I am working with Broadcom’s OFDPA, and it makes use of Experimenter messages
and match fields. I cannot find any Ryu documentation or examples of how to
do this. I suspect that the OFPExperimenterOxmId class is used but again I
can’t find an example. The Ryu source code doesn’t make it clear either.
What the OFDPA documentation gives me are the constants to use. Specifically,
I have the following values to use:
The Experimenter OUI is “00-10-18”. The Experimenter Match field value for
the type OVID is “10” (decimal) and its value is a 16-bit integer. This value
is set in one table and then matched in another table.
If OVID were part of the OpenFlow specification the parser was using what I
would write would look like this for the match rule.
match = parser.OFPMatch(in_port = match_in_port,
vlan_vid = vlan_parameter,
ovid = outer_vlan_id
)
Obviously that won’t work since “ovid” is not a parameter OFPMatch understands.
So using the vendor-defined constants above, how do I code that in Ryu?
For the set action the question is the same except with a different class.
Again, the nominal code would be:
action = parser.OFPActionSetField(ovid = action_set_ovid)
Much thanks for any assistance.
