When enabled, UDP Echo generates UDP packets that contain the unit serial number and ID,
and transmits them to the specified IP address and port at the configured interval. When the unit
receives a UDP packet at a local port configured for UDP echo, it will “echo” the packet back to
the sender.There may be more than one UDP echo instance available on the unit. Instance 0 is used
when specifying the local port to listen on.
Using the Web Page(s)
Destination IP address:
The IP address that UDP echo packets should be sent to. If this parameter is left blank, UDP
Echo is disabled.
Destination port:
The destination port UDP echo packets should be sent to.
Local port:
The local port on the unit that should listen for UDP echo packets. If any UDP packets are sent
to this port, the unit will send a copy back to the IP address and port they were sent from.
Echo request interval (s):
This parameter specifies the interval at which the unit will send UDP echo packets to the
Destina tion IP address and Destination port specified above.
Use routing code to determine echo interface:
When this parameter is set to “No”, the interface used to send UDP echo packets will be
specified in the Interface and Interface # parameters below. In this instance, the interface must
already be connected for the packets to be sent. When set to “Yes”, the routing code is used to
determine the best interface to send the UDP echo packets on. The interface will be connected
if necessary before the packets are sent.
Only send when interface is in service:
When this parameter is set to “Yes”, and Use routing code to determine echo interface is set to
“No”, UDP packets will not be sent if the Interface is out of service.
Exclude data from UDP packet:
When this parameter is set to “No”, UDP echo packets will contain the unit’s serial number and
ID in textual form. When set to “Yes”, the packet will only contain a single byte of data of value
0. This keeps the size of the packets down, which is useful if the interface has high data charges
(e.g. GPRS).
Interface:
This parameter specifies which interface the UDP echo packets should be sent from. If set to
“None”, UDP echo packets will not be sent unless Use routing code to determine echo inter-
face is set to “Yes”. Other options are “PPP” and “ETH”.
Interface #:
This parameter specifies which instance of the Interface defined above should be used to send
UDP echo packets on.
