Applying the DDNS policy to an interface
After you apply the DDNS policy to an interface and specify the FQDN for update, the DDNS client
sends requests to the DDNS server to update the mapping between the domain name and the primary
IP address of the interface at the specified interval.
Before you apply a DDNS policy to an interface, complete the following tasks:
•
Specify the primary IP address of the interface and make sure the DDNS server and the interface
can reach each other.
•
Configure static or dynamic domain name resolution to translate the domain name of the DDNS
server into the IPv4 address. For more information, see "
Configuring the IPv4 DNS client ."
To apply the DDNS policy to an interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Apply the DDNS policy to the
interface to update the mapping
between the specified FQDN and
the primary IP address of the
interface, and enable DDNS
update.
ddns apply policy policy-name
[ fqdn domain-name ]
By default, no DDNS policy is
applied to the interface, no
FQDN is specified for update,
and DDNS update is disabled.
The
fqdn domain-name option
must be specified for all DDNS
servers except the PeanutHull
DDNS server.
NOTE:
If no FQDN is specified for the PeanutHull DDNS server, the DDNS server updates all domain names of the
DDNS client account. If an FQDN is specified, the DDNS server updates only the mapping between the
specified FQDN and the primary IP address.
Specifying the DSCP value for outgoing DDNS
packets
The DSCP value of a packet specifies the priority level of the packet and affects the transmission priority
of the packet. A bigger DSCP value represents a higher priority.
