Configuring Data Link Switching

Data link switching (DLSw) was developed in the early 1990s as a method to transport IBM System Network Architecture (SNA) over a WAN network. To route traffic over a WAN link or the Internet, DLSw encapsulates the SNA network traffic in IP. The Services Router supports DLSw as part of an SNA implementation.

You must have a license to configure DLSw. For license details, see the J-series Services Router Administration Guide.

You use either the J-Web configuration editor or CLI configuration editor to configure DLSw. For more information on DLSw, see the JUNOS Services Interfaces Configuration Guide.
