2.2.13 spanning-tree max-age
This command sets the Bridge Max Age parameter to a new value for the common and internal spanning tree. The
max-age value is in seconds within a range of 6 to 40, with the value being less than or equal to
2 x (Bridge Forward
Delay - 1) .
2.2.13.1 no spanning-tree max-age
This command sets the Bridge Max Age parameter for the common and internal spanning tree to the default value.
2.2.14 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.
2.2.14.1 no spanning-tree max-hops
This command sets the Bridge Max Hops parameter for the common and internal spanning tree to the default value.
2.2.15 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.
