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 from 0 through 4095, the priority is set to 0. The default priority is 32768.The valid range is 0-61440. • VLAN ID. The list contains all VLANs configured on the switch. Select a VLAN to associate with the MST instance. 3. Click APPLY to send the updated configuration to the switch.
