I was recently trying to configure some port based VLAN's on a BS470 via JDM 5.8.3.0 and it did not work. After failing intitially, I went to the "Help" in Device Manager and made sure to follow the steps listed and it still failed. I was able to configure them using the browser interface without issue. Has anyone else seen this? I really don't want to configure these switches via the browser interface. Thanks for any insight.
