4 Command Line Interface

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)#

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.

Console(config)#interface ethernet 1/5

Console(config-if)#spanning-tree spanning-disabled

Console(config-if)#

spanning-tree cost

This command configures the spanning tree path cost for the specified interface. Use the no form to restore the default.

Syntax

spanning-tree cost cost no spanning-tree cost

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)

4-170
