Configuring with Web Based Management

5.4 "Information" menu

SCALANCE W770/W730 to IEEE 802.11n Web Based Management

84 Configuration Manual, 11/2014, C79000-G8976-C323-03

If Spanning Tree is turned on, the information about the status of the instance selected in the

"Instance ID" drop-down list is displayed and the information about the configured ports is

shown in the table. The information shown depends on the Spanning Tree mode.

Description

The page contains the following boxes:

●

Spanning Tree Mode

Shows the set mode. You specify the mode in "Layer 2 > Configuration" and in "Layer 2 >

MSTP > General".

The following values are possible:

– '-'

– STP

– RSTP

– MSTP

●

Instance ID

Shows the number of the instance. The parameter depends on the configured mode.

●

Bridge Priority / Root Priority

Which device becomes the root bridge is decided based on the bridge priority. The bridge

with the highest priority (in other words, with the lowest value for this parameter) becomes

the root bridge. If several devices in a network have the same priority, the device whose

MAC address has the lowest numeric value will become the root bridge. Both

parameters, bridge priority and MAC address together form the bridge identifier. Since

the root bridge manages all path changes, it should be located as centrally as possible

due to the delay of the frames. The value for the bridge priority is a whole multiple of

4096 with a range of values from 0 to 32768.

●

Bridge Addresse / Root Addresse

The bridge address shows the MAC address of the device and the root address shows

the MAC address of the root bridge.
