Data link switching (DLSw) was developed in the early 1990s as a method to transport IBM System Network Architecture (SNA) over a WAN. 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.
Note: You must have a license to configure DLSw. For license details, see the J-series Services Router Administration Guide.
You can use either J-Web Quick Configuration or a configuration editor to configure DLSw. For more information about DLSw, see the JUNOS Services Interfaces Configuration Guide.
To monitor DLSw on a Services Router, you can use J-Web or CLI monitoring tools or SNMP.
