For RSTP configuration via CLI, we take the following ring network topology composed of 3 sets of
FOS-3128 Managed Switches, including Switch A, Switch B and Switch C for example to let the
users have a clear understanding of these RSTP commands. Under this network environment,
Switch A, Switch B and Switch C will be configured as Table 2-2, and the “Root Switch” will
automatically be determined by this network.
