I've enabled the AP's Management VLAN and lost GUI access, how can I regain access?

Enabling Management VLAN on the AP effectively separates management traffic from user data traffic, but if the device is accessed from a network that is not VLAN-tagged with the VLAN ID configured on the ePMP AP, management access is unavailable.

Instead of factory-defaulting the ePMP AP to regain access, operators may also access the device by IP  In the latter case, configuration is retained on the ePMP AP.
