5.2.1.4 Configuring DHCP Server DDNS Values
The DHCP Server screen’s Configuration tab can be used to display an additional DDNS screen. Use this
screen to define a DDNS domain name and address for use with the switch.
To configure a global domain name and DDNS server address:
1. Select Services > DHCP Server from the main menu tree.
2. Highlight an existing pool name from within either the Configuration or Host Pool tabs and click the
DDNS button at the bottom of the screen.
3. Enter a Domain Name which represents the forward zone in the DNS server. For example test.net.
4. Define the TTL (Time to Live) to specify the validity of DDNS records. The maximum value is 864000
seconds.
5. Use the Automatic Update drop-down menu to specify whether the automatic update feature is on or
off. Select Server update to enable a DDNS update from the DHCP server. Select Client update to get
the DDNS updates from DHCP clients.
NOTE: For an additional (in depth) discussion on the DDNS setup options available on the
switch (using both the switch CLI and Web UI), refer to Chapter 7 of the Migration Guide
available for download from the corporate website.
