# unable to create sfc port pairs .

i get the below error when i try to create a sfc port pair. ( i am using stable pike version)

pmanda@ctl:~$openstack sfc port pair create --ingress p2 --egress p2 PP1 create_port_pair_postcommit failed. Neutron server returns request_ids: ['req-ec2ba301-86e7-4b0f-bc02-5008f503d0aa'] pmanda@ctl:~$

i have enabled the sfc in netron.conf and upgraded the db

[DEFAULT] service_plugins = flow_classifier,sfc

[sfc] drivers = ovs

[flowclassifier] drivers = ovs

i have enabled the sfc ont the computes by changing the openvsitch_agent.ini file.

[agent] extensions = sfc

below are the debug logs , i see delete a port pair is tried which fails. why delete a port pair when i want to create one.
