Besides Korenix ring technology, this switch also supports 802.1D-2004 version
Rapid Spanning Tree Protocol (RSTP). The new version of RSTP standard
includes 802.1D-1998 STP, 802.1w RSTP.
3.4.1.
RSTP
RSTP stands for Rapid Spanning Tree Protocol. If a switch has more than one
path to a destination, it will lead to message loops that can generate broadcast
storms and quickly bog down a network. The spanning tree was created to
combat the negative effects of message loops in switched networks. A spanning
tree uses a spanning tree algorithm (STA) to automatically sense whether a
switch has more than one way to communicate with a node. It will then select
the best path (primary), and block the other path(s). It will also keep track of the
blocked path(s) in case the primary path fails. Spanning Tree Protocol (STP)
introduced a standard method to accomplish this. It is specified in IEEE
802.1D-1998. Later, Rapid Spanning Tree Protocol (RSTP) was adopted and
represents the evolution of STP, providing for a much faster spanning tree
convergence after a topology change. This is specified in IEEE 802.1w. In 2004,
802.1w was included into the 802.1D-2004 version. This switch supports both
RSTP and STP (all switches that supports RSTP are also backwards compatible
with switches that support only STP).
This page allows you to enable/disable RSTP, and configure the global setting
and port settings.
RSTP Mode
You must first enable STP/RSTP mode before configuring any
related parameters. Parameter settings required for both STP
