Note: The maximum number of interfaces that can be active on a line description

at any given time is 128. This is true for all line types (for example,

token-ring, Ethernet, frame relay, and so forth).

Example: A Single Host on a Network over a Communications

Line

Your server uses one adapter for TCP/IP to attach to a LAN or WAN network. You

add one TCP/IP interface. This TCP/IP interface includes the Internet address of

your server. With this single Internet address, your server is part of a single

TCP/IP network (Figure 47).

Example: Multiple Hosts on the Same Network over the Same

Communications Line

Your server uses one adapter for TCP/IP to attach to a LAN or WAN network. You

add multiple TCP/IP interfaces. Each of these TCP/IP interfaces includes an

Internet address of the same TCP/IP network. With these multiple Internet

addresses your server appears as multiple hosts in a single TCP/IP network

(Figure 48).

This can be a migration scenario.

Example: Multiple Hosts on the Same Network over Multiple

Communications Lines

Your server uses more than one adapter for TCP/IP to attach to the same LAN or

WAN network. You add multiple TCP/IP interfaces. At least one interface is

assigned to each adapter/line description. Each of these TCP/IP interfaces includes

an Internet address of the same TCP/IP networks. With these multiple Internet
