Figure 47. RSTP Advanced Port Configuration Page
This page displays the following information about the ports:
Port
Indicates ports 1 through 8. Use the All row to apply the same settings
to the STP Status, Priority, and Path Cost fields to ports 1 through 8.
Trunk
Indicates the trunk assignment of a port.
Link
Indicates if the port is connected to (Up) or disconnected from (Down)
another network device.
State
Indicates one of the following port states:
ˆ Blocking— A port that would cause a switching loop. In this state,
no user data is sent or received by the port. The port may go into
the forwarding state if the other links in use failed and the spanning
tree algorithm determines the port may transition to the forwarding
state. BPDU data is received in the blocking state.
ˆ Listening— The port processes BPDUs and awaits new
information that would cause the port to return to the blocking
state.
ˆ Learning— While the port does not yet forward frames (packets), in
this state the port does learn source addresses from frames
received and adds them to the filtering (switching) database.
ˆ Forwarding— A port that both receives and sends data. This
indicates normal operation. STP continues to monitor the port for
