6-20 CHAPTER 6: CONFIGURING BASIC SETTINGS
Assigning Internet
Addresses
This section describes how to assign one or more Internet addresses to the system
using the NETaddr parameter in the IP Service. Before you assign an Internet
address, you must determine:
■ Whether you want your network to connect to the Internet, and how to obtain
a unique Internet address.
■ Whether you want to use the system as a bridge, a router, or a bridge/router.
■ Whether you need subnet addressing.
If you have already decided on these issues, proceed to “Assigning Internet
Addresses to a Bridge” on page 6-20 or to “Assigning Internet Addresses to a
Router” on page 6-21. If you need more information to make your decision, refer
to “Obtaining an Internet Address” on page 6-21 and to the subnet information
in the Using NETBuilder Family Software.
Assigning Internet
Addresses to a Bridge
Even though a bridge does not route IP traffic, it needs an Internet address to
participate in network management and to be accessible from other devices
through Telnet or the SNMP.
When assigning an Internet address to an entire bridge, assign the address to
port 0 using:
SETDefault !0 -IP NETaddr = <IP address>
An Internet address assigned to port 0 is considered an Internet address for the
entire bridge.
The following example illustrates how to assign an Internet address to a bridge.
Example Figure 6-3 shows a configuration in which you need to assign an Internet address
to a bridge. Hosts A and B are two hosts belonging to the same IP network,
network 10. The IP host on Network A has an Internet address 10.0.0.1, and the
one on Network B has an Internet address 10.0.0.2. The bridge forwards packets
between these segments. To allow communication between the hosts and the
bridge, ports 1 and 2 must reside on the same network. Assigning the same
network number to two or more bridge ports is prohibited, so you must assign the
address to the entire bridge, entering a command similar to the following:
SETDefault !0 -IP NETaddr = 10.0.0.3
Figure 6-3 Assigning an IP Address to the Entire Bridge
After assigning an Internet address to the bridge, proceed to Chapter 1 in the
Using NETBuilder Family Software.
Assign IP address 10.0.0.3 to Port 0
for the IP hosts to access the bridge

= 10.0.0.1
