bridge mst region revision level
Defines the revision level for a Multiple Spanning Tree (MST) region. One of three attributes (name, revi-
sion level, and a VLAN to MST instance association table) that defines an MST region as required by the
IEEE 802.1Q 2005 standard. Switches that share the same attribute values are all considered part of the
same MST region. Currently each switch can belong to one MST region at a time.
bridge mst region revision level rev_level
Syntax Definitions
rev_level A numeric value (0–65535) that identifies the MST region revision level
for the switch.
Defaults
By default, the MST revision level is set to zero.

Usage Guidelines
Specifying an MST region revision level is allowed regardless of which Spanning Tree operating mode or
protocol is currently active on the switch. However, MST configuration values, such as revision level, only
apply when the switch is operating in the flat Spanning Tree mode and using the MSTP.

-> bridge mst region revision level 1000
-> bridge mst region revision level 2000
