You can view the SAP traffic coming in and going out of the server by typing track on at the UnixWare command line. The output is displayed directly to the UnixWare console unless redirected. Type track off to stop viewing the packet traffic. See the track(1Mipx) manual page for details.
To view packet traffic for RIP, SPX, or NCP, you will need to use a LAN analyzer.
Other utilities that may be helpful are ipxinfo(1ipx) and nwsapinfo(1ipx).
