Spanning Tree Commands 4

revision

This command configures the revision number for this multiple spanning tree configuration of this switch. Use the no form to restore the default.

Syntax

revision number

number - Revision number of the spanning tree. (Range: 0-65535)

Default Setting

Command Mode

MST Configuration

Command Usage

The MST region name (page 4-152)and revision number are used to designate a unique MST region. A bridge (i.e., spanning-tree compliant device such as this switch) can only belong to one MST region. And all bridges in the same region must be configured with the same MST instances.

Example

Console(config-mstp)#revision 1

Console(config-mstp)#

name (4-152)

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.

Syntax

max-hopshop-number

hop-number- Maximum hop number for multiple spanning tree. (Range: 1-40)

Default Setting

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
