Cisco 500 Series Stackable Managed Switch Administration Guide
The UDP Relay feature is only available when the switch is in Layer 3 mode.
Switches do not typically route IP broadcast packets between IP subnets.
However, if configured, the switch can relay specific UDP Broadcast packets,
received from its IPv4 interfaces, to specific destination IP addresses.
To configure the relaying of UDP packets received from a specific IPv4 interface
with a specific destination UDP port, add a UDP Relay:
Click IP Configuration > Defining UDP Relay. The UDP Relay page opens.
Click Add. The Add UDP Relay page opens.
Select the Source IP Interface to where the switch is to relay UDP Broadcast
packets based on a configured UDP destination port. The interface must be one of
the IPv4 interfaces configured on the switch.
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.
