DESCRIPTION
Enter the index number of the STP port(s).
Enter the external path cost. Enter 0 for Auto.
Select the state of the STP port as enabled or disabled.
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 Yes to activate BPDU filter or No to deactivate it.
Select Yes to activate P2P MAC or No to deactivate it.
Select Yes to activate Migrate or No to deactivate it.
Click Apply to save the changes.
Click Cancel to discard the changes.
