depends on the configuration of
the unit’s interfaces.
LAN and WLAN interfaces
LAN and WLAN interfaces can be configured individually to bridge
and route packets. There are three different operational modes in both
LAN and WLAN interfaces:
D
Bridging only; only bridging is activated in the interface. In this
case the interface bridges all protocols.
D
Routing only; only IP address is configured in the interface. In this
case, the interface routes IP packets.
D
Bridging and routing; Bridging is activated in the interface and IP
address is configured in the interface. In this case, the interface
routes IP packets and bridges all other packets.
Slaved WLAN operation
The wireless LAN interface can be configured to operate as a slave to
the Ethernet interface. In this case, there is no need to configure the IP
address or bridging to the wireless LAN interface. The Ethernet and
the wireless LAN interface are bridged together internally and both
interfaces are treated as a single LAN interface. All LAN
configuration parameters defining bridging and IP-related parameters,
such as IP address, admin-disabled and RIP configuration address, are
used for both LAN and WLAN interfaces.
Internal host/gateway interface
There is a special host/gateway logical IP interface within MW1122
called VBRIDGE. This interface has a specific purpose in MW1122.
In applications where some ATM virtual channel connections are used
for bridging IP traffic and some other ATM virtual channel
