: You can apply up to two of each of the different IPX ACLs (IPX, IPX RIP, and IPX 

SAP) to an IPX interface. When applying two ACLs of the same type, one ACL must 
govern the inbound traffic and the other must govern the outbound traffic.

A service access point (SAP) allows service-providing nodes (such as file servers and print 
servers) to advertise their services and addresses.

SAP makes the process of advertising and removing services dynamic. On the SSR, you 
can also add static IPX SAP entries. Through SAP, routers create and maintain a database 
of internetwork service information. This allows the clients on the network to determine 
which services are available on the network and to obtain the internetwork addresses of 
the nodes from which the clients can access those services. Because the SAP agent in each 
router keeps up-to-date information on available servers, a client wanting to locate the 
server can access a nearby router for the correct internetwork address.

The packet structure provided by SAP supports the following five functions:
