CLI Command Reference
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.
Format
no spanning-tree mst <mstid> <cost | external-cost | port-prior-
ity>
Mode Interface Config
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.
Default none
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
parameter
<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
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 to 61440. The twelve least significant bits are
masked according to the 802.1s specification. This causes the priority to be rounded down to
the next lower valid priority.
