Hi,
I will suggest that you use postman API and add the postman collections from
here, the "GET all node" collection will give you the node. Note that you will need to supply the URL with controller IP and port, and have done the number 1 item as described by Ravi above.
Also note that OVSDB works with MD-SAL as well and the correct command to retrieve the database is "printcache
" node in the form of "OVS|192.168.1.1:4432"
Hope this help.
