Configuring Multiple Spanning Tree Protocol

This example shows how to enable IEEE 802.1s Multiple Spanning Tree (MST) protocol on the switch and all
of the ports and to set the bridge priority.
To make multiple switches be part of the same MSTP region, make sure the Force Protocol Version setting for
all switches is IEEE 802.1s. Also, make sure the configuration name, digest key, and revision level are the same
for all switches in the region.
Note: The digest key is generated based on the association of VLANs to different instances. To ensure
the digest key is same, the mapping of VLAN to instance must be the same on each switch in the
region. For example, if VLAN 10 is associated with instance 10 on one switch, you must associate VLAN
10 and instance 10 on the other switches.

Using the Web UI to Configure MSTP

1. Create VLANs 10 and 20.
a. Access the Switching > VLAN > Status page.
b. Click Add to create a VLAN.
c. Select the VLAN ID-Individual option and enter 10.
d. Click Submit.
e. Repeat the steps to add VLAN 20.
2. Enable MSTP (IEEE 802.1s) on the switch and change the configuration name.
a. Changing the configuration name allows all the bridges that want to be part of the same region to
join.
b. Go to the Switching > Spanning Tree > Switch page.
c. From the Spanning Tree Admin Mode field, select Enable.
d. In the Configuration Name field, enter ubnt.
e. Click Submit.
3. Create two MST instances.
a. Go to the Switching > Spanning Tree > MST page.
b. From the MST page, click Add.
c. In the MST ID field, enter 10.
d. Associate MST ID 10 with VLAN 10 and assign a bridge priority of 16384.
e. Click Submit.
