xStack® DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch Type This field allows the user to choose a desired method for altering the MSTI settings. The user has four choices. Add VID - Select this parameter to add VIDs to the MSTI ID, in conjunction with the VID List parameter. Remove VID - Select this parameter to remove VIDs from the MSTI ID, in conjunction with the VID List parameter. VID List (1-4094) This field is used to specify the VID range from configured VLANs set on the Switch that the user wishes to add to this MSTI ID. Supported VIDs on the Switch range from ID number 1 to 4094. This parameter can only be utilized if the Type chosen is Add or Remove. Click Apply to implement changes made. 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.
