14.
Argument Description
instance-id The MST instance ID. The range is 0 to 15.
priority Determines the likelihood that the switch will be chosen as the root switch.
<priority>
The range is 0 (highest likelihood) to 61440 (lowest likelihood) at increments of
4096. The default priority value is 32768.
The valid priority values are 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672,
32768, 36864, 40960, 45056, 49152, 53248, 57344, and 61440. All other values
are rejected.
Configuring the MSTP Interface Parameters

Setting the MSTP Port Priority
The mstp port priority command, in Interface Configuration mode, defines the MST port
priority. The no form of this command returns the interface to its default settings.
By default, the spanning tree port priority is 128.
If a loop occurs, the MSTP uses the port priority when selecting an interface to put into the
forwarding state. You can assign higher priority values (lower numerical values) to interfaces
to be selected first and lower priority values (higher numerical values) to interfaces to be
selected last. If all interfaces have the same priority value, the MSTP puts the interface with
the lowest interface number in the forwarding state and blocks the other interfaces.
