Tom,
A couple of things you can do to learn about IPX/SPX. First of all, the
Cisco book CISCO IOS Solutions for Network Protocols, Vol II: IPX,
AppleTalk, and More (or Cisco's web site) has a great detailed explanation
of SAPs. The other place you can look is perform a search on the
groupstudy.com archives.
SAP filtering is usually done on some well known SAP (Server Advertisement
Protocol) types. Unlike TCP/IP, IPX/SPX is a server-centric. Therefore,
the Netware servers continually advertise their service(s), such as File
Server (0x04), Print Server (0x07), Rconsole (0x6b), etc. So, you might be
asked to filter these in the future. This would be done by an IPX extended
access-list, which has an AL #900-999. I given an example below:
access-list 900 permit sap any all any 4
access-list 900 permit sap any all any 7
This would permit file and print SAPs, but deny everything else.
I hope that gets you started. You probably will not find too many experts
in IPX, since we live in an IP world :-)
Pat

Sorry for being a newbie. However, my experience with IPX/SPX is very
limited.
My questions is with regards to creating static SAPs. How do you determine
the socket number? Is this determined by the novell server application in a
live network. When creating them on the router for testing, I have been
picking random numbers. Should I be using 452 for SAP or 451 for NCP
depending on the type. Hope this makes since.
thanks,
