Network uses 1’s for broadcast addresses? y

Common Fields

Network uses 1’s for broadcast addresses?

See Common Data Module Fields (256) for descriptions of fields on this screen that are not listed below.

This field allows you to specify whether the DEFINITY system is to use all 1’s or all 0’s in the host ID to form broadcast addresses sent on the network by this C-LAN board.

Valid	Usage
Entries
y/n	Leave the default (y) if the private network contains only
default is y	DEFINITY switches and adjuncts. Set to n only if the network
	includes non-DEFINITY switches that use the 0’s method of
	forming broadcast addresses, as described below.
	The binary form of a broadcast address is most commonly formed by
	combining the (sub)network portion with all 1’s for the host portion
	of the address. However, some non-DEFINITY older systems form
	broadcast addresses using 0’s instead of 1’s in the host portion.
	These systems usually recognize a received broadcast message as
	such only if the message address is formed using the 0’s method.
	For a broadcast message received, the C-LAN board recognizes
	either form as a broadcast address and therefore accepts (looks at)
	the message. For a broadcast message sent, the C-LAN board uses
	the 1’s method if this field is set to y and uses the 0’s method if this
	field is set to n.
	If one or more nodes in the network is a non-DEFINITY switch that
	uses the 0’s method, then every DEFINITY switch in the network
	that wishes to broadcast to these 0’s-method switches must set this
	field to n.
