Parameters
Usage Guidelines
Use
update dns override to enable an internal DHCP server to send DDNS updates for
resource records (RRs) A, TXT and PTR. A DHCP server can always override the client even if the
client is configured to perform the updates.
In the DHCP server network pool, FQDN is defined as the DDNS domain name. This is used
internally in DHCP packets between the DHCP server on the controller and the DNS server.
Example
RFController(config-dhcp)#ddns domainname TestDomain.com
RFController(config-dhcp)#
RFController(config-dhcp)#ddns multiple-user-class
RFController(config-dhcp)#
RFController(config-dhcp)#ddns ttl 1000
RFController(config-dhcp)#
