CIST ID) is passed as the <mstid>, then the configurations are performed for the common and internal spanning tree instance.

If the 'cost' token is specified, this 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, to the default value, i.e. a pathcost value

based on the Link Speed.

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, i.e. 128.

▫ Format no spanning-tree mst <mstid> {cost | port-priority}

▫ Mode Interface Config

11.1.18 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 this

switch is 4.

▫ Format spanning-tree mst instance <mstid>

▫ Mode Global Config

11.1.18.1 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 instance <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 Global Config

11.1.19 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.

▫ Default 32768

▫ Format spanning-tree mst priority <mstid> <0-61440>

▫ Mode Global Config

11.1.19.1 no spanning-tree mst priority

This command sets the bridge priority for a specific multiple spanning tree instance to the default value, i.e. 32768. The instance

<mstid> is a number that corresponds to the desired existing multiple spanning tree instance.

If 0 (defined as the default CIST ID) is passed as the <mstid>, then this command sets the Bridge Priority parameter for the

common and internal spanning tree to the default value, i.e. 32768.
