SFTOS Command Reference for the S2410, Version 2.4.1.0 271
If the “port-priority” token is specified, 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, in other words, 128.
Syntax
no spanning-tree mst mstid {cost | port-priority}

Interface Config
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 SFTOS is 4.
The no version of 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.

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.
The
no version of this command sets the bridge priority for a specific multiple spanning tree
instance to the default value, in other words, 32768. The instance
mstid is a number that
corresponds to the desired existing multiple spanning tree instance.
