4.6 Rapid Spanning Tree
Spanning Tree Protocol (STP)
provides tree topography for any arrangement of bridges. STP also provides one path
between end stations on a network, eliminating loops.
Rapid Spanning Tree Protocol (RSTP) -
While Classic Spanning Tree guarantees preventing L2 forwarding loops in a
general network topology, convergence can take up to 30-60 seconds. The convergence time is considered too long for
many applications. When network topology allows, faster convergence may be possible. The
Rapid Spanning Tree
Protocol (RSTP)
detects and uses of network topologies that provide faster convergence of the spanning tree, without
creating forwarding loops.
The devices support the following Spanning Tree protocols:
‧
Compatiable -- Spanning Tree Protocol (STP):
Provides a single path between end stations, avoiding and
eliminating loops.
‧
Normal -- Rapid Spanning Tree Protocol (RSTP) :
Detects and uses of network topologies that provide
faster spanning tree convergence, without creating forwarding loops.

Notice:
The Gigabit Ethernet Switch implement the Rapid Spanning Protocol as the default spanning tree
protocol. While select
“Compatibles”
mode, the system use the RSTP (802.1w) to compatible and
co work with another STP (802.1d)’s BPDU control packets.
This page is to enable/disable the Spanning Tree protocol. The switch support IEEE 802.1d Spanning Tree (STP), IEEE
802.1w Rapid Spanning Tree (RSTP). The screen in Figure 4-23 appears.
