5.3.2. Ethernet

NB3700 routers ship with an Ethernet switch (ETH1-ETH5) which can be linked via
M12 connectors.
ETH1 usually forms the LAN1 interface which should be used for LAN purposes. Other
interfaces can be used to connect other LAN segments or for configuring a WAN link.
The LAN10 interface will be available as soon as a pre-configured USB Ethernet device
has been plugged in.
Ethernet Port Assignment
Figure 5.6.: Ethernet Ports
This menu can be used to individually assign each Ethernet port to a LAN interface, just
in case you want to have different subnets per port or use one port as WAN interface. You
may assign multiple ports to the same interface. Please note that on systems without
an Ethernet switch, the ports will be bridged by software then and operated by running
the Spanning Tree Protocol (STP).
