Cisco 500 Series Stackable Managed Switch Administration Guide
Enter the UDP Destination Port number for the packets that the switch is to relay.
Select the well-known port from the drop-down list or click the port radio button
to enter the number manually.
Enter the Destination IP Address that receives the UDP packet relays. If this field
is 0.0.0.0, UDP packets are discarded. If this field is 255.255.255.255, UDP packets
are flooded to all IP interfaces.
Click Apply. The UDP relay settings are written to the Running Configuration file.
The Domain Name System (DNS) translates user-defined domain names into IP
addresses for the purpose of locating and addressing these objects.
As a DNS client the switch resolves domain names to IP addresses through one or
more configured DNS servers.
Defining DNS Servers
Use the DNS Servers page to enable the DNS feature, configure the DNS servers
and set the default domain used by the switch.
Click IP Configuration > Domain Name System > DNS Servers. The DNS
Servers page opens.
Enter the parameters.
• DNS—Select to designate the switch as a DNS client which resolves DNS
names into IP addresses through one or more configured DNS servers.
• Default Domain Name—Enter the default DNS domain name (1–158
characters). The switch appends this to all non-fully qualified domain names
(FQDNs) turning them into FQDNs.
• Type—Displays the default domain type options:
- DHCP —The default domain name is dynamically assigned by the DHCP
server.
Static
- —The default domain name is user-defined.
