STP Information
The Spanning Tree, STP Information
page contains information on the
current status of the Spanning Tree.
Command Attributes
•
Spanning Tree State
— Indicates if the Spanning Tree Protocol is
currently enabled on the switch.
•
Bridge ID
— Identifies a unique identifier for the switch in the
Spanning Tree. The ID is calculated using the defined Spanning Tree
priority of the switch and its MAC address. The lower the Bridge ID,
the more likely the switch will act as the root.
•
Max Age
— The maximum time (in seconds) the switch can wait
without receiving a configuration message before attempting to
reconfigure. All device ports (except for designated ports) should
receive configuration messages at regular intervals. If the root port ages
out STP information (provided in the last configuration message), a
new root port is selected from among the device ports attached to the
network. (References to “ports” in this section means “interfaces,”
which includes both ports and trunks.)
•
Hello Time
— Specifies the time interval (in seconds) at which the
root device transmits a configuration message.
•
Forward Delay
— The maximum time (in seconds) the switch will
wait before changing states (i.e., discarding to learning to forwarding).
This delay is required because every device must receive information
about topology changes before it starts to forward frames. In addition,
each port needs time to listen for conflicting information that would
make it return to a discarding state; otherwise, temporary data loops
might result.
