a. Select the + Add Row button to add individual options. Assign each a Global DHCP Option
Name to help differentiate it from others with similar configurations. Select the radio
button of an existing option and select Delete to remove it from the list.
b. Assign a Value to each option from 1 - 254. A vendor-specific option definition only applies
to the vendor class for which it’s defined.
19. Define the following set of Dynamic DNS (Not Applicable for Static Bindings) parameters used
with the network pool configuration. Using DDNS controllers and service platforms can instruct
a DNS server to change, in real time (ad-hoc) the active DNS configuration of its configured
hostnames, addresses or other information stored in DNS.
20. Click the + Add Row button and enter a Destination and Gateway IP Address to add Static
Routes Installed on Clients.
21. Select OK to save the updates to the DHCP pool’s Advanced settings. Select Reset to revert the
screen back to its last saved configuration.
Defining DHCP Server Global Settings
Set a DHCP server global configuration by defining whether BOOTP requests are ignored and DHCP
global server options.
To define DHCP server global settings:
1. Select DHCP > Server Policy from within Services menu pane.
2. Select the Global Settings tab.
DDNS Domain Name Enter a domain name for DDNS updates representing the forward zone in the DNS server. For example,
test.net.
DDNS TTL Select this option to set a TTL (Time to Live) to specify the validity of DDNS records. The maximum value
configurable is 864000 seconds.
DDNS Multi User Class Select the check box to associate the user class option names with a multiple user class. This allows
the user class to transmit multiple option values to DHCP servers supporting multiple user class
options.
Update DNS Set if DNS is updated from a client or a server. Select either Do Not Update, Update from Server or
Update from Client. The default setting is Do Not Update, implying that no DNS updates occur at all.
DDNS Server Specify a numerical IP address of one or two DDNS servers. Dynamic DNS (DDNS) prompts a computer
or network to obtain a new IP address lease and dynamically associate a hostname with that address,
without having to manually enter the change every time. Since there are situations where an IP address
can change, it helps to have a way of automatically updating hostnames that point to the new address
every time.
