The higher-layer protocols make no distinction between the VDLC and any other data-link control, but they do identify the VDLC as a destination. In the example shown in Figure 129, SNASw has two ports: a physical port for Token Ring and a virtual port for the VDLC. When you define the SNASw VDLC port, you can specify the MAC address assigned to it. Data transport from SNASw to DLSw+ by way of the VDLC is directed to the VDLC MAC address. The type of higher-layer protocol you use determines how the VDLC MAC address is assigned.

DLSw+ Configuration Task List

DLSw+ supports local or remote media conversion between LANs and SDLC or QLLC.

To configure DLSw+, complete the tasks in the following sections:

•Defining a DLSw+ Local Peer for the Router, page 288

•Defining a DLSw+ Remote Peer, page 289

•Mapping DLSw+ to a Local Data-Link Control, page 292

•Configuring Advanced Features, page 295

•Configuring DLSw+ Timers, page 310

See the “DLSw+ Configuration Examples” section on page 312 for examples.

Defining a DLSw+ Local Peer for the Router

Defining a DLSw+ local peer for a router enables DLSw+. Specify all local DLSw+ parameters as part of the local peer definition. To define a local peer, use the following command in global configuration mode:

Command	Purpose
Router(config)# dlsw local peer [peer-id	Defines the DLSw+ local peer.
ip-address] [group group] [border] [cluster
cluster-id] [cost cost] [lf size] [keepalive
seconds] [passive] [promiscuous]
[init-pacing-window size] [max-pacing-window
size] [biu-segment]

The following is a sample dlsw local peer statement:

dlsw local peer peer-id 10.2.34.3
