This chapter describes how to configure the interface between one gateway half and another gateway half. Gateway halves are one of the methods you can use to interconnect two separate networks. For information on configuring a node that is not a gateway half, use this manual.

Figure 9-1 “Gateway Half Link Screen Flow” shows the screen flow for configuring gateway half screens. Screens unique to gateway half configuration are indicated by bold boxed screens. [FUNCTION] denotes the function key used at a screen to invoke the next screen on the screen flow.

Configuring a node as a gateway half requires configuring two separate network interfaces: one for the interface between the two gateway halves, and a second for the gateway half's interface to its home network.

If this gateway half interfaces to a LAN, Token Ring, FDDI, 100VG-AnyLAN, or 100Base-T network, you should have already configured its network interface according to the instructions in Chapter 6 “Configuring a LAN, Token Ring, FDDI, 100VG-AnyLAN, 100Base-T Node” If this gateway half interfaces to a Point-to-Point or X.25 network, you should already have configured its NI according to instructions in Chapter 7 “Configuring a Point-to-Point Node” and Chapter 8 “Configuring an X.25 Node” respectively. If you have not, do so now and then return to this chapter.This chapter includes step-by-step instructions to help you perform the following tasks:

  • Begin the configuration process.

  • Configure a gatehalf.

Once the above tasks are completed, refer to Chapter 10 “Validating Network Transport and Cross-Validating with SYSGEN” for step-by-step instructions to help you perform the following validation tasks:

  • Validate the network transport configuration.

  • Cross-validate in SYSGEN.
