Setting Up Network Information
•
Time —If Use NTP/SNTP Server is not selected, type the current time in the format hh:mm:ss, for
example, 11:24:58. The ONS 15327 uses a 24-hour clock, so 10:00 PM is entered as 22:00:00.
• Time Zone —Click the field and choose the time zone from the pop-up menu.
Step 4
Click Apply .
Step 5
On the confirmation dialog box, click Yes .
Step 6
Review the node information. If you need to make corrections, repeat Steps 3 – 5 to enter the
corrections.
3.3 Setting Up Network Information
ONS 15327s almost always operate in network environments. Before you connect an ONS 15327 to
other ONS 15327s or to a LAN, you must change the default IP address that is shipped with each ONS
15327 (192.1.0.2). IP addresses are unique identifiers for devices—called hosts—that connect to TCP/IP
networks. Every IP address includes a network number, which is assigned to an organization, and a host
(device) number, which the organization’s LAN administrator assigns to an individual network device.
Subnetting enables LAN administrators to create subnetworks that are transparent to the Internet. Within
networks, ONS 15327s often exist as subnetworks, which are created by adding a subnet mask to the
ONS 15327 IP address.
The following procedure tells you how to set up the essential ONS 15327 networking information.
Additional ONS 15327 networking information and procedures, including IP addressing examples, static
route scenarios and Open Shortest Path First (OSPF) protocol options are provided in
Chapter 4, “IP
Networking.”
Procedure: Set Up Network Information
Step 1
From the CTC node view, click the Provisioning > Network tabs ( Figure 3-1 ).
Step 2 Complete the following:
•
IP Address —Type the IP address assigned to the ONS 15327 node.
•
Default Router —If the ONS 15327 must communicate with a device on a network to which the ONS
15327 is not connected, the ONS 15327 forwards the packets to the default router. Type the IP
address of the router in this field. If the ONS 15327 is not connected to a LAN, leave the field blank.
•
Subnet Mask Length —If the ONS 15327 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 15327s in the same subnet.
Note
The MAC Address is read only. It displays the ONS 15327 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 15327 node can obtain temporary IP addresses from the DHCP
server.
