2.2.11 spanning-tree mst
This command sets the Path Cost or Port Priority for this port within the multiple
spanning tree instance or in the common and internal spanning tree. If you specify an
<mstid> parameter that corresponds to an existing multiple spanning tree instance, the
configurations are done for that multiple spanning tree instance. If you specify 0
(defined as the default CIST ID) as the
<mstid>
, the configurations are done for the
common and internal spanning tree instance.
If you specify the cost option, the command sets the path cost for this port within a
multiple spanning tree instance or the common and internal spanning tree instance,
depending on the
<mstid>
parameter. You can set the path cost as a number in the
range of 1 to 200000000 or auto. If you select auto the path cost value is set based on
Link Speed.
