Use undo ddns apply policy to remove the DDNS policy applied to the interface and stop DDNS update.
Syntax
ddns apply policy policy-name [ fqdn domain-name ]
undo ddns apply policy policy-name

Parameters
policy-name: Specifies the DDNS policy name, a case-insensitive string of 1 to 32 characters.
fqdn domain-name: Specifies the FQDN to replace <h> in the URL for DDNS update. The domain-name
argument consists of dot-separated case-insensitive strings of 1 to 63 characters, such as aabbcc.com.
The total length of the domain-name argument cannot exceed 253 characters. It can include letters,
digits, hyphens (-), underscores (_), and dots (.).
Usage guidelines
You can apply up to four DDNS policies to an interface.
If you use the ddns apply policy command multiple times with the same DDNS policy name but different
FQDNs, both of the following occur:
• The most recent configuration takes effect.
• The device initiates a DDNS update request immediately.
Examples
# Apply the DDNS policy steven_policy to GigabitEthernet 2/1/1 to update the domain name to IP
address mapping for FQDN www.whatever.com and enable DDNS update.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/1/1
[Sysname-GigabitEthernet2/1/1] ddns apply policy steven_policy fqdn www.whatever.com
