Detailed Information

 

Novell IPX

 

Internetwork Packet Exchange (IPX) is the NetWare Layer 3 protocol used to route packets through interconnected networks. IPX specifies a connectionless datagram, similar to the IP packet of Transmission Control Protocol/Internet Protocol (TCP/IP) networks.

 

IPX network addresses consist of two parts: a network number and a node number. The IPX network number is assigned by the network administrator; the node number is usually the Media Access Control (MAC) address for a network interface in the end node.

 

IPX exchanges routing information using RIP, a dynamic distance-vector routing protocol. With the release of NetWare 3.12 and 4.x, Novell added support for NLSP, a link-state routing protocol.

 

IBM SNA

 

The Catalyst 4224 now supports the following IBM SNA features:

 

  • DLSw
  • Async
  • Bisync
  • STUN

 

Support

 

Cisco IOS software release 12.1(5)YI follows the standard Cisco support policy as indicated in the following link.
