Note: This configuration works for either a Physical Unit (PU) 2.0 or PU 2.1 Synchronous Data Link Control (SDLC) device. Mixing the PU type is supported in IOS 11.1.

The SDLC controller runs nonreturn to zero (NRZ) encoding, which is the default on the router.

WAN and IP routing configurations are not shown in this document (for simplicity).

Refer to Basic DLSw+ Configurations for more information.
