Configuring the
SSR for IPX Routes
The Internetwork Packet Exchange (IPX) is a datagram connectionless protocol for the
Novell NetWare environment. You can configure the SSR for IPX routing and SAP. This
chapter
• provides an overview of IPX on the SSR.
• discusses creating IPX interfaces, which are bound to either a port or VLAN.
• discusses configuring static IPX SAP entries.
SAP allows service-providing nodes (such as file servers and print servers) to advertise
their services and addresses. You can configure static IPX SAP entries if you want to
add an entry for an IPX server to the IPX SAP table.
What Is IPX?
IPX, which is a datagram connectionless protocol, performs various tasks including
addressing, and routing and switching information packets from one location to another
on a network.
IPX defines internetwork and intranode addressing schemes. IPX internetwork
addressing is based on network numbers assigned to each network segment on a Novell
NetWare internetwork. The IPX intranode address comes in the form of socket numbers.
Because several processes are normally operating within a node, socket numbers provide
a way for each process to distinguish itself.
The IPX packet consists of two parts: a 30-byte header and a data portion. The network
node and socket addresses for both the destination and source are held within the IPX
header.
