Configuring LAN
Emulation
Parameters
The procedure you use to configure the LAN Emulation parameters for
a LAN Emulation Client depends on whether the LEC is configured for
automatic or manual configuration.
Automatic
Bridgeport-LEC
Configuration
Mode
By default, the configuration mode of LEC 1 of the ATM Backbone
SwitchModule is set to Automatic. Upon initial power-on, a LEC that is
set to Automatic configuration mode attempts to establish connection
with the LECS according to established autoconfiguration guidelines.
Refer to Chapter 2, LAN Emulation Overview, for more information.
After the automatic bridgeport-LEC configuration is complete, you must
assign the LEC to a vbridge. Only one bridgeport LEC from the same
ATM Backbone SwitchModule may be assigned to each virtual bridge.
In this example, LEC 1 of a ATM Backbone SwitchModule in slot 4 is
assigned to vbridge 2:
CB5000>
set bridge_port 4.1 vbridge 2
Before the LEC can exchange data, a bridgeport on the Ethernet or
FDDI SwitchModule must also be assigned to the vbridge.

Bridgeport-LEC
Configuration
Mode
If the module cannot successfully autoconfigure, use the following
procedure to manually configure the required initial parameters.
1
Configure initial ATM Backbone SwitchModule parameters using the
commands in the following example (configuring LEC 1 on a module in
slot 4):
CB5000>set bport_lec 4.1 mode disable
CB5000>set bridge_port 4.1 vbridge 2
CB5000>set bport_lec 4.1 config_mode manual
CB5000>set bport_lec 4.1 les_atm_address <address>
CB5000>set bport_lec 4.1 elan_name <name>
(may not be required)
CB5000>set bport_lec 4.1 mode enable
