3-8CHAPTER 3: CONFIGURING THE ATM BACKBONE SWITCHMODULE

 

LECs 2 through 8 are set to the following parameter values:

 

Configuration mode is Manual.

 

Interface mode is Disabled.

 

ELAN Name is None.

 

Vbridge assignment is Unassigned.

 

 

Configuring LAN

The procedure you use to configure the LAN Emulation parameters for

Emulation

a LAN Emulation Client depends on whether the LEC is configured for

Parameters

automatic or manual configuration.

Automatic

By default, the configuration mode of LEC 1 of the ATM Backbone

Bridgeport-LEC

SwitchModule is set to Automatic. Upon initial power-on, a LEC that is

Configuration

set to Automatic configuration mode attempts to establish connection

Mode

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.

Manual If the module cannot successfully autoconfigure, use the following Bridgeport-LECprocedure to manually configure the required initial parameters.

Configuration

Mode

1Configure 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
