Configuring the LAN Port
Note Configure the LAN parameters before connecting the node to a LAN.
Note Refer to the Cisco WAN Manager Operations publication and the Cisco WAN Switching
Command Reference publication for additional information
Step 1 Contact asystem administrator to obtainIP addresses forthe workstationand for theIGX
node.
Step 2 Normally, the system administrator updates the NIS database, as applicable (if an NIS is
used), and adds the IP addresses for the workstation and node to the NIS database. Refer
to the Cisco WAN Manager Operations publication for instructions on configuring the
Cisco WAN Manager workstation.
• 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 containaddress information about the Ethernet TCP/IP
networkthat isused toconnect theCiscoWANManager workstation toanIGX node.The
values used must conform to those ofthe network and should be suppliedby 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.
