Maximum Age of STP Information
STP information (BPDU) is sent by the root switch at an age of "0" and at hello time
intervals. If a BPDU was received, every other switch sends its own configuration message
via the ports for which the switch itself is the designated switch. The age of the information
(BPDU) is increased by one second every time the information passes a switch.
Hello Time
Specifies the time interval within which the root bridge regularly reports to the other bridges
via BPDU.
Forward Delay
The forward delay value indicates how long the switch is to wait in order for the port state
in STP mode to change from "Discarding" to "Listening" and from "Listening" to "Learning"
(2 x forward delay).
