DNS Client
The Domain Name Service (DNS) client in the unit sends requests to a DNS server on
the WAN. The DNS requests get IP addresses required by the BSGX4e, such as the IP
address of a SIP server specified by FQDN. Two DNS servers can be configured: one
primary, the other as a secondary, backup server.
The DNS client determines the DNS configuration to use based on the current value
of its source parameter:
User: The DNS client uses the latest DNS configuration provided by the user.
DHCP: The DNS client uses the DNS configuration provided by the DHCP server.
PPP: The DNS client uses the DNS configuration provided by the PPP server.
NOTE: The command show system dns shows the DNS configuration currently in
use.
DNS Client Configuration Command
To configure the DNS client, enter the following command:
> config system dns
This command can:
Specify the source of the DNS configuration the client is to use (DHCP, or user).
The default is DHCP.
Specify a user-provided DNS configuration. This configuration is always stored,
but it is used only when the source parameter value is set to user.
Specify an optional domain name that is appended to every DNS request.
Table 13 describes the parameters of config system dns.
