SmartSwitch ATM User Guide 2-12 IP OVER ATM AND LANEThis chapter describes working with the SmartSwitch ATM switch IP over ATM VLAN and emulated LANcapabilities. At the end of this chapter you will be able to use your SmartSwitch ATM switch to:• Create an IP over ATM VLAN• Create an emulated Ethernet LAN (LANE)2.1 CREATING AN IP OVER ATM VLANThis section describes implementing IP over ATM on your SmartSwitch ATM switch. The following assumptions aremade:• The SmartSwitch ATM switch will have a client on the IP over ATM VLAN• The ARP server will reside on the switch and correspond to the address of the switch client• All end nodes (computers, edge devices, and so on) support Switched Virtual Circuits (SVCs)1. Log into the switch, either through the terminal port or through the Ethernet interface by telnet.2. Create a client on the switch and assign it as the ARP server for the VLAN.SmartSwitch # add ipatmclientClientNumber(0) : 1ServerType(NONE) : local — the ARP server is assigned to the switch clientServerAddress() :IPAddress() : 90.1.1.1 — IP address is for example onlyNetMask(255.0.0.0) : 255.255.255.0 — subnet mask is for example onlyMTU(9180) :SmartSwitch #The example above creates a client on the switch, designates the client as the ARP server for the VLAN(ServerType = local), and assigns the client an IP address and subnet mask.Note The command add ipatmclient always prompts you with a subnet mask that isappropriate for the IP address. However, if necessary, you can change the subnetmask to correspond to the strategy employed within your networks.Caution Never create an IP over ATM VLAN (or an IP over ATM client) with the samesubnet as the ATM SmartSwitch Ethernet port.
