Configuring Dynamic DNS Updates for Clients

You can enable DDNS updates when creating or editing a DHCP scope for

Distributed, L3

clients. When enabled, the DDNS updates of the clients are periodically sent during the

specified time to the DNS server that is configured in the DHCP profile. If there is no DNS

server configured in the DHCP profile, the client DNS updates will be dropped. The DDNS

updates are secured by using TSIG shared secret keys, when communicating between the

client and the server. For more information, see

Configuring Distributed DHCP Scopes

(Page 284).

key
