This field is used to specify the VID range from configured VLANs set on the Switch that the

to 4094. This parameter can only be utilized if the Type chosen is Add or Remove.

MSTP Port Information
This window displays the current MSTP Port Information and can be used to update the port configuration for an MSTI ID. If a
loop occurs, the MSTP function will use the port priority to select an interface to put into the forwarding state. Set a higher
priority value for interfaces to be selected for forwarding first. In instances where the priority value is identical, the MSTP
function will implement the lowest MAC address into the forwarding state and other interfaces will be blocked. Remember that
lower priority values mean higher priorities for forwarding packets. To view the following window, click L2 Features >
