Command Usage
A MSTI region is treated as a single node by the STP and RSTP
protocols. Therefore, the message age for BPDUs inside a 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)#
spanning-tree spanning-disabled
This command disables the spanning tree algorithm for the specified
interface. Use the no form to reenable the spanning tree algorithm for the
specified interface.
Syntax
[no] spanning-tree spanning-disabled
Default Setting
Enabled
Command Mode

Example
This example disables the spanning tree algorithm for port 5.
Console(config)#interface ethernet 1/5
