5.1.5.10 Reconfiguration times
The reconfiguration time for a Spanning Tree depends on the timer values for MaxAge and
Forward Delay.
The minimum reconfiguration time is: 2 × ForwardDelay
The maximum reconfiguration time is: 2 × Forward Delay + MaxAge
For the values recommended by the IEEE standard, the value for ten active STP switches
along a path beginning with the root switch is between 30 s and 50 s.
Switch-over time response to be expected for RSTP and RSTP with activated fast
ring detection
When using RSTP, expect switch-over times in the range from 100 ms to 2 s .
When using fast ring detection, expect switch-over times in the range from 100 ms to
500 ms .
The various roles of ports
The root port of a switch connects this switch to the root switch - either directly or via
another switch (designated switch).
The designated port is the port at a designated switch that is connected to the root port of
the next switch.
No additional switches/bridges are connected to edge ports . Termination devices are
connected to edge ports.
An alternate port is a path to the root, which, however, did not become a root port. I.e., this
port is not part of the active topology.
