the <mstid> parameter. You can set the path cost as a number in the range of 1–200000000
or auto. If you select auto the path cost value is set based on Link Speed.
If you specify the external-cost option, this command sets the external-path cost for MST
instance 0 that is, CIST instance. You can set the external cost as a number in the range of
1–200000000 or auto. If you specify auto, the external path cost value is set based on Link
Speed.
If you specify the port-priority option, 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
0–240 in increments of 16.
• cost—auto
• external-cost—auto

If you specify external-cost, this command sets the external path cost for this port for mst
‘0’ instance, to the default value, that is, 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.
