STP Port Settings
Multiple Spanning Tree Instance
MST or Multiple Spanning Tree Instance allows traffic of different VLAN to be mapped into different MST Instances.
GWN780x(P) Switch supports up to 16 independent MST instances (0~15) where each instance can be associated with many
VLANs.
MST Instance
MST Port Settings is used to configure the GE port / LAG group settings for each MST instance.
The table displays the MST parameters for each port.
MST Port Settings
Click on “Edit” button to edit the MST Port Settings for each Port/LAG individually and also the user can even specify the
Path Cost and Priority per Port/LAG as well.
Note: The valid range is 0~200000000. 0 is equal to auto
Edge Port
Set whether to enable Edge Port or disable it, by default it's on auto.
Notes:
● A port is considered as an edge port when it is directly connected to the user terminal or server, instead of any
other switches or shared network segments. The edge port will not cause a loop upon network topology
changes.
● In the edge mode, the interface would be put into the Forwarding state immediately upon link up. While in
auto mode it will detect if the port is an edge or not.
BPDU Guard
Set whether to enable BPDU Guard.
Note: BPDU Guard further protects your switch by turning this port into error state and shutdown if any BPDU
received from this port.
BPDU Filter
Set whether to enable BPDU Filter.
Note: Drop all BPDU packets and no BPDU will be sent.
Point-to-Point
Select Point-to-Point option (Auto, Enabled or Disabled). Default is Auto.
Note: determines the STP of link type for this port automatically if set to Auto.
