Cisco Systems ONS 15327 manual Setting Up General Network Information, Changing the IP Address

78-11719-02 July 2001 Using Cisco Transport Controller 3

Step 7 Convert the longitude, originally given in decimal degrees, to the Wdddmmssfff format. In the example, 122.615536 = W1223655000. Enter zeros if degrees are less than 100, for example, 98 degrees is entered 098.

3.8 Setting Up General Network Information

This section explains how to set up general network information. For procedures that configure networks, see Chapter 4, “Configuring Networks.”

3.8.1 Changing the IP Address

Before you connect an ONS 15327 to other ONS nodes or to a LAN, you must change the default IP address that is shipped with the ONS 15327 (192.1.0.2). IP addresses are unique identifiers for nodes or hosts connected to a network using TCP/IP. Each address consists of a network number and a host number. The network numbers are used for routing, while the host number is used to address an individual host within the network or subnetwork. A subnet mask is used to extract network and host information from the IP address.

IP addresses are 32-bit binary numbers. However, to make IP addresses easier to work with, they are represented as four decimal values, each representing eight bits in the range 0 to 255 (known as octets) and separated by decimal points. For example, the following IP address is in binary format:

10001100.10110011.11011100.11001000

The same address, represented as four decimal values, is:

140.179.220.200

Because the IP addresses that you work with represent binary addresses, changing an address is not always straightforward. Therefore, before you change the ONS 15327 IP addresses, consult your LAN administrator or someone knowledgeable in TCP/IP to ensure addresses are suitable to your network. See Chapter 7, “Network Management” and Chapter 6, “Ethernet Applications” for additional information.

Procedure: Set Up Network Information

Step 1 Display the CTC node view.

Step 2 Click the Provisioning > Network tabs (Figure 3-17).

Step 3 Enter the following information:

•IP Address—Type the node IP address.

•Default Router—If the ONS 15327 must communicate with a device that has an IP address that the ONS 15327 is not routed to, it forwards the packets to the default router. Type the address of the router in this field. If the ONS 15327 is not connected to a LAN, leave this field blank.

•Subnet Mask Length—Type the subnet mask length (decimal number representing the subnet mask length in bits), or click the arrows, to adjust the subnet mask length.

•MAC Address (read only)—Displays the ONS 15327 address as it is identified on the Media Access Control layer.
