5.5.30. spanning-tree mst instance
This command adds a multiple spanning tree instance to the switch. The parameter mstid is a number within a
range of 1 to 4094 that corresponds to the new instance ID to be added. The maximum number of multiple
instances supported by the switch is 4.
Format spanning-tree mst instance <mstid>
Default None
Mode Global Config
5.5.31. no spanning-tree mst instance
This command removes a multiple spanning tree instance from the switch and reallocates all VLANs allocated to
the deleted instance to the common and internal spanning tree. The parameter mstid is a number that
corresponds to the desired existing multiple spanning tree instance to be removed.
Format no spanning-tree mst instance <mstid>
Mode Global Config
5.5.32. spanning-tree mst priority
This command sets the bridge priority for a specific multiple spanning tree instance. The parameter mstid <0-
4094> is a number that corresponds to the desired existing multiple spanning tree instance. The priority value is
a number within a range of 0 to 61440 in increments of 4096.
If you specify 0 (defined as the default CIST ID) as the mstid, this command sets the Bridge Priority parameter to
a new value for the common and internal spanning tree. The bridge priority value is a number within a range of
0 to 61440. The twelve least significant bits are masked according to the 802.1s specification. This causes the
priority to be rounded down to the next lower valid priority.
Format spanning-tree mst priority <mstid> <0-61440>
Default 32768
Mode Global Config
