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 -IP NETaddr = 10.0.0.3

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> -IP NETaddr = <IP address>

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 -IP NETaddr = 192.1.5.1

To assign an address to port 2, enter a command similar to the following:

SETDefault !2 -IP NETaddr = 192.1.3.1
