Mstp Example Configuration - NETGEAR GS728TS Admin Manual

GS728TS, GS728TPS, GS752TS, and GS752TPS Gigabit Smart Switches

MSTP Example Configuration

This example shows how to create an MSTP instance from the GS728TS, GS728TPS,
GS752TS, or GS752TPS switch. The example network has three different GS728TS,
GS728TPS, GS752TS, or GS752TPS switches that serve different locations in the network.
In this example, ports 1–5 are connected to host stations, so those links are not subject to
network loops. Ports 6-8 are connected across switches 1, 2 and 3.

Perform the following procedures on each switch to configure MSTP:
1. Use the VLAN Configuration screen to create VLANs 300 and 500 (see
Configuration on page 110).
2. Use the VLAN Membership screen to include ports 1–8 as tagged (T) or untagged (U)
members of VLAN 300 and VLAN 500 (see
3. From the STP Configuration page, enable the Spanning Tree State option (see
Configuration on page 123).
4. In the Configuration Name field on the STP Configuration page, configure the name so that
it is the same on each switch, for example netgear-stp. By default, the Configuration Name
is the switch MAC address which means that it is unique for each switch.
Use the default values for the rest of the STP configuration settings. By default, the STP
Operation Mode is MSTP.
5. From the CST Configuration screen, set the Bridge Priority value for each of the three
switches to force Switch 1 to be the root bridge:
• Switch 1: 4096
• Switch 2: 12288
• Switch 3: 20480
