Addressing and management concepts

...................................................................................................................................................................................................................................
Introduction
To enable management, the WaveStar® ITM-SC must have addressing and
management connection information for each NE under its control. The basic
information concerning such topics as addressing and management connection
information are given in this section; however, much more detailed information about
all of these Data Communications Network (DCN) concepts can be found in
"Management communication
Data communications network
The Data Communications Network (DCN) is a general name for the collection of
various communication means between network management devices, such as the
ITM-SC, and the NEs. By providing the communication between management systems
and the NEs, the DCN makes management possible. For further information,

DCN addresses
The NE has two addresses in the DCN:
• Ethernet address
• NSAP address
Ethernet address
The Ethernet address is the unique 6-byte address of a network element. Sometimes it
is also referred to as the hardware or physical address of the node. The Ethernet
address has only local meaning on the Q-LAN and cannot be used for routing
purposes. It does not contain the information on where the node is in the Data
Communications Network.
NSAP address
The Network Service Access Point (NSAP) address is used by the network protocol for
location information. The NSAP address of a node is its DCN wide identifier which
uniquely identifies the node in the network. Although different NSAP formats exist, it
is preferable that all nodes in a network should use the same address structure.
Complete details concerning the structural formatting of the NSAP address can be
found in
