Configuring a DNS Entry
The switch allows one DNS server entry, which includes the DNS server IP
address and the chosen domain suffix. Configuring the entry enables the use
of
ping
and
traceroute
with a target’s host name instead of the target’s IP
address
.
Syntax: [no] ip dns server-address < ip-addr >
Configures the IP address of a DNS server accessible to the switch. This setting
identifies the server to use for DNS resolution to the target IP address, and must be
configured before
ping or traceroute can be executed with host name criteria.
The switch supports one DNS server entry. Configuring another IP address for this
value replaces the current IP address with the new one.
The
no
form of the command replaces the configured IP address with the null setting,
which disables host name resolution. (Default: null)
Syntax: [no] ip dns domain-name < domain-name-suffix >
Configures the domain suffix that is automatically appended to the host name
entered with the
ping or traceroute command. When the domain suffix and the DNS
server IP address are both configured on the switch, you can execute
ping
and
traceroute
with only the host name of the desired target within the domain. In either
of the following two instances, you must manually provide the domain identifica­
tion by using a fully qualified DNS name with each
ping
and
traceroute
command:
• If the DNS server IP address is configured on the switch, but the domain suffix
is not configured (null)
• The domain suffix configured on the switch is not the domain in which the target
host exists
The switch supports one domain suffix entry. Configuring a new entry for this value
replaces the current suffix.
The
no
form of the command replaces the configured domain suffix with the null
setting. (Default: null)
Example Using DNS Names with Ping and Traceroute
In the network illustrated in figure C-21, the switch at 10.28.192.1 is configured
to use DNS names for
ping and traceroute 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).
