13.5 Rapid Spanning Tree Protocol Status
Click Advanced Application > Spanning Tree Protocol in the navigation panel
to display the status screen as shown next. See Section 13.1 on page 147 for
more information on RSTP.
Active Select this check box to activate RSTP on this port.
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).
Priority Configure the priority for each port here.
Priority decides which port should be disabled when more than one port
forms a loop in a switch. Ports with a higher priority numeric value are
disabled first. The allowed range is between 0 and 255 and the default
value is 128.
Path Cost Path cost is the cost of transmitting a frame on to a LAN through that
port. It is recommended to assign this value according to the speed of
the bridge. The slower the media, the higher the cost - see Table 26 on
page 148 for more information.
Apply 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.
Cancel Click Cancel to begin configuring this screen afresh.
