AT8404 Switching Commands
Page 2 - 13 AT8404 CLI Reference Manual
2.2.15.1 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 you specify an <mstid> parameter that
corresponds to an existing multiple spanning tree instance, you are configuring that multiple spanning tree instance.
If you specify 0 (defined as the default CIST ID) as the <mstid>, you are configuring the common and internal
spanning tree instance.
If the you specify cost, 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 path
cost value based on the Link Speed.
If you specify external-cost, this command sets the external path cost for this port for mst ‘0’ instance, to the default
value, i.e. a path cost value based on the Link Speed.
If you specify port-priority, 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.
2.2.16 spanning-tree mst instance
This command adds a multiple spanning tree instance to the switch. The parameter <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 switch is 4.
2.2.16.1 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 parameter <mstid> is a number that
corresponds to the desired existing multiple spanning tree instance to be removed.
2.2.17 spanning-tree mst priority
This command sets the bridge priority for a specific multiple spanning tree instance. The parameter <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 you specify 0 (defined as the default CIST ID) as the <mstid>, this command sets the Bridge Priority parameter
to a new value for the common and internal spanning tree. The bridge priority value is a number within a range of 0
