hi, Ben:
Thanks for your reply, it really works with the following command:
ovsdb-client transact
"[\"Open_vSwitch\",{\"mutations\":[[\"ports\",\"delete\",[\"uuid\",\"508cd3d7-a29c-47c3-80df-cdff04228cf9\"]]],
\"table\":\"Bridge\",
\"where\":[[\"_uuid\",\"==\",[\"uuid\",\"a24d9a54-c30c-4224-906d-d0af73c53094\"]]],
\"op\":\"mutate\"}]"
Then there is another question, how can I delete a port with its name? As you
see, in the above command, I must use the "uuid" to delete port from bridge
table. Is there a simple way to use "select" and "mutate" to delete port with
name? like this:
ovsdb-client transact
"["Open_vSwitch",{"mutations":[["ports","delete",["uuid","{"columns":["_uuid"],"table":"Port","where":[["name","==","p0"]],"op":"select"}"]]],
"table":"Bridge",
"where":[["_uuid","==",["uuid","a24d9a54-c30c-4224-906d-d0af73c53094"]]],
"op":"mutate"}]"
