ddns apply policy

Use ddns apply policy to apply a DDNS policy to an interface to update the mapping between the FQDN and the primary IP address of the interface, and to enable DDNS update.

Use undo ddns apply policy to remove the application of a DDNS policy from an interface and to stop DDNS update.

Syntax

ddns apply policy policy-name [ fqdn domain-name ]

undo ddns apply policy policy-name

Default

No DDNS policy and FQDN for update are specified on the interface, and DDNS update is disabled.

Views

Interface view

Predefined user roles

network-admin

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 specifies a case-insensitive string of 1 to 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 VLAN-interface 2 to update the domain name to IP address mapping for FQDN www.whatever.com and enable DDNS update.

<Sysname> system-view
[Sysname] interface vlan-interface 2
[Sysname-Vlan-interface2] ddns apply policy steven_policy fqdn www.whatever.com
