Appendix A: Accessing the Command-Line Interface

LAN IP Address

Enter 2 then type the IP address provided by your LAN administrator. Use the following criteria to determine if or how the LAN IP address will be changed:

•Enter an IP address for the LAN (10Base-T) port provided by the LAN administrator if you are not implementing a 10.0.0.0 subnet.

•Use the default IP address for the LAN port which is 10.0.0.1. If you choose to use the default IP address, ensure that the devices on your LAN are on the same subnet as this modem LAN port.

•If you want a DHCP server on your LAN to automatically provide the modem LAN port IP address, select Client for the DHCP configuration (configuration step is on page 104).

LAN Subnet Mask

Enter 3 then type the LAN subnet mask provided by your LAN administrator. Use the following criteria to determine if or how the LAN subnet mask will be changed:

•Enter the subnet mask for the LAN (10Base-T) port provided by the LAN administrator.

•Use the default subnet mask for the LAN port which is 255.255.255.0. If you choose to use the default subnet mask, ensure that it allows devices on your LAN to access the modem LAN port.

•If you want a DHCP server on your LAN to automatically provide the subnet mask in addition to the IP address, select Client for the DHCP configuration (configuration step is on page 104).

System Default Gateway

Enter 4 then type the IP address of the DHCP default gateway that is provided by the LAN administrator for devices on the LAN. After you configure this IP address, the modem provides this IP address as a default DHCP gateway to requesting DHCP clients (such as PCs) on the LAN. If there are no gateways on the LAN, then the modem LAN port IP address can be assigned as the gateway.

Ethernet Full Duplex

Enter 5 then select 2 for Enabled if you want to set the modem LAN port to full-duplex transmission. Select 1 for Disabled (default) if you want to set the modem LAN port to half-duplex.
