ddns
DHCP Config Commands
Use this command to configure dynamic DNS parameters like domain name, enabling multi-user
class and IP address of the server.
Syntax
ddns [domainname (name)|multiple-user-class|server (IP address) (IP address)|
ttl <1-864000>|update-all]
Parameters
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 the DHCP server, FQDN is configured as DDNS domain name. This is used
internally in DHCP packets between the DHCP server on the switch and the DNS server.
Example
RFS7000(config-dhcp)#ddns domainname TestDomain.com
RFS7000(config-dhcp)#
RFS7000(config-dhcp)#ddns multiple-user-class
