8.4.7 UDP Heartbeat Packet
The 922-MES card will continuously transmit a broadcast heartbeat User Datagram Packet (UDP) from uC DIAG
with diagnostics information after power-up and card initialization is completed. The data is printed out as comma
separated text (ASCII) and a network capture utility (e.g. Wireshark) can be used to capture this data. The UDP
heartbeat can be used, for example, to identify cards in cases where the IP information has been lost.
The card can output the UDP heartbeat in two different packet lengths: short (normal) and long (extended). Both
the short and long UDP packet contains the following diagnostics information:
On-board sensors (board temperature, humidity, ON time counter, OFF event counter)
uC DIAG data
o
Network settings and configuration (IP address, Subnet Mask, Gateway, DNS, DHCP)
o
Analog data (on-board 5V voltage rail and board current)
o
Board serial information (including serial number, date code, FW version, MAC address)
The long UDP packet includes all the information from the short packet plus the following diagnostics information:
Link status of copper ports CU1-CU8 and SFP1-SFP2.
Device error codes
By default the UDP heartbeat feature is enabled and the card transmits the short UDP packet every five (5)
seconds. This interval can be adjusted to any value between 1 and 253 seconds through Telnet.
The table below shows an example of the diagnostics information contained in each type of UDP packet. The
heartbeat packet type can be changed through Telnet by sending the co
mmand “
hcfg long
” for extended
packets or “
hcfg short
” for short packets.
