Specifying The Local System Domain And A List Of Domains; Configuring Dns With Traceroute - Dell S6100 Configuration Manual

To view the current configuration, use the show running-config resolve command.
Specifying the Local System Domain and a List of
Domains
If you enter a partial domain, Dell Networking OS can search different domains to finish or fully qualify that partial domain.
A fully qualified domain name (FQDN) is any name that is terminated with a period/dot. Dell Networking OS searches the host table first to
resolve the partial domain. The host table contains both statically configured and dynamically learnt host and IP addresses. If Dell
Networking OS cannot resolve the domain, it tries the domain name assigned to the local system. If that does not resolve the partial
domain, Dell Networking OS 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. Dell Networking OS 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
The following text is example output of DNS using the traceroute command.
