5.1.25 spanning-tree mst priority
This command sets the bridge priority for a specific multiple spanning tree in-
stance. The instance <mstid> is a number that corresponds to the desired ex-
isting multiple spanning tree instance. The priority value is a number within a
range of 0 to 61440 in increments of 4096.
This command accepts the value 0 for the mstid.
If 0 (defined as the default CIST ID) is passed as the <mstid>, then this
command sets the Bridge Priority parameter to a new value for the common
and internal spanning tree. The bridge priority value again is a number within
a range of 0 to 61440. The twelve least significant bits will be masked
according to the 802.1s specification. This will cause the priority to be
rounded down to the next lower valid priority.
