<p class="MsoNormal">extnet is mapped to the OVSbridge br-ex, which has a physical interface that’s trunked to all of the available VLANs..trying this command on the other available VLANs works, but 1 and 2 (the ones I want to test on) always fails. Is there
anything obvious to try on the system itself or is this more likely a network issue?
