Configuration Prerequisites; Configuration Procedure; Applying The Ddns Policy To An Interface - HP 6125XLG Layer 3-Ip Services Configuration Manual

Configuration prerequisites

Visit the website of a DDNS service provider, register an account, and apply for a domain name for the
DDNS client. When the DDNS client updates the mapping between the domain name and the IP address
through the DDNS server, the DDNS server checks whether the account information is correct and
whether the domain name to be updated belongs to the account.

Configuration procedure

To configure a DDNS policy:
Step
1. Enter system view.
2. Create a DDNS policy and enter
its view.
3. Specify a URL address for DDNS
update requests.
4. Specify the username to be
contained in the URL address.
5. Specify the password to be
contained in the URL address.
6. (Optional.) Specify the parameter
transmission method for sending
DDNS update requests to
HTTP/HTTPS-based DDNS
servers.
7. (Optional.) Associate an SSL client
policy with the DDNS policy.
8. (Optional.) Specify the interval for
sending update requests.

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
