Force10 Networks S2410s manual Spanning-tree mst instance, Spanning-tree mst priority

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.
