config global-dns-server zone
Use this command to configure DNS zone and resource records.
The DNS zone configuration is the key to the global load balancing solution. This configuration contains the key DNS server settings, including:
• Domain name and name server details.
• Type—Whether the server is the master or a forwarder.
• DNSSEC—Whether to use DNSSEC.
• DNS RR records—The zone configuration contains resource records (RR) used to resolve DNS queries delegated to the domain by the parent zone.
You can specify different DNS server settings for each zone you create. For example, the DNS server can be a master for one zone and a forwarder for another zone.
Before you begin:
• You must have a good understanding of DNS and knowledge of the DNS deployment in your network.
• You must have authority to create authoritative DNS zone records for your network.
• You must have read-write permission for global load balancing settings.
After you have configured a DNS zone, you can select it in the DNS policy configuration.

config global-dns-server zone
domain-name
The domain name must end with a period. For example: example.com.
negative-ttl
The last field in the SOA—the negative caching TTL. This informs other servers how long to cache no-such-domain (NXDOMAIN) responses from you. The default is 3600 seconds. The valid range is 0 to 2,147,483,647.
primary-server-ip
The IP address of the primary server.
primary-server-ip6
The IP address of the primary server.
primary-server-name
Sets the server name in the SOA record.
responsible-mail
Username of the person responsible for this zone, such as root.
ttl
The $TTL directive at the top of the zone file (before the SOA) gives a default TTL for every RR without a specific TTL set.
The default is 86,400. The valid range is 1 to 2,147,483,647.
type
• forward—The configuration allows you to apply DNS forwarding on a per-domain basis, overriding the forwarding settings in the “general” configuration.
• fqdn-generate—The configuration has been generated by the global load balancing feature set. You cannot configure this type manually.
• master—The configuration contains the “master” copy of data for the zone and is the authoritative server for it.
forward
• first—The DNS server queries the forwarder before doing its own DNS lookup.
• only—Only query the forwarder. Do not perform a DNS lookup.
forwarders
Specify a remote server configuration object.
dnssec-status
Enable/disable DNSSEC.
dnssec-algorithm
RSHSHA1 is the only supported algorithm.
dsset-info
It is generated by the system if DNSSEC is enabled for the zone.
dssetinfo-filename
The file is generated by the system if DNSSEC is enabled for the zone. The file generated by the zone configuration editor is the one you give to any parent zone or the registrar of your domain.
The convention is dsset-<domain>, for example dsset-example.com.
dsset-info-list
Specify a DSset info list configuration object.
KSK
Type characters for a string key. The file is generated by the system if DNSSEC is enabled for the zone.
KSK-Filename
The file is generated by the system if DNSSEC is enabled for the zone.
To regenerate the KSK, disable DNSSEC and then re-enable DNSSEC.
ZSK
Type characters for a string key. The file is generated by the system if DNSSEC is enabled for the zone.
ZSK-Filename
The file is generated by the system if DNSSEC is enabled for the zone.
To regenerate the ZSK, disable DNSSEC and then re-enable DNSSEC.
config a-aaaa-record
hostname
The hostname part of the FQDN, such as www.
source-type
• ipv4—Specify this option to configure IPv4 address information and weight.
• ipv6—Specify this option to configure IPv6 address information and weight.
ip
Specify the IP address of the virtual server.
ip6
Specify the IP address of the virtual server.
method
Weighted Round Robin is the only method supported.
weight
Assigns relative preference among members—higher values are more preferred and are assigned connections more frequently.
The default is 1. The valid range is 1-255.
config cname-record
alias
An alias name to another true or canonical domain name (the target). For instance, www.example.com is an alias for example.com.
target
The true or canonical domain name. For instance, example.com.
config mx-record
hostname
The hostname part of the FQDN for a mail exchange server, such as mail.
type
• IPv4
• IPv6
ip
Specify the IP address.
ip6
Specify the IP address.
priority
Preference given to this RR among others at the same owner. Lower values have greater priority.
config ns-record
domain-name
The domain for which the name server has authoritative answers, such as example.com.
host-name
The hostname part of the FQDN, such as ns.
type
• IPv4
• IPv6
ip
Specify the IP address of the name server.
ip6
Specify the IP address of the name server.
