AppleTalk Node Numbers
Each device interface, which uses AppleTalk protocol, is required to have a
unique AppleTalk node number on that network, conventionally written in
decimal.
❏
Example
194
Node numbers are separated into two ranges (on LocalTalk only):
❏
Node numbers 1 to 127
This range identifies 'user' nodes. These are nodes which are
frequently switched on and off (for example, Macintosh computers).
❏
Node numbers 128 to 254
This range identifies 'server' nodes. These are nodes normally
engaged in time consuming tasks and are seldom switched off (for
example, a gateway).
Configuration of node numbers is optional. If
not
configured, a node number is
dynamically assigned by the node itself when switched on. If a node number
is
configured and, in error, a number is selected which is already assigned to
another node on the same network, then the node will dynamically re-assign
itself another number.
Figure 1-12 shows two device interfaces which use AppleTalk protocol. Each
device interface has a unique node number.
