To configure an MST instance:
1. To add an MST instance, configure the MST values and click Add:
• 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.
2. To delete an MST instance, select the check box next to the instance and click Delete.
3. To modify an MST instance, select the check box next to the instance to configure, update
the values, and click Apply. You can select multiple check boxes to apply the same setting
to all selected ports.
4. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
