Introduction
This document provides a sample configuration for Data Link Switching (DLSw) Synchronous Data Link Control (SDLC) Physical Unit (PU) 2.1 and PU 2.0 multidrop.

Network Diagram
This document uses the network setup shown in this diagram:

Configurations
This document uses the configurations shown here:
|
RouterA |
|---|
hostname RouterA source-bridge ring-group 100 dlsw local-peer peer-id 1.1.1.11 dlsw remote-peer 0 tcp 1.1.1.12 interface TokenRing0 no ip address ring-speed 16 source-bridge 2564 1 100 source-bridge spanning interface Serial0 ip address 1.1.1.11 255.0.0.0 |

RouterB |
|---|
hostname RouterB dlsw local-peer peer-id 1.1.1.12 dlsw remote-peer 0 tcp 1.1.1.11 interface Serial0 ip address 1.1.1.12 255.0.0.0 interface Serial1 mtu 4400 no ip address encapsulation sdlc no keepalive clockrate 19200 sdlc role primary sdlc vmac 4000.1234.5600 sdlc N1 27200 sdlc address C1 sdlc xid C1 05DCCCC1 sdlc partner 4001.3745.1088 C1 sdlc address C2 xid-poll sdlc partner 4001.3745.1088 C2 sdlc dlsw C1 C2 |
Note:
-
You must use the sdlc role primary command for multidrop.
-
In the sdlc address C2 xid-poll command, xid-poll indicates that this PU is a 2.1 device.
-
The sdlc vmac 4000.1234.5600 command specifies the MAC address that represents the SDLC devices as if they are on a Token Ring (Logical Link Control [LLC]) network. The SDLC address of each PU is inserted into the last two bytes of the virtual MAC address.
-
The sdlc partner 4001.3745.1088 C1 command specifies the Host Token Ring MAC address, in this case, the Front End Processor (FEP).
-
The sdlc xid C1 05DCCCC1 command generates the Exchange Identification (XID) Format 0 Type 2 (F0 T2) for PU 2.0 devices.
-
The sdlc dlsw C1 C2 command binds these PUs to the DLSw+ feature.
Verify
There is currently no verification procedure available for this configuration.
Troubleshoot
This section provides information you can use to troubleshoot your configuration.
The sdlc test serial <slot/port> <sdlc pooling address> command, for example sdlc test serial 1 C1, can be used to determine whether the controller has been configured with the correct SDLC polling address and troubleshoot an incorrect configuration.
These debugs can be used to see what traffic is passed between the controller and the router for the purposes of troubleshooting:
-
debug sdlc events
-
debug sdlc packets
