bridge mst region name
Defines the name for a Multiple Spanning Tree (MST) region. One of three attributes (name, revision
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 name name
bridge mst region no name
Syntax Definitions
name An alphanumeric string up to 32 characters. Use quotes around string if
the name contains multiple words with spaces between them (e.g.
“Alcatel-Lucent Marketing”).
Defaults
By default, the MST region name is left blank.
Platforms Supported
OmniSwitch 6250
Usage Guidelines
• Use the no form of this command to remove the MST region name. Note that it is not necessary to
specify the region name to remove it.
• To change an existing region name, use this same command but specify a string value that is different
than the existing name. It is not necessary to first remove the old name.
• Specifying an MST region name is allowed regardless of which Spanning Tree operating mode or
protocol is currently active on the switch. However, MST configuration values, such as region name,
only apply when the switch is operating in the flat Spanning Tree mode and using MSTP.
