Nigel,
The purpose of the static SAPs you're creating is to create dummy
entries pointing to dummy services. These dummy services need to have a
socket number of what the service is trying to emulate. The socket number
for SAP is what the router will use in the actual SAP packet sent out once a
minute. This SAP packet will use a SAP socket number, but the records
inside the SAP packet will reference the socket numbers that you entered in
the static entry. Hope this helps.

Subject: IPX undocumented secrets....
Hi All,
I've just begun to place a spin on my IPX preparation and I must =
admit things seem a little more confusing now more than ever. Caslow's =
book gives a lot of very specific information on IPX itself which is =
been helpful but now I'm trying to understand how most of what I'm =
currently looking at comes together to enable IPX as a routing protocol. =
=20
What I'm trying to understand is in creating static SAP entries the =
command is
ipx sap <service type> <name> <network.node> <socket> <hop count>
Now in looking at Caslow's book pg. 499 he list the IPX Socket Numbers =
that direct data encapsulation to the appropriate upper layer protocols =
as follows;
0x451 - NCP
0x452 - SAP
0x453 - RIP=20
0x455 - NETBIOS
0x456 - Diagnostic
0x457 - Serialization
0x4001 - =20
0x7FFF - Client Socket Numbers
0x85BE - IPX EIGRP
0x9001 - NLSP
0x9004 - IPXWAN
0x9086 - IPX PING
In listing this I'm trying to understand lab examples where the =
requirement calls for static SAP entries that make use of various IPX =
sockets namely 0x451. I'm thinking since there's a socket for SAP why =
and how come the other IPX sockets are used in SAP entries....?
Nigel..
