Configuring Dns With Traceroute - Dell C9000 Series Networking Configuration Manual

dynamically learnt host and IP addresses. If the system cannot resolve the domain, it tries the domain name
assigned to the local system. If that does not resolve the partial domain, the system searches the list of
domains configured.
To configure a domain name or a list of domain names, use the following commands.
• Enter up to 63 characters to configure one domain name.
CONFIGURATION mode
ip domain-name name
• Enter up to 63 characters to configure names to complete unqualified host names.
CONFIGURATION mode
ip domain-list name
Configure this command up to six times to specify a list of possible domain names. The system searches
the domain names in the order they were configured until a match is found or the list is exhausted.

Configuring DNS with Traceroute

To configure your switch to perform DNS with traceroute, use the following commands.
• Enable dynamic resolution of host names.
CONFIGURATION mode
ip domain-lookup
• Specify up to six name servers.
CONFIGURATION mode
ip name-server ip-address [ip-address2 ... ip-address6]
The order you entered the servers determines the order of their use.
• When you enter the traceroute command without specifying an IP address (Extended Traceroute),
you are prompted for a target and source IP address, timeout in seconds (default is 5), a probe count
(default is 3), minimum TTL (default is 1), maximum TTL (default is 30), and port number (default is 33434).
CONFIGURATION mode
traceroute [host | ip-address]
To keep the default setting for these parameters, press the ENTER key.
Example of the traceroute Command
