CREATING 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.
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
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) :
