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

The subnet address mask associated with the in-band IP address shown on the screen 
(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

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

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
