DNS Relay

Computer users usually prefer to use text names for computers they may want to open a connection with.
Computers themselves, require 32 bit IP addresses. Somewhere, a database of network devices' text names and
their corresponding IP addresses must be maintained.
The Domain Name System (DNS) is used to map names to IP addresses throughout the Internet and has been
adapted for use within intranets.
For two DNS servers to communicate across different subnets, the DNS Relay of the Switch must be used. The
DNS servers are identified by IP addresses.
Description
This field can be toggled between Enabled and Disabled using the pull-
down menu. It is used to enable or disable the BOOTP/DHCP Relay
service on the switch. The default is Disabled
This field allows an entry between 1 and 16 to define the maximum number
of router hops BOOTP messages can be forwarded across. The default hop
count is 4.
Allows an entry between 0 and 65535 seconds, and defines the maximum
time limit for routing a DHCP/BOOTP packet. If a value of 0 is entered, the
Switch will not process the value in the seconds field of the BOOTP or
DHCP packet. If a non-zero value is entered, the Switch will use that value,
along with the hop count to determine whether to forward a given BOOTP or
DHCP packet.
Description
The interface name of the IP interface on which the BOOTP or DHCP
servers reside.
Allows the entry of IP addresses for up to four BOOTP or DHCP servers.
