Reset Balance One Ethernet port remotely?

I’m trying to debug a VLAN / ethernet / DNS problem, and it would be really handy if I could power cycle or otherwise reset an ethernet port in software, in order to force an IOT device to re-acquire DHCP settings.

Right now, I have to go physically yank the power from the IOT device.

Is there a way to do this from either the normal or support.cgi interfaces?

Apparently you can do this.

Navigate to Network / LAN / Port Settings, click the Edit button, toggle the Enable button, then Save, then Apply changes:

Then reverse the steps.

Although this works, it takes about 30 seconds, since the “Apply Changes” process is fairly slow.
