max-hops
This command configures the maximum number of hops in the region
before a BPDU is discarded. Use the no form to restore the default.

SAGE
An MSTI region is treated as a single node by the STP and RSTP protocols.
Therefore, the message age for BPDUs inside an MSTI region is never
changed. However, each spanning tree instance within a region, and the
internal spanning tree (IST) that connects these instances use a hop count
to specify the maximum number of bridges that will propagate a BPDU.
Each bridge decrements the hop count by one before passing on the BPDU.
When the hop count reaches zero, the message is dropped.

XAMPLE
Console(config-mstp)#max-hops 30
Console(config-mstp)#
mst priority
This command configures the priority of a spanning tree instance. Use the
no form to restore the default.
S
YNTAX
mst instance-id priority priority
no mst instance-id priority
instance-id - Instance identifier of the spanning tree.
(Range: 0-4094)
priority - Priority of the a spanning tree instance.
