Binding a DDNS Policy to an Interface

Binding a DDNS Policy to an Interface


You can bind a DDNS policy to an interface to update the mapping between the domain name and an IP address and to start DDNS update.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run ddns apply policy policy-name [ fqdn domain-name ]

    The DDNS policy is bound to the interface.

    By default, no DDNS policy is bound to an interface.

    A maximum of six DDNS policies can be bound to an interface.

    • When the DDNS server is, or an HTTP-based common DDNS server, you must configure the fully qualified domain name (FQDN), that is, the fqdn parameter is mandatory.

    • The fqdn parameter is mandatory when the DDNS update mode defined by the RFC2136 is configured using the method ddns [ both ] command.

    • If the device functions as a DDNS client and multiple uplink service interfaces use different carriers' broadband services to access the network, you cannot bind a DDNS policy to the interfaces.
