DSPU HOST or SNA HOST

[whecox]

I took a CISCO SNA class several years ago. There was a section on DSPU which i recently reviewed. There have been additional features and options added since I took that class. I saw some examples that use the "SNA HOST" configuration command. Can someone tell me why I would use SNA HOST rather than DSPU HOST? Are there any tutorials available on recent CISCO SNA enhancements such DSPU, SNA, SNASW.

Regards,

"dspu" is the downstream PU gateway function. "sna" is a subset of the dspu function to provide a service point on the router. This is a SNA PU that can receive NetView RUNCMDs. Our host-based ISM management product uses RUNCMDs primarily to manage our routers. If you want both functions, just add the "focalpoint" keywordto the end of the "dspu host" config. If you just want the service point for management, use "sna host". And if you just want the PU gateway without service point, use "dspu host" and leave off the "focalpoint" keyword.

SNASw provides APPN functionality. Along with LU 6.2 communications, it provides for dependant LUs downstream using the APPN DLUR function. Upstream to the host is an APPN connection, which may be over an IP network by using HPR/IP, also known as enterprise extender. More information is available by starting at http://www.cisco.com/go/snasw .

Let us know if you have more specific questions after looking this over.
