Requirements
Before attempting this configuration, please ensure that you meet these requirements:
-
The router must be running the IBM feature set.
-
The DLSw peers must be configured.
-
Both ends of the connection must be serial interfaces supporting SDLC.
Components Used
This document is not restricted to specific hardware and software versions.
