Sep 12, 2016

The following operations can be performed on "dns srvRec":

add | rm | set | unset | show

add dns srvRec

Creates a service (SRV) record for the service offered by the specified target host, in the specified domain.

Synopsys

add dns srvRec <domain> <target> -priority <positive_integer> -weight <positive_integer> -port <positive_integer> [-TTL <secs>]

Arguments

domain

Domain name, which, by convention, is prefixed by the symbolic name of the desired service and the symbolic name of the desired protocol, each with an underscore (_) prepended. For example, if an SRV-aware client wants to discover a SIP service that is provided over UDP, in the domain example.com, the client performs a lookup for _sip._udp.example.com.

target

Target host for the specified service.

priority

Integer specifying the priority of the target host. The lower the number, the higher the priority. If multiple target hosts have the same priority, selection is based on the Weight parameter.

Minimum value: 0

Maximum value: 65535

weight

Weight for the target host. Aids host selection when two or more hosts have the same priority. A larger number indicates greater weight.

Minimum value: 0

Maximum value: 65535

port

Port on which the target host listens for client requests.

Minimum value: 0

Maximum value: 65535

TTL

Time to Live (TTL), in seconds, for the record. TTL is the time for which the record must be cached by DNS proxies. The specified TTL is applied to all the resource records that are of the same record type and belong to the specified domain name. For example, if you add an address record, with a TTL of 36000, to the domain name example.com, the TTLs of all the address records of example.com are changed to 36000. If the TTL is not specified, the NetScaler appliance uses either the DNS zone's minimum TTL or, if the SOA record is not available on the appliance, the default value of 3600.

Default value: 3600

Maximum value: 2147483647

rm dns srvRec

Arguments

domain

Name of the SRV record to be modified.

target

priority

Integer specifying the priority of the target host. The lower the number, the higher the priority. If multiple target hosts have the same priority, selection is based on the Weight parameter.

Minimum value: 0

Maximum value: 65535

weight

Weight for the target host. Aids host selection when two or more hosts have the same priority. A larger number indicates greater weight.

Minimum value: 0

unset dns srvRec

Use this command to remove dns srvRec settings.Refer to the set dns srvRec command for meanings of the arguments.

Synopsys

show dns srvRec

Displays the service (SRV) record configured for the specified target host and domain. If the domain name is not specified, all of the SRV records are shown.

Synopsys

show dns srvRec [(<domain> [<target>]) | -type <type>]

domain

Domain name for which to display the SRV record.

target

Target host for the specified service.
