Enables MST on the switch. This example shows how to enable MST on the switch: switch# configure terminal switch(config)# spanning-tree mode mst To disable MST on the switch, perform this task: Command switch(config)# no spanning-tree mode mst Purpose Disables MST on the switch and returns you to Rapid PVST+. Caution Changing the spanning tree mode can disrupt traffic because all spanning tree instances are stopped for the previous mode and restarted in the new mode. Note Because STP is enabled by default, entering a show running command to view the resulting configuration does not display the command that you entered to enable STP. Entering MST Configuration Mode You enter MST configuration mode to configure the MST name, VLAN-to-instance mapping, and MST revision number on the switch. For two or more switches to be in the same MST region, they must have the identical MST name, VLAN-to-instance mapping, and MST revision number. Note Each command reference line creates its pending regional configuration in MST configuration mode. In addition, the pending region configuration starts with the current region configuration.
