For more information on DHCP options, go to

http://www.ietf.org/rfc/rfc2131.txt?number=2131 or

http://www.ietf.org/rfc/rfc2132.txt?number=2132.

Note	The configuration file value for SNTP server address and SNTP GMT offset can
	be configured to override the DHCP value. Refer to
	tcpIpApp.sntp.address.overrideDHCP in Time Synchronization <sntp/> on page
	A-51.
	The CDP value can be obtained from a connected Ethernet switch if the switch
	supports CDP.
	In the case where you do not have control of your DHCP server or do not have
	the ability to set the DHCP options, an alternate method of automatically
	discovering the provisioning server address is required. Connecting to a
	secondary DHCP server that responds to DHCP INFORM queries with a
	requested boot server value is one possibility. For more information, refer to
	http://www.ietf.org/rfc/rfc3361.txt?number=3361 and
	http://www.ietf.org/rfc/rfc3925.txt?number=3925.
