(DNS)
preference
Select a DNS server preference from the list
or select Manual to specify DNS settings
manually.
The DNS settings of the preferred
DNS information source will only be
applied if the corresponding
interface address configuration
method is used. For example, to
apply IPv6 DNS information for Port
A requires the IPv6 address
configuration for Port A to be set to
Automatic.
Specifies a name for the ISDN Gateway.
Depending on your network
configuration, you may be able to
use this host name to communicate
with the ISDN Gateway, without
needing to know its IP address.
The IP address of the name server.
server
Identifies an optional second name server.
The secondary DNS server is only
used if the first is unavailable. If the
first server returns that it does not
know an address, the secondary
DNS server will not be queried.
(DNS suffix)
Specifies an optional suffix to add when
performing DNS lookups.
This option can allow you to use
non-fully qualified host names when
referring to a device by host name
instead of IP address.
For example, if the domain name is
set to cisco.com, then a request to
the name server to look up the IP
address of host endpoint will actually
lookup endpoint.cisco.com.
