Spanning-Tree Operation

802.1s Multiple Spanning Tree Protocol (MSTP)

Syntax: spanning-tree config-revision < revision-number >

This command configures the revision number you designate

for the MST region in which you want the switch to reside.

This setting must be the same for all switches residing in the

same region. Use this setting to differentiate between region

configurations in situations such as the following:

• Changing configuration settings within a region where you

want to track the configuration versions you use

• Creating a new region from a subset of switches in a current

region and want to maintain the same region name.

• Using the pending option to maintain two different

configuration options for the same physical region.

Note that this setting must be the same for all MSTP switches

in the same MST region. (Range: 0 - 65535; Default: 0)

Note: This option is available only when the switch is

configured for MSTP operation.

Syntax: spanning-tree max-hops < hop-count >

This command resets the number of hops allowed for BPDUs

in an MST region. When an MSTP switch receives a BPDU, it

decrements the hop-count setting the BPDU carries. If the hop-

count reaches zero, the receiving switch drops the BPDU. Note

that the switch does not change the message-age and

maximum-age data carried in the BPDU as it moves through

the MST region and is propagated to other regions. (Range: 1

- 40; Default: 20)
