	Field	Conditions/Comments
	Subnet Mask	Enter the subnet mask associated with the IP address for
		this IP interface. (The IP address is associated with the
		node name on the Node Names screen).
		Since the node-1 and node-5 IP interfaces are on the same
		network (192.168.1), they must be assigned the same
		subnet mask.
		In this example, the subnet mask 255.255.255.224 divides
		the network 192.168.10 into 6 (usable) subnets. This
		C-LAN IP Interface (node-5) is on the first subnet. See
		Switch 1 Task — Assign IP Interfaces (page 77) for an
		explanation of this subnet. See Subnetting (page 16) in
		Chapter 1 for a detailed description of subnetting.
	Gateway Addr	Leaving this field blank adds a level of network security
		for this IP interface but requires that IP routes be
		administered to enable communication with nodes on
		different (sub)networks.
	Net Rgn	Enter the region number for this IP interface.
