LANE Config Server: 47.00817200000000E04BAAA006.00E04BAAA063.00 note: ** is the subinterface number byte in hex

Note The asterisks in this example indicate that the addresses are in hexadecimal. The ATM LANE module does not list these addresses with this command.

Configuring the LES/BUS

Follow these steps to configure a LES/BUS for two ELANS—the default ELAN and ELAN2:

1. Enter Global Configuration mode on the LANE module:

ATM#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

2.Enter Interface Configuration mode for the ATM0 interface, subinterface 1, and indicate whether the link is point−to−point or multipoint:

ATM(config)#interface atm0.1 point−to−point

3. Make this subinterface the Ethernet default LES/BUS and identify the ELAN:

ATM(config−subif)#lane server−bus ethernet ELAN2

Note You cannot configure more than one LES/BUS per subinterface.

4.Repeat Steps 2 and 3 for each LES/BUS you want to configure on this LANE module.

5.Enter Interface Configuration mode for the ATM0 subinterface 2:

ATM(config−subif)#interface atm0.2

6. Map the LES bus to the Ethernet ELAN named ELAN2:

ATM(config−subif)#lane server−bus ethernet ELAN2

ATM(config−subif)#end

Verifying the LES/BUS Configuration

To verify the configuration, issue the following command:

ATM#show lane server

LE Server ATM0.1 ELAN name: default Admin: up State: operational

LECS used: 47.007900000000000000000000.00A03E000001.00 NOT yet connected

ATM address: 47.00918100000000E04FACB401.00100DAACC41.02

LECS used: 47.007900000000000000000000.00A03E000001.00 NOT yet connected

Configuring a LEC for an ELAN

Follow these steps to configure two LECs for two ELANS—the default ELAN and ELAN2:

1. Enter Global Configuration mode on the LANE module:

ATM#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

2. Enter Interface Configuration mode for the ATM0 interface, subinterface 1:

179

ATM(config)#interface atm0.1

3. Map the LEC bus to the Ethernet ELAN named “default”:

ATM(config−subif)#lane client ethernet default

4.Repeat Steps 2 and 3 for each LEC you want to configure on this LANE module.

5.Enter Interface Configuration mode for the ATM0 subinterface 2:

ATM(config−subif)#interface atm0.2

6. Map the LEC bus to the Ethernet ELAN named ELAN2:

ATM(config−subif)#lane client ethernet ELAN2

ATM(config−subif)#end

Verifying a LEC Configuration on an ELAN

To verify the previous operation, issue the following command:

In the previous example, the state is initialState. This state indicates that the LEC is not yet a member of the ELAN. The zeroes in the ATM address columns are an indication that the LECS database has not yet been configured. This is normal—LECS will not come up until the LES/BUS is configured and the LECS database has been configured.

Configuring the LECS

Prior to configuring the LECS, you will need to go to each LES and get its ATM address. This address can be gathered with the following command:

ATM#show lane server

LE Server ATM0.1 ELAN name: default Admin: up State: operational type: ethernet Max Frame Size: 1516

ATM address:47.00918100000000E04FACB401.00100DAACC41.01

LECS used:47.007900000000000000000000.00A03E000001.00 NOT yet connected

Make a note of the address following the ATM address: label. To set up this LEC in a default unrestricted ELAN, perform the following commands:

1. Enter Global Configuration mode on the LANE module:

LANEMODULE#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

2. Configure a LANE database and specify the LANE database name with the following command:

LANEMODULE(config)#lane database LANE_DB

3.To bind the ELAN name to the ATM address of the LES/BUS for each ELAN, use the ATM address displayed when using the show lane server command:

LANEMODULE(lane−config−database)#name ELAN2 server−atm−address 47.00918100000000E04FCCB100.00100DAACC51.01

4.Repeat this step for each ELAN in the LANE network.

5.You can optionally specify an ELAN as the default ELAN. Doing so will allow the LECs not to be bound to an ELAN:

ATM(lane−config−database)#default−name default

ATM(lane−config−database)#end

Viewing the LANE Database

To see the results of the previous operation, issue the following command:

ATM#show lane database

LANE Config Server database table ÔLANE_Backbone’ default elan: default

elan Ôdefault’: un−restricted

server 47.00918100000000E04FACB401.00100DAACC41.01 (prio 0)

Binding the LECS Address to an Interface

After you have finished configuring the LECS database, use the following steps to configure the LECS address and bind it to the interface:

1. Enter Interface Configuration mode for ATM0 interface:

ATM(config)#interface atm0

2.Use the lane config auto−config−atm−address command to allow the ATM address to be computed automatically for the LECS:

ATM(config−if)#lane config auto−config−atm−address

3.Use the lane config database command to associate a database with the configuration server on the selected ATM interface:

181

ATM(config−if)#lane config database ELAN2

ATM(config−if)#end

Verifying the LECS Configuration

Verify the proper setup with the following command:

ATM#show lane config

LE Config Server ATM0 config table: ELAN2 Admin: up State: operational

LECS Mastership State: active master

list of global LECS addresses (58 seconds to update): 47.00918100000000E04FACB401.00100DAACC43.00

ATM Address of this LECS: 47.00918100000000E04FACB401. 00100DAACC43.00 (auto)

culprit for the last failure: 47.00918100000000E04FACB401. 00E04FACB070.04
