GS716Tv3, GS724Tv4, and GS748Tv5 Smart Switches 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. Table 27.
