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. 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 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.

• For information about J-Web or CLI monitoring, see the J-series Services Router Administration Guide.
• For SNMP monitoring with the DLSw MIB (defined in RFC 2024), you must configure SNMP on the router. For SNMP configuration instructions, see the J-series Services Router Administration Guide. For information about the DLSw MIB, see the JUNOS Network Management Configuration Guide.
