Good product, especially for the price. Perfectly manages VLAN except that the internal management port does not support a tagged VLAN. Too bad also that management requires special software, not a simple web access, this app is more shoddy and causes NIC crash during standby outputs. Negative also in POE management, since it is impossible to switch the power ports which prevents de facto hard-resetter remote IP camera, for example, is the only big awkward gap. Why I take a star. But at this price, you can not complain too much, this switch is stable, powerful and fits seamlessly into an existing VLAN infrastructure.
