Name Server Parameters

ParameterDescription
IndexSpecifies the index value for the name server. Each name server instance must have a unique index number. The range allowed is 0 to 7.
PortSpecifies the port number to use on the name server. The range is 1 to 65535 and the default is 53.
PrioritySpecifies a priority for the name server. The range is 0 to 100 and the default is 0.
Weight

Specifies a weight for the name server. The range is 0 to 100 and the default is 0.

Name servers with the same priority are prioritized based on the following formula: W/SW, where W = the weight of the name server and SW = the sum of the weights of the name servers having the same priority.

HostnameSpecifies an FQDN of up to 128 characters for the name server. If you specify a host name (FQDN), the IP address is resolved using the system name server assigned to the SBC management interface.
IP Address V4 or V6Specifies an IPv4 or IPv6 address for the name server.
