If the ‘external-cost’ token is specified, this command sets the external-path cost for MST instance

‘0’ i.e. CIST instance. The external pathcost can be specified as a number in the range of 1 to

200000000 or auto.

If "auto" is specified, the external pathcost value will be set based on 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. The port-priority value is a number in the range of 0 to 240 in increments

of 16.

Default

cost : auto; external-cost : auto; port-priorty : 128

Format

spanning-tree mst <mstid> {{cost <1-200000000> | auto

} |

{external-cost <1-200000000> | auto }| port-priority

Mode

Interface Config

no spanning-tree mst

This command sets the Path Cost or Port Priority for this port within the multiple spanning tree

instance or in the common and internal spanning tree to the respective default values. If the

<mstid> parameter corresponds to an existing multiple spanning tree instance, then the

configurations are done for that multiple spanning tree instance. If however 0 (defined as the

default 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 ‘external-cost’ token is specified, this command sets the external path cost for this port for

mst ‘0’ instance, 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.

Switching Commands

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 the software is 4.

Format

spanning-tree mst instance <mstid>

Mode

Global Config

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

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

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.

Format

Mode

Global Config

spanning-tree mst vlan

This command adds an association between a multiple spanning tree instance and a VLAN. The

VLAN will no longer be associated with the common and internal spanning tree. The instance

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

<vlanid> corresponds to an existing VLAN ID.

Format

spanning-tree mst vlan <mstid> <vlanid>

Mode

Global Config

no spanning-tree mst vlan

This command removes an association between a multiple spanning tree instance and a VLAN.

The VLAN will again be associated with the common and internal spanning tree. The instance

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

<vlanid> corresponds to an existing VLAN ID.

spanning-tree

This command sets the STP mode for a specific port-channel (LAG). This is the value specified

for STP Mode on the Port Configuration Menu. 802.1D mode is the default. The interface is a

logical slot/port for a configured port-channel. The

all

option sets

all configured port-channels

(LAGs) with the same option.
