Usage Guidelines

Usage Scenario

DNS provides static mappings between domain names and IP addresses. When IP addresses of interfaces change, DNS cannot dynamically update mappings. After the specified DDNS policy is applied on an interface, if the IP address of the interface changes, the DDNS policy updates mapping between the specified Fully Qualified Domain Name (FQDN) and the IP address.

If a DDNS policy with the same name is bound to an interface repeatedly and different FQDNs are specified, only the latest configuration takes effect and a DDNS update is initiated.

Prerequisites

To apply the policy on an interface, you need to create the DDNS policy first, also the DDNS policy, including DDNS Server domain-name, DDNS Client domain-name, username and password, must be completely configured.

Example

# Apply the DDNS policy "test "on the GigabitEthernet 0/0/1.

<sysname> system-view
[sysname] interface GigabitEthernet 0/0/1 
[sysname-GigabitEthernet0/0/1] ddns apply policy test
