MST Configuration

Use the Spanning Tree MST Configuration screen to configure Multiple Spanning Tree (MST)
on the switch.

To configure an MST instance:
1. Select Switching > STP > Advanced > MST Configuration.
2. Configure the MST values:
• MST ID. Specify the ID of the MST to create. Valid values for this are between 1 and
4094.
• Priority. Specifies the bridge priority value for the MST. When switches or bridges are
running STP, each is assigned a priority. After exchanging BPDUs, the switch with the
lowest priority value becomes the root bridge. The bridge priority is a multiple of 4096.
If you specify a priority that is not a multiple of 4096, the priority is automatically set to
the next lowest priority that is a multiple of 4096. For example, if the priority is
attempted to be set to any value between 0 and 4095, it will be set to 0. The default
priority is 32768.The valid range is 0–61440.
• VLAN ID. The menu contains all VLANs configured on the switch. Select a VLAN to
associate with the MST instance.
3. Click the Add button.
For each configured instance, the information described in the following table displays on the
screen.
