select the MSR mode.

The Switch supports port based STP Enable/disable function, and also provides

loop protect for each port to achieve loop eliminate when applies STP and MSR

functions.

4.4.1 STP Configuration

This page allows select the STP mode and configuring the global STP/RSTP Bridge

Configuration.

The STP mode includes the STP, RSTP, MSTP and Disable. Please select the STP

mode for your system first. The default mode is RSTP enabled.

After select the STP or RSTP mode, continue to configure the global Bridge

parameters for STP and RSTP.

After select the MSTP mode, please go to MSTP Configuration page.

RSTP is the abbreviation of 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 damage 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 and is specified in IEEE

802.1D-1998. Later, Rapid Spanning Tree Protocol (RSTP) was adopted and

represents the evolution of STP, providing much faster spanning tree convergence
