DESCRIPTION
Click MSTP to edit MSTP settings on the Switch.
This field appears only in stacking mode. Click the drop-down list to choose the slot number of
the Switch in a stack.
This field displays the port number. In stacking mode, the first number is the slot ID and the
second is the port number. * means all ports.
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.
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).
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.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
