5.1.11 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 a range from 1 to 127.
Default

tree to the default value.
Format
no spanning-tree max-hops
Mode

5.1.12 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 you specify an
<mstid>
parameter that corresponds to an existing multiple spanning tree instance, the
configurations are done for that multiple spanning tree instance. If you specify 0 (defined
as the default CIST ID) as the
<mstid>
, the configurations are done for the common and
internal spanning tree instance.
If you specify the
cost
option, the 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. You can set the path cost as a number in the range of
1 to 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’ i.e. CIST instance. You can set the external cost as a number in the range of 1
to 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 to 240 in increments of 16.
Default
cost: auto; external-cost: auto; port-priority: 128
Format
spanning-tree mst
<
mstid> {{cost <1-200000000> |
auto} |
