Chapter 6: Configuring the Ports
2Enter the bridging configuration parameters:
‹Select Bridging Enable to forward Ethernet data based on MAC addresses. Click Spanning Tree Enable to enable the Spanning Tree protocol.
The Spanning Tree protocol eliminates loops in a bridged LAN topology. When Spanning Tree is selected, it becomes active when bridging is enabled. If the modem is configured for routing only, Spanning Tree does not run. See “Spanning Tree Protocol” on page 69 for more information.
3Enter the routing configuration parameters:
ŒSelect Routing Enable to forward IP datagrams based on IP addresses. See “Routing” on page 71 for more information.
Click Static Route Table to get a dialog to set up static routes. The modem can accept up to 32 static route entries. Go to “Defining Static Route Entries” on page 51 to configure these parameters.
4Enter the LAN and WAN port configuration parameters:
•Enter the LAN IP Address for the modem Ethernet
Enter the WAN IP Address for the ADSL (WAN) port. This option is available only if routing is enabled and you must enter a valid IP address. When routing is not enabled, the field is blank.
ŽEnter the LAN IP Net Mask (subnet IP mask) for the modem Ethernet
Enter the WAN IP Net Mask (subnet IP mask) for the ADSL (WAN) port. This option is available only if routing is enabled and you must enter a valid subnet mask. When routing is not enabled, the field is blank.
•The LAN Bridge Port Priority is preset to 100. Bridge Port Priority is used when Bridging mode and Spanning Tree are both enabled and determines which modem port has higher priority when active simultaneously.
The WAN Bridge Port Priority is preset to 101. Bridge Port Priority is used when Bridging mode and Spanning Tree are both enabled and determines which modem port has higher priority when active simultaneously.
