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 primary 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 primary 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
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. primary—The configuration contains the “primary” copy of data for the zone and is the authoritative server for it.
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	IP address of the primary server.
primary-server-ip6	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.
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. Note: You can specify the @ symbol to denote the zone root. The value substituted for @ is the preceding $ORIGIN directive. A hostname can contain alphanumeric characters such as a–z, A–Z, and 0–9, but must NOT end with - (hyphen) or . (period). You can also use * (wild card) in a domain name.
source-type	IPv4 or IPv6
ip	IP address of the virtual server.
ip6	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 or IPv6
ip	IP address of the mail server.
ip6	IP address of the mail server.
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 or IPv6
ip	IP address of the name server.
ip6	IP address of the name server.
config txt-record
name	Hostname. TXT records are name-value pairs that contain human readable information about a host. The most common use for TXT records is to store SPF records.
text	Comma-separated list of name=value pairs. An example SPF record has the following form: "v=spf1 +mx a:colo.example.com/28 -all" If you complete the entry from the CLI, put the string in quotes. (If you complete the entry from the the Web UI, you do not put the string in quotes.)
config srv-record
hostname	The SRV Hostname.
target-server	The target server name (record).
config ptr-record
PTR Address	A PTR address, such as 10.168.192.in-addr.arpa. or 1. If you use the number, the domain name is in the format "x.x.x.in-addr.arpa.".
FQDN	A fully qualified domain name, such as "www.example.com".
