Setting the DNS Domain Name and Address RS 2100 Initial Configuration
4.7 SETTING THE DNS DOMAIN NAME AND
ADDRESS
Associating a DNS name server with your RS 2100 allows you to use device names (rather than IP addresses) when
entering certain commands. For example, you can use a device’s name (which the DNS server knows) when using the
ping command.
If you want the RS 2100 to access a DNS server, use the following procedure to specify the domain name and IP
address for the DNS server.
1. Ensure that you are in Enable mode by entering the enable command in the CLI.
2. Use the ping command to verify that the RS 2100 can reach the DNS server:
Here is an example:
3. Enter Configure mode by entering the configure command in the CLI.
4. Enter the following command to specify the domain name for which the DNS server(s) have
authority:
For example: <domain-name> =
riverstone.com
5.
Enter the following command to add the DNS server to the RS 2100:
where <IP-addr> is the IP address of the DNS server(s). You can specify up to three DNS servers. Separate the
server IP addresses with commas.
6. Enter the save active command to activate the commands and enter yes to activate the changes.
Here is an example:
rs# ping 16.50.11.12 <IP address of the DNS server>
PING 16.50.11.12 (16.50.11.12): 56 data bytes
64 bytes from 16.50.11.12: icmp_seq=0 ttl=255 time=0 ms
