I am familiar with configuring VLANs on switch ports/trunks, but am sorta confused about this option on the ZD1100. Why is it there and what does it do for me? I've never had a device that had a similar configuration option before. My WLAN is operating perfectly, with each user getting assigned to their correct VLAN, so I'm just curious. It's currently set to the same VLAN ID as the ZD's subnet, but I really can't experiment since the WLAN is actively used and I don't want to impact our users.
