ProSafe Managed Switch
If you specify port-priority, this command sets the priority for this port within a specific
multiple spanning tree instance or the common and internal spanning tree instance,
depending on the <mstid> parameter, to the default value.
Format no spanning-tree mst <mstid> <cost | external-cost | port-priority>
Mode
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.
Default
Format spanning-tree mst instance <mstid>
Mode
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
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
Format spanning-tree mst priority
<mstid> <0-61440>
