spanning-tree max-hops
This command sets the MSTP Max Hops parameter to a new value for the common and internal
spanning tree. The max-hops value is in a range of 1 to 127.
The no version of this command sets the Bridge Max Hops parameter for the common and internal
spanning tree to the default value.

This command sets the MSTP Max Hops parameter to a new value for the common and internal
spanning tree. The max-hops value is in a range of 1 to 127.

This command sets the Bridge Max Hops parameter for the common and internal spanning tree
to the default value, i.e. 20.

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. 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.
The pathcost can be specified as a number in the range of 1 to 200000000 or auto. If “auto” is
specified, the pathcost value will be set based on Link Speed.
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.
