Pause controller action in Open vSwitch

Question

I am trying to instruct the switch to pause as described in http://www.openvswitch.org/support/dist-docs/ovs-ofctl.8.txt.

It is said that the action should be controller(key=value), I assume that pause is the key and True is the value. I tried issuing, for example, the following command: (switch name c2)

sudo ovs-ofctl add-flow c2 dl_dst=00:00:00:00:00:01,actions=controller:pause=True

but it does not work, writing that pause is unrecognized key.

What version of Open vSwitch are you using (`ovs-ofctl --version`)? — pchaigno, May 14 '18 at 10:41

It looks like support for the pause controller action was added in the version 2.6.0 of Open vSwitch. Otherwise, the following syntax should work:

sudo ovs-ofctl add-flow c2 "dl_dst=00:00:00:00:00:01,actions=controller(pause)"

Thank you. That was indeed the problem. I upgraded OVS and this worked. Do you know how can I send such command with POX? – Daniel May 14 '18 at 13:18
Glad I could help! No idea for POX, I've never used it. – pchaigno May 14 '18 at 13:32
I don't know. I don't use controllers very often. – pchaigno May 15 '18 at 12:35
