The System Information page displays.
5. Select Switching > STP > Advanced > MST Configuration.
The MST Configuration page display.
6. Configure the settings for the MST instance:
• MST ID: In the MST ID field, specify the ID of the MST. The ID can be in the range
from 1 to 4094.
• Priority: In the Priority field, specify the bridge priority value for the MST instance.
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 you set the priority to any value between 0
and 4095, the switch automatically sets the value to 0. The range is from 0 to
61440. The default is 32768.
• VLAN ID: From the VLAN ID menu, select the VLAN that must be associated with
the MST instance.
