Re: [sfc-dev] SFC-103 demo error

Swati,
Can you also dump the SFC classifier configuration. These REST commands should do it: 

   curl -H "Content-Type: application/json" -X GET --user admin:admin
   http://localhost:8181/restconf/config/ietf-access-control-list:access-lists
   | python -m json.tool

   curl -H "Content-Type: application/json" -X GET --user admin:admin
   
http://localhost:8181/restconf/config/service-function-classifier:service-function-classifiers
   | python -m json.tool


Just change localhost to the IP of where ODL is running if its not on 
the same machine.


Thanks,

Brady

Hi


 I am trying to get SFC-103 demo using stable/boron ODL, can't get 
packet path to work. could you please help



 I am not using the automated demo.sh, instead manually setup all the 
nodes as per the topology explained in README file.



 ovs is installed from 
(https://github.com/yyang13/ovs_nsh_patches.git) on nodes classifier1, 
classifier2, SFF1 and SFF2.


Configured service nodes, SF, SFF, SFC, SFP and RSP  from SFC-GUI

ACL and service classifier configured using REST conf (apidoc/explorer 
, unable to configure using GUI, gives 404 error)


 ovswitch flow rules get installed correctly in SFF1 and SFF2.

 however openvswitch flow rules are not getting installed in 
openvswitch of classifier1 and classifier2 nodes.



 Could you please provide pointers to fig out why flows are not 
getting setup in classifier1 and classifier2 nodes??


Regards,
Swati

Here is the config exported from SFC UI
