Spanning Tree > STP Status
Spanning Tree > STP Status
You can display a summary of the current bridge STA
information that applies to the entire Switch using the
information screen . This screen displays the following
information .
information that applies to the entire Switch using the
information screen . This screen displays the following
information .
Spannng Tree State
Shows if the Switch is enabled to
participate in an STA-compliant network .
Spannng Tree Mode
Shows the type of protocol that
the Switch is using .
Brdge ID
A unique identifier for this bridge, consisting of
the bridge priority and MAC address (where the address is
taken from the Switch system) .
taken from the Switch system) .
Desgnated Root
The priority and MAC address of the
device in the Spanning Tree that the Switch has accepted
as the root device .
as the root device .
Root Port
The number of the port on the Switch that is
closest to the root . The Switch communicates with the
root device through this port . If there is no root port, then
the Switch has been accepted as the root device of the
Spanning Tree network .
root device through this port . If there is no root port, then
the Switch has been accepted as the root device of the
Spanning Tree network .
Root Path Cost
The path cost from the root port on the
Switch to the root device .
Root Maxmum Age
The maximum time (in seconds) a
device 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 . Any port that ages out STA
information (provided in the last configuration message)
becomes the designated port for the attached LAN . If it
is a root port, a new root port is selected from among
the device ports attached to the network . (References to
“ports” in this section mean “interfaces,” which includes
both ports and LAGs .)

Root Hello Tme
Interval (in seconds) at which the Switch
transmits a configuration message .
Root Forward Delay
The maximum time (in seconds) the
root device 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 .

Topology Changes Counts
The number of times the
Spanning Tree has been reconfigured .
Last Topology Change
Time since the Spanning Tree
was last reconfigured .
