Table 10 IP Configuration/Setup screen fields (continued)

Field	Description
In-Band Subnet	The subnet address mask associated with the in-band IP address shown on the screen
Mask	(see In-Band Switch IP address field). Network routers use the subnet mask to
	determine the network or subnet address portion of a host’s IP address. The bits in the
	IP address that contain the network address (including the subnet) are set to 1 in the
	address mask, and the bits that contain the host identifier are set to 0.
	Default Value	0.0.0.0 (no subnet mask assigned)
	Range	Four-octet dotted-decimal notation, where each octet is represented
		as a decimal value, between 0 and 255, separated by a decimal
		point
Default Gateway	The IP address of the default gateway.
	Default Value	0.0.0.0 (no IP address assigned)
	Range	Four-octet dotted-decimal notation, where each octet is represented
		as a decimal value, between 0 and 255, separated by a decimal
		point

Choosing a BootP request mode

The BootP Request Mode field in the IP Configuration screen allows you to choose which method the switch uses to broadcast BootP requests:

•BootP When Needed

•BootP Always

•BootP Disabled

•BootP or Last Address

Note: Whenever the switch is broadcasting BootP requests, the BootP process will eventually time out if a reply is not received. When the process times out, the BootP request mode automatically changes to BootP Disabled mode. To restart the BootP process, change the BootP request mode to any of the three following modes:

•BootP When Needed

•BootP Always

•BootP or Last Address.
