LABEL DESCRIPTION
MSTP Click MSTP to edit MSTP settings on the Switch.
Port This field displays the port number.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row
first to set the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Edge Select this check box to configure a port as an edge port when it is directly attached to a
computer. An edge port changes its initial STP port state from blocking state to
forwarding state immediately without going through listening and learning states right
after the port is configured as an edge port or when its link status changes.
Note: An edge port becomes a non-edge port as soon as it receives a Bridge Protocol Data
Unit (BPDU).
Root Guard Select this check box to enable root guard on this port in order to prevent the switch(es)
attached to the port from becoming the root bridge.
With root guard enabled, a port is blocked when the Switch receives a superior BPDU on
it. The Switch allows traffic to pass through this port again when the switch connected to
the port stops to send superior BPDUs.
