Thanks Mohan,
After setting service_plugins and adding sfc tables to neutrondb, I can
create port-pair, port-pair-group but classifier creation still claim a
logical-source-port parameter.
neutron flow-classifier-create --ethertype IPv4 --source-ip-prefix
55.55.55.2/32 --destination-ip-prefix 55.55.55.9/32 --protocol tcp
--source-port 22:22 --destination-port 1:65000 FC1
ERROR:
neutron flow-classifier-create: error: argument --logical-source-port is
required
Try 'neutron help flow-classifier-create' for more information.
Please someone can explain what does --logical-source-port correspond to ?
Does the classifier require port-create like SF ?
Regards,
