Login to the VLNC60/61/62.

Result:

The User EXEC prompt [(ALU switching)>] displays.

Enter the Global Config mode:

1. From the User EXEC prompt, enter enable to enter the Privileged EXEC mode.

2. From the Privileged EXEC prompt, enter configure to enter the Global Config mode.

Create the multilink interface and enter the Multilink Interface Config mode.

From the Global Config mode, enter interface multilink <multilink-number>, where multilink-number is a number in the range of 1-8. Default is none.

Example: (ALU Switching)(Config)# interface multilink 1.

Specify the IP address for the multilink interface.

From the Multilink Interface Config Mode, enter ip address <ip-address> <mask>.

Where:

• ip-address - Specifies the IP address of the interface.

• mask - Specifies the subnet mask of the IP address.

This is a mandatory parameter. The MLG cannot be enabled if this parameter is not configured. To change this parameter, the multilink interface must be disabled so that the new option information can be negotiated. The remote and local IP addresses must be in the same subnet.

Example: (ALU Switching) (Interface multilink-1)# ip address 152.148.10.10 255.255.255.0

An optional parameter may be used to specify offset and operation from the local IP address/mask to be used to generate the remote IP address of the MLG to be assigned to the remote end, via the IPCP Address Option.

From the Multilink Interface Config Mode, enter remote-ip-address-offset [add | subtract] <ip-address-offset>

Where:

• {add | subtract} - The operation to perform with offset-value to calculate remote IP address.

• ip-address-offset - Offset value to generate remote IP address of multilink interface. Range is 0-255.0-255.0-255.0-255. Default is 0.0.0.1.

If this parameter is not configured, the default will be an operation of add with a value of 1. Validation should check that the remote and local IP addresses are in the same subnet. To change this parameter, the multilink interface must be disabled so that the new option information can be negotiated from scratch.

Example: (ALU Switching) (Interface multilink-1)# remote-ip-address-offset add 0.0.0.2

Enable routing on the multilink interface.

From the Multilink Interface Config Mode, enter routing.

Example: (ALU Switching) (Interface multilink-1)# routing

Important!

The fragment-map specified in this command must already exist. See Procedure 18-2.1: Configure fragment map profiles.

Assign a pre-configured fragment-map which defines the maximum fragment size (per class). If no multiclass is configured, only fragment size 1 is applicable.

From the Multilink Interface Config Mode, enter assign-fragment-map <fragment-map-name> where fragment-map-name is in a range of 1-31 case sensitive alphanumeric character string.

This is a mandatory parameter. The MLG will not be allowed to be enabled if this parameter is not configured.

Example: (ALU Switching) (Interface multilink-1)# assign-fragment-map fragment-map-1

An optional command may be used to perform endpoint discriminator negotiation. Note that this command will only be accepted after a local IP address is configured on the bundle. This parameter is optional. If it is not specified, all links join the same bundle.

Refer to the multilink bundle-name endpoint command in the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide for details.

Example: (ALU Switching) (Interface multilink-1)# multilink bundle-name endpoint

Important!

The VLAN specified in this command must already exist. See Procedure 18-2.2: Configure VLANs for multilink group (MLG) interface.

An optional command may be used to map a VLAN to be pushed on traffic towards Ethernet links. If it is not specified, there will be no VLAN pushed on the traffic coming in from the multilink interface.

Refer to the service vlan <vlan number> command in the Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide for details.

Example: (ALU Switching) (Interface multilink-1)# service-vlan 10

By default, the short-sequence option on the multilink interface is enabled. If you want to disable it, from the Multilink Interface Config Mode, enter no multilink short-sequence.

To enable the short-sequence option, enter multilink short-sequence.

From the Multilink Interface Config Mode, enter no shutdown to enable the interface.

Example: (ALU Switching) (Interface multilink-1)# no shutdown.

Enter exit to return to the Global Config Mode.
