Configuring the LAN Port
Note Configure the LAN parameters before connecting the node to a LAN.
Note Refer to the Cisco WAN Switching Command Reference for additional information.
Step 1 Contact a system administrator to obtain IP addresses for the workstation and for the IGX node.
Step 2 Normally, the system administrator updates the network information server (NIS) database, as
applicable (if a NIS is used), and adds the IP addresses for the workstation and node to the NIS database.
• The addresses shown are examples. Use the addresses obtained from the system administrator. (This
example is for a workstation named “hedgehog” at address 192.187.207.200. It also assumes that
the IGX node LAN port for node “sanfran” has been assigned an IP address of 192.187.210.30 and
a hostname of “sanfran.”)
192.187.207.200 hedgehog
192.187.210.30 sanfran
Note If an NIS is in use (in a corporate network, for example), consult with the system administrator.
Note Enter 5120 for the LAN ports on all IGX ports.
Step 3 Configure the LAN port on the IGX node using a dumb terminal or an EIA/TIA-232 connection via the
workstation (using the vt command, as applicable) to enter the appropriate cnflan parameters.
The cnflan command configures the node’s communication parameters so that the node can
communicate with a Cisco WAN Manager terminal over an Ethernet LAN using the TCP/IP protocol.
The parameters contain address information about the Ethernet TCP/IP network that is used to connect
the Cisco WAN Manager workstation to an IGX node. The values used must conform to those of the
network and should be supplied by the Ethernet network administrator.
The cnflan command has the following parameters:
• IPAddr is the Internet Protocol address of the node used in the TCP/IP protocol.
• IPSubnetMask is a 32-bit mask. The default for a Class C LAN network is 255.255.255.0.
• TCPServicePort is the IGX LAN port number entered in the /etc/service file on the workstation. It
is 5120 for all IGX nodes.
• GatewayIPAddr is the Internet gateway address. This is the gateway that traffic is routed through
if the IGX node and workstation are on different networks. If they are on the same network, the
gateway is not used. The default “none” is displayed in this case. If a gateway IP is entered and later
you want to remove it, enter 192.0.0.0 opposite the prompt and “none” will again be displayed.
