Default Setting
20
Command Mode
MST Configuration
Command Usage
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.
Example
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.
Syntax
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.
