Setting Up Network Information
Subnetting enables LAN administrators to create subnetworks that are transparent to the Internet. W ithin
networks, ONS 15454s often exist as subnetworks, which are created by adding a subnet mask to the
ONS 15454 IP address.
The following procedure tells you how to set up the esse nti al ON S 15 454 net work ing i nfo rmat ion.
Additional ONS 15454 networking information and procedures, including IP addressing exam ples, static
route scenarios and Open Shortest Path First (OSPF) protocol options are provided in Chapter 3, “IP
Networking.”
Procedure: Set Up Network Information
Step 1 From the CTC node view, click the Provisioning > Network tabs (Figure3-1).
Step 2 Complete the following:
•IP Address—Type the IP address assigned to the ONS 15454 node.
•Prevent LCD IP Config—If checked, prevents the ONS 15454 IP address from being changed using
the LCD. See the “Change IP Address, Default Router, and Network Mask Using the LCD”
procedure on page3-4.
•Default Router—If the ONS 15454 must communicate with a device on a netw ork to which the ONS
15454 is not connected, the ONS 15454 forwards the packe ts to t he de faul t rou ter. Type the IP
address of the router in this field. If the ONS 15454 is not connected to a LAN, leave the field blank .
•Subnet Mask Length—If the ONS 15454 is part of a subnet, type the subnet mask length (decimal
number representing the subnet mask length in bits) or click the arrows to adjust the subnet mask
length. The subnet mask length is the same for all ONS 15454s in the same subnet.
Note The MAC Address is read only. It displays the ONS 15454 address as it is identified on the
IEEE 802 Media Access Control (MAC) layer.
•Forward DHCP Request To—When checked, forwards Dynamic Host Configuration Protocol
requests to the IP address entered in the Request To field. DHCP is a TCP/IP protocol that enables
CTC computers to get temporary IP addresses from a server. If you enable DHCP, CTC computers
that are directly connected to an ONS 15454 node can obtain temporary IP addresse s from the DHCP
server.
•TCC CORBA (IIOP) Listener Port—Sets a listener port to allow communication with the ONS 15454
through firewalls. See the “Accessing ONS 15454s Behind Firewalls” section on page 2-12 for more
information.
