IP source addresses

Numbering must start from 1 i.e. r2ukl101 would have IP address (0 is reserved for the network address). There is no limitation for the layer 2 address but uniquness must be ensured, i.e. each port in the experiment must have its own layer 2 address.

Ethernet = Layer 2 = Hardware source addresses

Please use the global prefix 00:CC:BB::: for the first three bytes. The fourth byte represents again the subsystem (it is identical to the third byte in the IP address). The fifth byte is again the running number of your board. The sixth byte is reserved and will be set by the FPGA firmware according to the port-number, which is used for sending.

Ethernet destination address to be used in all TELL1 / UKL1


This should be configured on each board wanting to send on the data network. Using any other address will usually not work (packets will be dropped).

IP destination address to be used

The prefix (the first two bytes) is 192.168 (for farm nodes). The last two bytes are assigned by the TTC. In the config file you can set them to 0.0. If you are not using the TTC then you must give the full data-network address of a farmnode. You can find the address using the host command. E.g.: for hlte0801 the data network address will be given by typing host hlte0801-d1

Sample configuration for a TELL1 .cfg file

_L0003:___    []         --Destination IP, The two last bytes are normally replaced by TTC/ECS info. This is =hlt00101= 
_L0004:___  0x[00:01:e8:22:4b:bb] --Destination MAC
_L0005:___    []         --Source IP (this is r2ukl101 - do not use1)
_L0006:___  0x[00:CC:BB:01:01:00] --Source MAC the last byte is replaced by the port number 0..3
_L0007:___  0x[     800]    --Ethernet type(16b)
_L0008:___  0x[       4]    --IP version number(4b)
_L0009:___  0x[       5]    --Internet header length in 32-bit words(4b)
_L0010:___  0x[       0]    --Type of desired service for IP packet(8b)
_L0011:___  0x[      FF]    --Time in seconds for IP packet to stay in the Ethernet(8b)
_L0012:___  0x[      F2]    --Next level protocol(8b)

This can be used as part of a file to run daq_tell1 for simple tests. Note please do not send blindly to a farm node. Make sure it is not in use by somebody else. Please: For any test on the DAQ network check with the Online team first.
