[ovs-discuss] How to bring a patch port down?

[Krishna Pratap]

Hi,

I am trying to use the "ovs-ofctl mod-port switch port <action>" command to
bring down the patch port I have on my switch . I am using the patch port
to create a link between two switches. I am using ovs 2.1 version.

When I use the command "ovs-ofctl mod-port br1 port1 down" the patch port
on switch doesn't go down.


When I use the command with veth pair ports it works fine. I wanted to know
if I am doing anything wrong or patch port is not supported.

Thanks
KP
