In the network illustrated in Example network domain, the switch at 10.28.192.1 is configured to use DNS names for DNS-compatible commands in the pubs.outdoors.com domain. The DNS server has been configured to assign the host name docservr to the IP address used by the document server (10.28.229.219).
Configuring switch "A" with the domain name and the IP address of a DNS server for the domain enables the switch to use host names assigned to IP addresses in the domain to perform ping and traceroute actions on the devices in the domain. To summarize:
|
Entity |
Identity |
|---|---|
|
DNS server IP address |
10.28.229.10 |
|
Domain name (and domain suffix for hosts in the domain) |
|
|
Host name assigned to 10.28.229.219 by the DNS server |
docservr |
|
Fully qualified domain name for the IP address used by the document server (10.28.229.219) |
|
|
Switch IP address |
10.28.192.1 |
|
Document server IP address |
10.28.229.219 |
With the above already configured, the following commands enable a DNS-compatible command with the host name docserver to reach the document server at 10.28.229.219.
As mentioned under DNS resolver operation, if the DNS entry configured in the switch does not include the domain suffix for the desired target, you must use the target host's fully qualified domain name with DNS-compatible commands. For example, using the document server in Example network domain as a target:
