Inova Solutions OnTime 4-Digit Digital Clocks, Installation And User Manual

Page: 28 / 42

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 output.
The dhcpconfig command output below shows the settings that were received
from the DHCP Server using the configuration string in the first row of Table 6.
dhcpconfig
Using Option Code 230 for DHCP based Clock
Configuration.
The following DHCP based configuration settings are in
use:
Time Server : ntp.inovasolutions.com
Time Zone : -5
DST Rule : -1 8 2 2 1 1 10 2
Notes:
A clock must be re-booted to request a new configuration string from the
DHCP Server. The clock does not automatically request a new
configuration string at the expiration of the DHCP lease interval.
If private option 230 is not configured on the DHCP Server, the clock will
receive an IP address in the usual fashion but the clock‟s settings for Time
Server, Time Zone, DST, etc. will come from the default internal
configuration.
Appendix C contains an example of how to configure private options on a
Microsoft DHCP Server, such as the one that is bundled with Windows 2003
Server. It is for reference only. It is assumed that skilled IT personnel are the
only people authorized to edit DHCP Server settings.
