Example: Multiple Hosts on the Same Network over the Same
Communications Line
Your AS/400 system 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 AS/400 system appears as multiple hosts in a single
TCP/IP network (Figure 57).
This can be a migration scenario.
Example: Multiple Hosts on the Same Network over Multiple
Communications Lines
Your AS/400 system 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
addresses, your AS/400 system appears as multiple TCP/IP hosts in the same
TCP/IP network (Figure 58).
This scenario can be helpful for backup or to improve performance. However, there
is no dynamic backup or performance balance function.
