Usage Guidelines
A DHCP client cannot perform updates for RR’s A, TXT and PTR. Use
update (dns) (override)
to enable the internal DHCP Server to send DDNS updates for resource records (RR’s) A, TXT and
PTR. The DHCP Server can always override the client, even if the client is configured to perform the
updates.
In the network pool of DHCP Server, FQDN is configured asa DDNS domain name. This is used
internally in DHCP packets between the switch’s DHCP Server and the DNS server.
Example
