Bridge Id: Show this switch’s current bridge priority setting and bridge
ID which stands for the MAC address of this switch.
Hello Time: Interval (in seconds) at which the root device transmits a
configuration message.
Max 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 age 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.
Fwd 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: Indicates if spanning tree topology is steady or undergoing
reconfiguration. (The time required for reconfiguration is extremely
short, so no values other that “steady” state are likely to be seen in this
field.)
Root ID: The priority and MAC address of the device in the Spanning Tree
that this switch has accepted as the root device. Each port has been
connected to the root device.
