Creating an Emulated LAN IP Over ATM and LANE

2.2CREATING AN EMULATED LAN

This section describes the steps for implementing an Emulated LAN (ELAN) on your SmartSwitch ATM switch.

Note If LANE services are to be reached through a virtual port on an ATM SmartSwitch, this switch must be a SmartSwitch 6500. Only the SmartSwitch 6500 supports logical multicasting. If LANE services are NOT reached through a virtual port, LANE services can reside on any ATM SmartSwitch.

The following assumptions are made:

•The ATM SmartSwitch 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 the Anycast 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 all SmartSwitch ATM switches. The ELAN name is “ELAN000.” To use this ELAN, start the LECS, configure your end nodes and edge devices to use ELAN name ELAN000, and then plug them into the ATM SmartSwitch.

1.Enter the start lecs command to activate LANE server services on this ATM SmartSwitch.

SmartSwitch # start lecs

NOTICE - 'LECS' ***** LECS started ***** — This assumes the LES/BUS is running (default)

SmartSwitch #

2.Create an ELAN on your ATM SmartSwitch by executing the add elan command. The following is an example.

SmartSwitch # add	elan
ELANNumber(0) : 1		— 1 is used instead of the default, (0)
ELANName(ELAN001): Marketing		— ELAN is named Marketing instead of the default, (ELAN001)
ConnectMethod(SVC):
ELANType(802.3)		—The default (Ethernet) is used
Multipoint(YES) :
MTU(1516) :
ErrorLogEnable(NO) :		— Take the default
MinimumTDEnable(NO) :		— Take the default
Distribute(PROXY)	:
SmartSwitch #

3.Use the add laneclient command to create a client for the switch on the ELAN:

SmartSwitch # add laneclient
ClientNumber(0) :1	— One is used instead of the default, (0)
LanName(ELAN001) : Marketing	— ELAN name is Marketing, not the default, (ELAN001)
ServerType(LECS) :
ServerAddress()	— No LANE server address is specified; see note below
IPAddress() : 90.1.1.1	— IP address and subnet mask are specified only as examples

NetMask(255.0.0.0): 255.255.255.0

MTU(1516) :
