IP OVER ATM AND LANE

This chapter describes working with the SmartSwitch ATM switch IP over ATM VLAN and emulated LAN 
capabilities. 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 VLAN

This section describes implementing IP over ATM on your SmartSwitch ATM switch. The following assumptions are 
made:

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)

Log into the switch, either through the terminal port or through the Ethernet interface by telnet.

Create a client on the switch and assign it as the ARP server for the VLAN.

SmartSwitch # add ipatmclient

ClientNumber(0) : 1 

ServerType(NONE) : local              

ServerAddress()  :

IPAddress()  : 90.1.1.1               

NetMask(255.0.0.0) : 255.255.255.0    

MTU(9180)  :

SmartSwitch # 

The example above creates a client on the switch, designates the client as the ARP server for the VLAN
(

 = 

), and assigns the client an IP address and subnet mask.

The command 

 always prompts you with a subnet mask that is 

appropriate for the IP address. However, if necessary, you can change the subnet 
mask to correspond to the strategy employed within your networks.

Never create an IP over ATM VLAN (or an IP over ATM client) with the same 
subnet as the ATM SmartSwitch Ethernet port.
