CHAPTER 4
IP services

Domain Name System (DNS) commands allow you flexibility in setting up how the 5100/6100 

VDR interacts with your local or remote DNS server. You can configure a primary and secondary 

DNS server and set the amount of time that the 5100/6100 VDR waits for a response for the 

DNS server. You can also view your settings and changes.

Note. When you configure the loopback interface and the DNS settings, you must save 

all changes and reset the 5100/6100 VDR for changes to take effect. 

Figure 4-1 shows a remote DNS server at IP address 209.119.23.6 and a local DNS server at IP 

address 10.10.10.4. You can configure one as the primary and one as the secondary DNS host.

You can set a primary DNS server by issuing the set dns client primary_server command.
Syntax: set dns client primary_server <IP address>
Argument:

IP address in standard notation; specifies a primary server (public or private)
