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.
