spanning-tree mst instance
This command adds a multiple spanning tree instance to the switch. The instance <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 software is 4.
Format
spanning-tree mst instance <mstid>
Mode Global Config
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 instance
<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
spanning-tree mst priority
This command sets the bridge priority for a specific multiple spanning tree instance. The instance
<mstid> 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 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.
Default 32768
Format
spanning-tree mst priority <mstid> <0-61440>
Mode Global Config
no spanning-tree mst priority
This command sets the bridge priority for a specific multiple spanning tree instance to the default
value, i.e. 32768. The instance <mstid> is a number that corresponds to the desired existing
multiple spanning tree instance.
