Hello Time
Time (in seconds) that the root waits between sending configuration messages. This
time is advertised by the root and used by all devices and switches in the active
topology of the spanning-tree network.

Max Message Age
Time at which the configuration message used by the spanning tree algorithm
should be discarded. This time is advertised by the root and used by all devices and

Port
Port number.
PId (Port ID)
Port ID that is used to determine the role of the port in the spanning tree. The port
ID is expressed in the form port priority.port number.
ID is expressed in the form port priority.port number.
PCst (Port Cost)
Cost associated with each port. Lower numbers are generally assigned to ports
attached to faster media (such as FDX or CrossLink), and higher numbers are
generally assigned to ports attached to slower media (such as 2400-baud modem
links).
