Usage guidelines
A DDNS update request is initiated immediately after the primary IP address of the interface changes or
the link state of the interface changes from down to up.
If you set the interval to 0, the device does not periodically initiate any DDNS update request, but initiates
a DDNS update request when the primary IP address of the interface changes or the link state of the
interface changes from down to up.
If you use the interval command multiple times with different time intervals, the most recent configuration
takes effect. If you change the interval for an applied DDNS policy, the device immediately initiates a
DDNS update request and sets the interval as the update interval.
Examples
# Set the interval for sending DDNS update requests to one day and one minute for the DDNS policy
steven_policy.
<Sysname> system-view
[Sysname] ddns policy steven_policy
[Sysname-ddns-policy-steven_policy] interval 1 0 1
