Experimenter match fields
ONF assigned vendor ID is expected in the experimenter Field for all the OpenFlow messages containing the Experimenter Match fields.
0x00002481 is the HPE Vendor ID.
Controllers in the “oxm_field” of the Experimenter Match Fields in Flow Modification messages must use the following values:
OXM field |
Value |
|---|---|
UDP Source Port Range |
0 |
UDP Destination Port Range |
1 |
TCP Source Port Range |
2 |
TCP Destination Port Range |
3 |
TCP Flags |
4 |
Custom Match One |
5 |
Custom Match Two |
6 |
Custom Match Three |
7 |
Custom Match Four |
8 |
Values must be encoded post the Experimenter ID field in the OXM. For TCP Flags, the value and mask are each 16 bits in length. Similarly for Port Ranges, 16-bits are used to encode the Range Begin value followed by 16 bits for Range End value.
