Fig. 8.10 Principle of Spanning Tree Protocol
Meanwhile, the rapid spanning-tree protocol (RSTP) defined in IEEE 802.1w dramatically
reduces the time of network convergence on the spanning-tree protocol (STP). It is easy
and fast to configure new protocol. The IEEE 802.1w also supports backward compatibil-
ity with IEEE 802.1d.
The switch provides STP, RSTP and MSTP. For more detail description of STP and RSTP,
refer to the following sections.

STP Operation
The 802.1d STP defines port state as blocking, listening, learning, and forwarding. When
STP is configured in LAN with double paths, switches exchange their information includ-
ing the bridge ID.
