Introduction


Digital Equipment Corporation developed the DECnet protocol to provide a way for its computers to communicate with one another. Currently in its fifth major product release, DECnet Phase V is a superset of the Open System Interconnection (OSI) protocol suite, it supports all OSI protocols, and it is compatible with the previous release (Phase IV). DECnet Phase IV Prime supports inherent MAC addresses, which allow DECnet nodes to coexist with systems that run other protocols that have MAC address restrictions. DECnet support on Cisco routers includes local-area and wide-area DECnet Phase IV routing over Ethernet, Token Ring, FDDI, and serial lines such as X.25, Frame Relay, and Switched Multimegabit Data Service (SMDS).

Use the commands in this book to configure and monitor DECnet networks.


Note Not all Cisco access servers support DECnet. For more information, refer to the release notes for the current Cisco IOS release.
