Figure 7-23. Spanning Tree Port Settings
The Spanning Tree Port Settings page contains the following fields:
Select a Port
— Specifies the port number on which STP settings are to be to modified.
STP
— Enables or disables STP on the port.
Fast Link
— When checked, enables Fast Link mode for the port. If Fast Link mode is enabled for
a port, the
Port State
is automatically placed in the
Forwarding
state
when the port link is up. Fast
Link mode optimizes the time it takes for the STP protocol to converge. STP convergence can take
30-60 seconds in large networks.
Port State
— Indicates the current STP state of a port. If enabled, the port state determines what
forwarding action is taken on traffic. Possible port states are:
Disabled
— STP is currently disabled on the port. The port forwards traffic while learning
MAC addresses.
Blocking
— The port is currently blocked and cannot be used to forward traffic or learn MAC
addresses. Blocking is displayed when Classic STP is enabled.
Listening
— The port is currently in the listening mode. The port cannot forward traffic nor
can it learn MAC addresses.
