Mode Global Config
2.2.12.1 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
2.2.13 spanning-tree mst priority
This command sets the bridge priority for a specific multiple spanning tree instance.
The parameter
<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 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.
Default 32768
Format spanning-tree mst priority <mstid> <0-61440>
Mode Global Config
2.2.13.1 no spanning-tree mst priority
