XS712T Smart Switch

Sample MSTP Configuration

This example shows how to create an MSTP instance from the XS712T switch. The example network has three different XS712T switches that serve different locations in the network. In this example, ports g1–g5 are connected to host stations, so those links are not subject to network loops. Ports g6–g8 are connected across switches 1, 2, and 3.

Ports g1–g5	Ports g1–g5
connected to hosts	connected to hosts

Ports g6–g8

connected to switch 2 and 3

Switch 1 root bridge

Switch 2

Ports g6–g8

Connected to switch 1 and 2

Switch 3

Ports g1–g5 connected to hosts

Perform the following procedures on each switch to configure MSTP:

1.Use the VLAN Configuration screen to create VLANs 300 and 500 (see Basic VLAN Configuration on page 85).

2.Use the VLAN Membership screen to include ports g1–g8 as tagged (T) or untagged (U) members of VLAN 300 and VLAN 500 (see VLAN Membership Configuration on page 86).

3.From the STP Configuration screen, enable the Spanning Tree State option (see STP Configuration on page 99).

Use the default values for the rest of the STP configuration settings. By default, the STP Operation Mode is MSTP and the Configuration Name is the switch MAC address.

4.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

Note: Bridge priority values are multiples of 4096.
