This command sets the bridge priority for a specifi c multiple spanning tree instance. The instance <mstid>
is a number that corresponds to the desi red existing multiple spanning tree inst ance. The priority value is
a number within a range of 0 to 61440 in increments o f 4096.
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 intern al 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.
Syntax
spanning-tree mst priority <0-4094> <0-61440>
no spanning-tree m st priority <0-4094>
<0-4094> - multiple spanning tree instance ID.
<0-61440> - prio rity value (Range: 0 – 61440).
no - This command sets th e bridge priority for a specific multiple spa nning tree instance to the default
value, that is, 32768. The instance <0-4094 > is a number that corresponds to the desired existing
multiple spanning tree inst ance.
If 0 (defined as the default CIST ID) is passed as the <0-4094>, then this command sets the Bridge
Priority parameter for the common and internal spanning tree to the default value, that is, 32768.

This command adds an association between a multiple spanning tree instance and a VLAN. The VLAN
will no longer be associated with the common and internal spanning tree. The instance <0-4094> is a
number that corresponds to the desired existing multipl e spanning tree instance. The <1-3965>
corresponds to an existing VLAN ID.
Syntax
spanning-tree mst vlan <0-4094> <1-3965>
no spanning-tree mst vlan <0-4094> <1-3965>
<0-4094> - multiple spanning tree instance ID.
<1-3965> - VLAN ID (Range: 1 – 3965).
no - This command removes an associ ation between a multiple spanning tree i nstance a nd a VLAN.
The VLAN will again be associated with the common and internal spanning tree. The instance
<0-4094> is a number that corre sp onds to the desired existing multiple spanning tree instance. The
<1-3965> corresponds to a n existing VLAN ID.
