DGateway/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:
DBridging only
DRouting/tunneling IP only
DRouting/tunneling IP, bridging all but IP
DRouting/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:
DBridging only; only bridging is activated in the interface. In this case the interface bridges all protocols.
DRouting only; only IP address is configured in the interface. In this case, the interface routes IP packets.
DBridging 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
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
