MST region view 

None 

Use the active region-configuration command to activate the settings of an MST 

(multiple spanning tree) region. 

Configuring MST region-related parameters (especially the VLAN mapping table) result 

in spanning trees being regenerated. To reduce network topology jitter caused by the 

configuration, MSTP (multiple spanning tree protocol) does not regenerate spanning 

trees immediately after the configuration; it does this only after you activate the new 

MST region-related settings or enable MSTP, and then the new settings can really take 

effect. 

This command causes the switch to operate with the new MST region-related settings 

you configured and spanning trees to be regenerated. 

Related command: instance, region-name, revision-level,  vlan-mapping modulo, 

and check region-configuration. 

# Activate the MST region-related settings.
