38CHAPTER 4: CONFIGURING BASIC SETTINGS
The following example illustrates how to assign an Internet address to a bridge.
Example Figure 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
1and 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

After assigning an Internet address to the bridge, go to Chapter 1 in the Using
Enterprise OS Software.
Assigning Internet If the bridge/router is used to route IP traffic, you must configure the ports on Addresses to a Router which IP packets are routed by assigning Internet addresses to them. You can
assign Internet addresses to individual ports using:
SETDefault !<port> 
For more information, see the Reference for Enterprise OS Software.
CAUTION: Do not assign an Internet address to port 0, or the IP routing function will be disabled.
The next example illustrates how to assign Internet addresses to a bridge/router or tunnel switch.
Example In Figure 4, Networks A and B are two different IP networks, and the bridge/router is used for routing IP packets and for bridging OSI packets. To assign an IP address to port 1, enter a command similar to the following:
SETDefault !1 
To assign an address to port 2, enter a command similar to the following:
