spanning-tree mst instance

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}

Mode

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.
