2.6.1 Enable/Disable VLAN
In the 802.1Q VLAN page, you can enable/disable the tag-based VLAN function by clicking the (Enable) or (Disable) hyperlink beside the page header:
¾Enable – to activate the tag-based VLAN function (this will disable the port-based VLAN function).
¾Disable – to de-activate the tag-based VLAN function. (Any existing tag-based VLAN entries will be retained although tag-based VLAN functions will be disabled. Any retained port-based VLAN entries will auto enable.)
