Chapter 2 Command Descriptions 225
set udpdest
Device support This command is supported in all devices.
Purpose Configures destinations for serial over User Datagram Protocol (UDP)
communication. These destinations are stored in the UDP destination
table.
The Digi One and PortServer TS devices are devices capable of UDP
multicast. UDP multicast is used to send serial data over an Ethernet cable
to one or many hosts at the same time. UDP is a connectionless protocol,
meaning this type of communication is not controlled by a higher-layer
application, but sends data without any form of acknowledgement or error
correction.
The number of entries allowed in the UDP destination table varies by
product.
The number of devices that can receive a UDP multicast varies by product.
• PortServer TS 8/16 Family: up to 16 devices can receive a UDP
multicast at one time.
• All other products, including the Digi One Family and
PortServer TS 1/2/4: up to 64 devices can receive a UDP multicast at
one time.
Both the transmitting and receiving devices must be configured properly for
UDP multicast to work.
Configuring UDP multicast communications involves configuring the Digi
device for the following types of connections:
• Inbound connections: connections initiated by the device on the other
side of the network.
• Outbound connections: connections initiated by the device connected
to the serial port.
Required
permissions
The root user can configure or remove UDP destinations. Normal users
