Note If configured devices fail to join the VLAN, see Chapter 4, Section 4.2.2, “UNI Routes.” Also, see Chapter 5, Section 5.1, “Troubleshooting IP Over ATM.”

You have completed the process for creating an IP over ATM VLAN. Continue to the next section for instructions on creating an emulated LAN or go to Chapter 4, “Switch Administration,” for information about SmartCell 6A000 switch operations and maintenance.

3.1.1ATM Addressing for IP over ATM

The SmartCell 6A000 provides a default format for ATM addresses used by IP over ATM. The default format is constructed as follows:

netprefix + two zero bytes + IP address of the device (in hex) + a trailing zero byte

Where the netprefix is constructed from

39 + nine zero bytes + the last three bytes of the device’s MAC address

For instance, if the switch’s MAC address is 00:20:D4:14:41:80 and the switch’s client IP address is 90.1.1.1, then the 20-byte ATM address of the ARP server is

39:00:00:00:00:00:00:00:00:00:14:41:80:00:00:5A:01:01:01:00

Where 39:00:00:00:00:00:00:00:00:00:14:41:80 = netprefix 00:00 = two trailing zeros

5A:01:01:01 = IP address 90.1.1.1 in hexadecimal 00 = trailing zeros byte

3.2CREATING AN EMULATED LAN

This section describes the steps for implementing an Ethernet Emulated LAN (ELAN) on your SmartCell 6A000 switch. The following assumptions are made:

The SmartCell 6A000 switch will contain a client on the ELAN.

All end nodes (computers, edge devices, other switches, and so on) support the Well Known LECS Address or can obtain the address of the LECS using ILMI.

All end nodes support Switched Virtual Circuits (SVCs).

Note An ELAN comes pre-configured on SmartCell 6A000 switches. The ELAN name is “ELAN000.” To use this ELAN, start the LECS, configure your end nodes and edge devices to use this ELAN000, and then plug them into the SmartCell 6A000.
