EXAMPLE NETWORKS52 CyberSWITCHC ONFIGURING THE IP I NTERFACE I NFORMATIONIn our example, we need to configure two types of interfaces. The LAN interface represents thesystem connection to the LAN IP Network 128.1.0.0. The WAN RLAN interface represents thesystem connection to the remote IP network 198.12.10.0.Press 2 at the IP main menu to begin the configuration of the IP interface information. Press 1 toadd an IP interface. Select the LAN interface option from the list of possible interface types.The interface name is a symbolic name given to the interface. For the LAN interface, use a namethat describes the LAN, such as the name of the site or department. Type CorpOffice for thisexample.You will then be asked for the IP address for the interface. In our example, the value you shouldenter is 128.1.1.1. You will then be asked for the IP subnet mask information. In our example, weare using a Class B address (without any subnetwork addressing) that requires 16 bits of theaddress to define the network number. Press to accept the default of “16” significant bits.Press to accept the default packet encapsulation type (Ethernet). Press to acceptthe default of 1500 as the MTU size.Press to accept the default transmit broadcast address. For almost all devices, this addresswill allow the transmission of the broadcast to all devices on the local network. For some olderdevices, you may need to try some of the other selections to get the transmission to work correctly.The rest of the LAN information requested pertains to the system’s RIP capability on the LAN (ifRIP is enabled). For the rest of the required RIP LAN interface information, accept the defaultvalues. If RIP is disabled, no RIP prompts will be displayed.The sequence of prompts will be similar to the following:
