5.4 RSTP Status

RSTP VLAN Bridge Overview
 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, and the port connected to the root device.
