The switch can obtain its IP configuration automatically

using one of the following protocols:

?Bootstrap Protocol (BOOTP)

?Dynamic Host Configuration Protocol (DHCP)

?Reverse Address Resolution Protocol (RARP)

The switch makes BOOTP, DHCP, and RARP requests only if the

sc0 interface IP address is set to 0.0.0.0 when the switch

boots up. This address is the default for a new switch or a

switch whose configuration file has been cleared using the

clear config all command. BOOTP, DHCP, and RARP requests

are only broadcast out the sc0 interface.
