Table 4: Examples of Common DHCP Configuration Strings

Setting a Different DHCP Option Number on a Clock

You do not have to use DHCP configuration option 230 for the clocks. You can also create
custom options using a different option number. Suppose private option 230 is already in
use on your DHCP server and you want to configure your clock to use another private option
instead, for example option 231. The ipconfig command can be used to set a different DHCP
option number on the clock or to disable this feature altogether. The ipconfig command is
defined in Appendix A.

Verifying the DHCP Configuration Settings on a Clock

The dhcpconfig telnet command lists all the configuration settings that were retrieved by
the clock from the DHCP server and that are currently in effect. If an error arises while
parsing the DHCP options received from the server, the error will be shown in the
command's output. Look on the next page for an example.
