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 Switch
ing > STP > Advanced > MST Configuration.
2. Conf
igure the MST values:
• MST ID. S
pecify the ID of the MST to create. Valid values for this are between 1 and
4094.
• Priority. S
pecifies 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.
