6. Host Names and DNS
88
ip name-server
Sets the name server referenced by the DNS resolver. A maximum of three name servers can be
specified. If multiple name servers are specified, inquiries to the name servers are performed in the
order in which they were set. Because the DNS resolver functionality is enabled by default, it
works as soon as the name server has been set.
Syntax
To set information:
ip name-server
<ip address>
To delete information:
no ip name-server
<ip address>
Input mode
(config)
Parameters
<ip address>
Specifies the IPv4 address of a name server in dot notation.
Default behavior
None
Impact on communication
None
When the change is applied
The change is applied immediately after setting values are changed.
If
no
ip
domain
lookup
is set, the change is applied to operation after
ip
domain
lookup
is entered.
Notes
1.
Set the IP address (
ip
name-server
) of the DNS server correctly. If the IP address of a DNS
server is not set correctly, it might take time until a communication failure with the DNS
server is detected when a host name is referenced, and operation might be affected (Example:
It takes time until the login prompt appears when a remote connection is established from
another switch to the Switch via Telnet).
One way to check the DNS server status is to use the
nslookup
command as shown below.
nslookup -retry=1 <name of host to be referenced> [<IP address of DNS server>]
If the IP address of a DNS server is correct, information about the specified host is displayed
as shown below.
Server: <host name of DNS server>
Address: <IP address of DNS server>
Name: <name of specified host>
Address: <IP address of specified host>
If the IP address of the DNS server is not correct, the following is displayed:
*** Can't find server name for address <IP address of DNS server>: Timed out
