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
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
Interface Configuration (Ethernet, Port Channel)
Example
This example disables the spanning tree algorithm for port 5.
spanning-tree cost
This command configures the spanning tree path cost for the specified interface.
Use the
no
form to restore the default.
Syntax

cost
- The path cost for the port. (Range: 0 for auto-configuration, 1-65535
for short path cost method, 1-200,000,000 for long path cost method)
